The present disclosure generally relates to data analytics in electrical distribution systems and, more particularly, to a system and a method for performing asset and energy management for an electrical distribution system.
Electrical distribution system is an electrical network which distributes electrical energy to an end user for utilization. The electrical distribution system may include multiple components such as, supply lines, transformers, switchgears, circuit breakers, switches, relays, fuses, cooling circuits, receptacles, utilization components, and the like. Components such as, switchgears, circuit breakers, switches, relays, fuses, and the like, protect other components of the electrical distribution system such as, the supply lines, the transformers, the utilization components, and the like, by monitoring conditions of the other components. The main aim of the electrical distribution systems is to provide sustainable, affordable, and uninterrupted power supply. To achieve this, asset management and energy management play a crucial role. Typically, asset management includes monitoring behaviour of assets of the electrical distribution systems and restoring faults that result in supply interruption for end users. The asset management is required to maintain functionality of the assets and to minimize breakdowns of the assets, to provide sustainable and uninterrupted power supply. For instance, consider there may be a short circuit on a power distribution line. The power distribution line may be connected to multiple assets of the electrical distribution systems. The asset management helps to identify the asset responsible for short circuit in the power distribution line.
While the energy management is required to plan energy production and energy consumption. Data related to multiple variables of the electrical distribution systems is used to perform the asset and energy management. The electrical distribution system includes multiple constituting components including electrical and mechanical components, and hence includes multiple variables such as electrical and mechanical variables. Generally, correlation between these variables is complex as the variables exhibit non-linearity i.e., there is no direct relationship between the variables and the relationship between the variables is not predictable from a straight line. In a non-linear relationship, changes in an output variable do not change in direct proportion to changes in input variables.
Conventional systems that predict data for performing the asset and energy management implement linear data modelling and analytics using machine learning. However, these systems may result into inaccurate or highly error prone predictions as the complexity due to the non-linearity and the complex correlation between the variables are not considered.
In an embodiment, the present disclosure discloses a method of performing asset and energy management for an electrical distribution system. The method comprises receiving measurement data of a plurality of input variables of an electrical distribution system, from one or more sensors associated with the electrical distribution system. Further, the method comprises generating a coefficient matrix for each output variable from one or more output variables used for asset and energy management. The coefficient matrix is generated based on effects of the plurality of input variables on corresponding output variable, using sparse regression on the measurement data. The coefficient matrix comprises one or more input variables from the plurality of input variables. Furthermore, the method comprises determining a plurality of system representations for each output variable, based on the corresponding coefficient matrix. Each of the plurality of system representations indicates a relationship between the one or more input variables and the corresponding output variable. Thereafter, the method comprises identifying a system representation from the plurality of system representations, for each output variable. The system representation is used to train a machine learning model for predicting a value of the corresponding output variable, for performing the asset and energy management for the electrical distribution system.
In another embodiment, the present disclosure discloses a computing system for performing asset and energy management for an electrical distribution system. The computing system comprises a processor and a memory. The processor is configured to receive measurement data of a plurality of input variables of an electrical distribution system, from one or more sensors associated with the electrical distribution system. Further, the processor is configured to generate a coefficient matrix for each output variable from one or more output variables used for asset and energy management. The coefficient matrix is generated based on effects of the plurality of input variables on corresponding output variable, using sparse regression on the measurement data. The coefficient matrix comprises one or more input variables from the plurality of input variables. Furthermore, the processor is configured to determine a plurality of system representations for each output variable, based on the corresponding coefficient matrix. Each of the plurality of system representations indicates a relationship between the one or more input variables and the corresponding output variable. Thereafter, the processor is configured to identify a system representation from the plurality of system representations, for each output variable. The system representation is used to train a machine learning model for predicting a value of the corresponding output variable, for performing the asset and energy management for the electrical distribution system.
In the present document, the word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment or implementation of the present subject matter described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. The terms “comprises”, “comprising”, or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a setup, device or method that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or device or method. In other words, one or more elements in a system or apparatus proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or apparatus.
Asset and energy management are an essential requirement for the electrical distribution systems to ensure availability, minimum breakdown, monitor energy consumption, and the like, of electrical assets. Generally, electrical distribution systems comprise multiple components. These components may include multiple variables such as, electrical, and mechanical variables. There is a complex correlation between the variables as the variables exhibit strong non-linearities, parametric dependencies, multiscale phenomena, and the like, making resulting system behavior very complex. In a non-linear relationship, changes in an output variable do not change in direct proportion to changes in any of input variables. Further, multiple input variables may contribute to the output variables making prediction of the output variable a difficult process. For instance, there can be multiple variables contributing to electric load. Thus, making accurate prediction of the electric load a difficult process. The input variables involve uncertainties and includes no direct relationship with the output variable. Moreover, the output variable is characterized to be non-linear that can undergo rapid changes due to environmental changes, addition of assets, demand patterns, maintenance requirements of customers, macroeconomic variations.
Accordingly, the present disclosure provides a method and a system for performing asset and energy management for an electrical distribution system. The present disclosure performs complex system analysis using non-linear dynamics on measurement data of the electrical distribution system. The present disclosure provides high accuracy in predicting future state of the electrical distribution system from the data, as the present disclosure considers the complex non-linear correlation between the variables through sparse regression.

Further, the present disclosure identifies a system representation that can ideally describe the complex non-linearity between the variables. The system representation can be used by a machine learning model to accurately predict future state of the electrical distribution system for performing the asset and energy management. The present disclosure can adapt to changing environment or complexities in a non-linear environment.

In one implementation, the computation data 204 may include, for example, input data 206, matrix data 207, system representation determination data 208, system representation identification data 209, and other data 210.
In an embodiment, the input module 211 may be configured to receive the measurement data of the plurality of input variables of the electrical distribution system 101 from the one or more sensors 102. The plurality of input variables may comprise at least one of, electrical variables, mechanical variables, and environmental variables, associated with the electrical distribution system 101. For example, the electrical variables may comprise variables such as current, voltage, power, power factor, harmonic distortions, energy, and the like. The mechanical variables may comprise wear and tear profiles, pressure, temperature, number of mechanical operations, and the like. The environmental variables may comprise variables such as temperature, humidity, and the like. In an example, consider that the electrical distribution system 101 comprises components such as, a circuit breaker, a fuse, a voltage regulator, and the like.

For example, the one or more sensors 102 may include the current sensor and the voltage sensor. In another embodiment, the one or more sensors 102 may be implemented outside the electrical distribution system 101.

The matrix generation module 212 may generate the coefficient matrix based on effects of the plurality of input variables on corresponding output variable, using sparse regression on the measurement data. The sparse regression may identify most relevant variables to predict a value of the output variable.
Coefficients of the sparse regression are sparse i.e., many variables are set to zero, selecting only the most relevant variables. In the present disclosure, the sparse regression is used on the plurality of input variables that exhibit strong non-linearity. The sparse regression identifies one or more input variables from the plurality of input variables based on the effects of the plurality of input variables on corresponding output variable. For instance, consider that the one or more input variables identified from the plurality of input variables comprise current, pressure, voltage, temperature, arc current and resistance, power for the output variable energy consumption. The sparse regression may generate the coefficient matrix comprising a binary value for each of the plurality of input variables. For example, the matrix generation module 212 may generate the coefficient matrix with ‘0’ value assigned to variables such as pressure, temperature, arc current, and the like, and ‘1’ value assigned to the one or more variables such as current, voltage, resistance, power, and the like. The coefficient matrix generated may be stored as the matrix data 207 in the memory 202.

Further, the system representation determination module 213 may be configured to determine the plurality of system representations for each output variable, based on the corresponding coefficient matrix. Each of the plurality of system representations indicates a relationship between the one or more input variables and the corresponding output variable. The system representation determination module 213 may determine one or more functions, where each function represents the relationship between the corresponding one or more input variables and the output variable. In an embodiment, the system representation determination module 213 may generate a candidate function matrix comprising the one or more functions associated with each of the corresponding one or more variables. A person skilled in the art will appreciate that the one or more functions may be generated in any other form and is not limited to matrix form. The coefficient matrix in combination with the candidate function matrix is used to generate determine the plurality of system representations. Each of the plurality of system representations comprise the one or more functions corresponding to each of the one or more input variables. Particularly, the plurality of system representations is a set of governing equations representing non-linearity of the electrical distribution system 101. Referring to the above-stated example, the output variable may be the energy consumption. The one or more variables may include the current, voltage, resistance, power, and the like. The functions may include, but not limited to, linear function, exponential function, logarithmic function, trigonometric function, and the like. The electrical distribution system 101 may be represented as a dynamical system of the form x′(t)=f(x(t)). For example, a system representation may be Y=six(x1)+cos 2(2*x2)+sin 3(5*x3).
In an example, the relationship between the current and the energy consumption may be defined by the linear function. The relationship between the resistance and the energy consumption may be defined by the linear function. In an example, arc resistance of the circuit breaker may exponentially vary with the temperature. Further, each of the plurality of system representations may include a weighted value associated with each of the one or more input variables, the weight indicating the relationship between the output variable and corresponding input variable. For example, consider when the function is a linear function. The weight may be “2”. The system representation may be y=2x. In an embodiment, the plurality of system representations may include differential equations. Exemplary system representations are shown below:
x0′=9.180+−0.119x0+0.026x1+−1.829x2+0.075x2{circumflex over ( )}2 Eq. (1)

x2′=3.076+−0.006x0+−0.409x2+0.012x2{circumflex over ( )}2 Eq. (3)
In an embodiment, the plurality of system representations is determined by variations in the plurality of input variables and threshold values associated with the plurality of input variables selected for the sparse regression. The plurality of threshold values may indicate a degree of relevancy between the plurality of input variables and the output variable. In an embodiment, the one or more variables selected by performing the sparse regressions may be varied to test different conditions, implementations, and the like. The plurality of system representations determined for each output variable may be stored as the system representation determination data 208 in the memory 202.
In an embodiment, the system representation identification module 214 may be configured to receive the system representation determination data 208 from the system representation determination module 213. Further, the system representation identification module 214 may be configured to identify a system representation from the plurality of system representations, for each output variable. Firstly, the system representation identification module 214 may determine an accuracy level of each of the plurality of system representations in determining the value of the output variable for the measurement data. Next, the system representation identification module 214 may identify the system representation with maximum accuracy level, from the plurality of system representations. The system representation ideally describing the electrical distribution system 101 is identified. In an embodiment, Akaike Information Criterion (AIC) may be used to identify the system representation from the plurality of system representations using the accuracy level as criteria.
A person skilled in the art will appreciate that any known methods other than the above-mentioned method may be used to identify the system representation from the plurality of system representations. The system representation may be used to train the machine learning model for predicting a value of the corresponding output variable using one or more machine learning techniques. For example, the machine learning model trained using the system representation may predict the values of the corresponding output variable to monitor asset life, cable & contact life, trip event categorization, energy consumption, and the like. The system representation identified may be simulated for future states to predict the value of the one or more output variables. The present disclosure identifies an ideal system representation that can be used to simulate future time states of behavior of the electrical distribution system 101 and hence can be used to accurately predict system output for desired performance such as, for the asset and energy management of the electrical distribution system 101.
