Electrical Characteristics and Correlation Analysis in Smart Grid



The power grid system contains a large number of data sources, the amount of data and data types are very large, and the correlation between different kinds of data is also very complex. How to extract effective data sources from massive data, simplify the identification process, and effectively improve the accuracy of data processing is a necessary way to realize power grid intelligence. In this chapter, taking the air-conditioning circuit system of a complete building as an example, 11 features and 3 dependent variables are extracted, the correlation among features is analyzed by using three correlation analysis methods, and one dependent variable is selected. Based on the rough extraction of all the features, three feature selection methods are used to search for the optimal features, and finally, the optimal feature subset based on the selected dependent variables is obtained by comprehensive comparative analysis.
