Multi-objective optimization model of electricity consumption for customers considering equipment consumption correlation

Given the background of electricity market, the electricity consumption optimization can reduce consumers' energy cost, and also help to reduce the peak load and improve the accommodation level of clean energy. Aiming at solving the problem of consumers' insufficient management of their own electricity consumption, a multi-objective optimization model of electricity consumption is proposed considering the correlation of equipment electricity consumption. First, the cross-correlation coefficient is adopted to identify the consumption correlation among various electricity equipment based on the historical load data of consumers, and the significance of the consumption correlation is analyzed by silhouette index. Next, a multi-objective optimization model is constructed and the optimal electricity consumption strategy is obtained to maximize the consumer-side economy and comfort benefits. Finally, the results of case studies on a Zhejiang stir-fried tea enterprise in China show that the proposed model is feasible and effective. (C) 2021 The Authors. Published by Elsevier Ltd.
