Multi-objective optimal operation of distributed energy storage considering user demand response under time-of-use price

The minimum of distribution network loss and voltage deviation is taken as the optimization objective, and a multi-objective optimal model of distributed energy storage is established considering user demand response under time-of-use price. Distributed energy storage is explored to improve the operation level of distribution network by the dynamic combination of user demand response under time-of-use price. An improved genetic algorithm is presented to solve the optimal model. The test results prove that the multi-objective optimization operation of distributed energy storage considering user demand response under time-of-use price can effectively reduce the distribution network loss and the voltage deviation. It also shows that the improved genetic algorithm has the characteristics of faster evolution speed and better solution results.
