Under the framework of an open electricity market, DG and controllable loads participated in real-time operation of the grid. The concept of VPPs included the integration of DERs, such as DGs, controllable loads, and EMS, into VPPs to make them more accessible and manageable in the energy market.
In recent years, with the increase in the proportion of new energy connected to the grid, the main goal of energy storage on the load side and energy storage users is to maximize the overall interests.
An economic configuration for energy storage is essential for sustainable high-proportion new-energy systems. The energy storage system can assist the user to give full play to the regulation ability of flexible load, so that it can fully participate in the DR, and give full play to the DR can reduce the size of the energy storage configuration.
The value of a user load is the change in the total social welfare before and after the user participates in the market clearing. Let W ~ all be the social welfare of all members participating in the system market and ‐ − W ~ ‐ ses be the social welfare of the new system market not including SES.
Based on the poor utilization ratio and high use cost of energy storage configured on the user side, the controllability of adjustable load and the rationality of energy storage configuration are two key points that need to be considered for social welfare maximization (SWM).
The load target provides the DR Adjustment target for the whole period, which can better guide load shaping and promote the consumption of new energy.
