About promoting participation in electric energy storage

Does energy storage configuration affect social welfare maximization (SWM)?

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).

What is the main goal of energy storage?

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.

Why is information asymmetry among electricity market members?

In the electricity market environment, the real information such as the operation and maintenance cost of the energy storage system and its construction cost, as well as the energy use cost of load users, is not easily disclosed to the public, which leads to the information asymmetry among market members [ 25 ].

Why is an economic configuration important for energy storage?

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.

Do load users and SES participate in day-ahead market clearing?

Cost allocation: Different from the literatures, a cost allocation mechanism considering the participation of load users and SES in the day-ahead market clearing is proposed based on the mechanism design theory of VCG to satisfy the properties of SWM, incentive compatibility (IC) and individual rationality (IR).

Can government subsidies help save energy storage costs?

However, the cost recovery of energy storage is complex, and government subsidies are still needed at this stage. To save government investment and improve the economic benefits of energy storage, the authorities need to choose an appropriate technology route so that the market can better allocate energy storage resources.
