What is a two-part price-based leasing mechanism of shared energy storage?

A two-part price-based leasing mechanism of shared energy storage is presented. The SES-assisted real-time output cooperation scheme for VPP is designed. An optimal bidding model of VPP in joint energy and regulation markets is proposed. The method based on ISV-MDA is proposed to allocate the cooperation profit of VPP.

Can a VPP lease the use rights of next-day energy storage?

On this basis, the VPP can lease the use rights of next-day energy storage through the SES leasing market and then participate in day-ahead joint energy and regulation markets for higher profits with an optimal bidding strategy based on the SES-assisted real-time output cooperation scheme.

What is the difference between day-ahead and real-time energy base points?

Note that the day-ahead markets are usually cleared and settled for each hour, while the real-time energy base points fluctuate as the available power changes every 15 min, which results in deviations between the day-ahead and real-time set points and corresponding penalties.

How much profit did the Alliance make after leasing the SES resources?

Although the profit of the alliance in the energy market decreased after leasing the SES resources, the expected daily profit increased by $ 563, and the extra profit accounted for 30.3 % of the total profits of the alliance of $ 1860.

What is the difference between res generating units and energy storage units?

The RES generating units in the SES-assisted VPP can quickly respond to AGC signals through advanced control methods , , , , , , but there are defects in accuracy. On the contrary, energy storage has superior regulation performance but has the risk of battery degradation.

Why is energy storage important?

Energy storage, with fast response-ability and flexible charge–discharge capabilities, is widely used to assist the grid-connected operation of RES and improve the operational performance of RES generating units , , .
