Grid energy storage bidding

Is a multi-markets biding strategy decision model based on a grid-side battery energy storage system?

Abstract: A multi-markets biding strategy decision model with grid-side battery energy storage system (BESS) as an independent market operator is proposed in this paper.

How does transmission congestion affect the Bess bidding strategy?

The introduction of transmission congestion brings significant changes in market dynamics. Since the BESS does not have sufficient power output capacity to fully maintain demand block 1 online during congestion, curtailment occurs, and our methodology adjusts the BESS bidding strategy accordingly.

What is a joint energy-reserve procurement strategy?

Market operators use either sequential or joint energy-reserve procurement strategies. Joint markets clear energy and reserves simultaneously, accounting for interdependencies, using UC optimization at the unit level . Examples include U.S. markets such as PJM, CAISO, ERCOT, MISO, and NYISO , .

How does a high-price energy price spike affect Bess?

The proposed methodology detects this price spike, prompting the BESS to participate more actively in the energy market by purchasing energy earlier in the day to ensure sufficient SOC for selling during these high-price hours. This strategic behavior is reflected in Fig. 10, which shows the BESS awards throughout the day. Fig. 9.

How does reconnection of demand Block 1 affect energy prices?

The energy price increases from 22:00 to 24:00 as result of the reconnection of demand block 1 at hour 22:00, enabled by the semi-elastic load modeling approach. The reduction in the load of demand block 1 allows its reconnection while respecting the transmission network’s thermal limits.
