Energy storage bidding price analysis

How is the bidding strategy implemented?

The bidding strategy is implemented on the real-time price signals of Fig. 4 (the average of ten MCS) and is tabulated in Table 2. In this table, the two-level bids (one for energy and one for FRP) when the FRU or FRD prices are greater than 0.5$/MWh are demonstrated.

What is the bidding strategy of ESS based on energy and FRP price signals?

The bidding strategy of ESS based on energy and FRP price signals in order to maximise its profitability is described in Section 4. The case study and numerical results are investigated in Section 5 and eventually, the concluding remarks are presented in Section 6.

When should a bid be greater than the energy capacity?

According to Fig. 3, the bid should be greater than with the energy capacity equal to in order to approach an optimal energy purchase. The FRU will be enabled if the ESS submits a bid with power level equal to the desired FRU value and a price between and .

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

What is the proposed bidding mechanism for energy trades and FRP?

The proposed mechanism is a two-level bidding action that the ESS should submit: one for energy trades and the other for FRP. The proposed solution is simulated on the IEEE 118-bus test system and MCS is performed to attain the expected real-time realised position.

How a domestic energy storage system compared to last year?

In the first half of the year, the capacity of domestic energy storage system which completed procurement process was nearly 34GWh, and the average bid price decreased by 14% compared with last year. In the first half of 2023, a total of 466 procurement information released by 276 enterprises were followed.
