Bidding strategy and economic evaluation of energy storage 1. Introduction. The intermittent nature of renewable energy causes the energy supply to fluctuate more as the degree of grid integration of renewable energy in power systems gradually increases .This could endanger the security and stability of electricity supply for customers and pose difficulties for the growth of
. Therefore, dispatchable energy sources such as thermal power plant, nuclear power plant, and hydropower plant with suciently large reservoir or energy stor - age systems are strongly needed to cope with stochastic, non-dispatchable power generation for real time balancing of supply and demand without any interruption.

Previously charged power from within the cell (r +, c, ↑) is redirected away from the storage plant to flow out of the cell by reducing the charging rate; cf. Fig. 1(b). To illustrate this point, assume that a wind plant generates 1 MW of power that is absorbed by a storage plant within the cell through charging.

The bidding strategy of energy storage power station formulated in most papers relies on the day-ahead predicted price and regulation demand, and the effectiveness of the bidding strategy is based on the premise that day-ahead forecast is accurate [9, 10, 11].
In recent years, battery energy storages stations (BESSs) account for the largest proportion in large-scale energy storage power station projects due to its advantages such as rapid response, high integrated power, decreasing cost year by year and short construction cycle.
Flow chart of bidding strategy of BESS in DAM and RTM Usually, the lower limit of the price declaration stipulated by the electricity market is zero or even negative, which provides the opportunity for the power generators participating in the market to take risks.
