In view of the increasing trend of the proportion of new energy power generation, combined with the basic matching of the total potential supply and demand in the power market, this paper puts forward the bidding mod. With the rapid development of new energy, whether wind power and photovoltaic. 2.1. Role of new energy units in bidding marketAt present, in order to encourage the fully consumption of new energy, most markets have not require. The market supply and demand curves for new energy units entering the market are shown in Fig. 1. In the picture, B1, B2, and B3 are the supply curves when the fluctuation suppr. In this paper, the simulation calculation is based on the actual operation data of a wind farm in GD province, where the installed capacity is 130 MW, and the typical daily bid o. This paper proposes to take new energy units into the category of market bidding, and develops a matching fluctuation suppression mechanism, and gives the strategy of energ.

Why are the energy storage configuration demands lower than the proposed strategy?
Due to the absence of microgrid requirements for reserved power and inertia, the energy storage configuration demands are lower than those of the proposed strategy. Furthermore, as shown in Fig. 9, both the minimum rotational kinetic energy and the reserved power are significantly reduced.
How much storage capacity should a new energy project have?
For instance, in Guangdong Province, new energy projects must configure energy storage with a capacity of at least 10% of the installed capacity, with a storage duration of 1 h . However, the selection of the appropriate storage capacity and commercial model is closely tied to the actual benefits of renewable energy power plants.
Energy storage configuration models were developed for different modes, including self-built, leased, and shared options. Each mode has its own tailored energy storage configuration strategy, providing theoretical support for energy storage planning in various commercial contexts.
What is the maximum rated power of the configured energy storage?
The maximum rated power of the configured energy storage is 266 kW, accounting for approximately 23% of the total installed capacity of renewable energy. The maximum rated capacity of the configured energy storage is 399kWh. The corresponding scheduling scheme, energy storage operating state and inertia are illustrated in Fig. 7 a–j.
How can energy storage configuration models be improved?
On the other hand, refining the energy storage configuration model by incorporating renewable energy uncertainty management or integrating multiple market transaction systems (such as spot and ancillary service markets) would improve the model's practical applicability.
What constraints must the energy storage station satisfy?
The constraints that the energy storage station must satisfy include the capacity and power constraints of the energy storage configuration, as well as the constraint on the unit cost of the energy storage service. The capacity and power constraints are shown in Eqs. (10 – 11). The unit cost constraint of the energy storage service is as follows:
