According to a survey by the China Electricity Council, new energy distribution and storage projects have a low equivalent utilisation co-efficient of 6.1%, the lowest among the application scenarios, while the average for electrochemical energy storage projects is 12.2% (Figure 8).
An individual new energy supplier’s demand for energy storage is often insufficient to support the development of pumped storage power stations, and cooperative development or partial leasing can be adopted. From the perspective of capacity and power, power is more important than capacity when energy storage is mainly used to suppress fluctuations.
The power generation cost of new energy units after the installation of energy storage facilities is as follows: (7) C N S = M + P n ⋅ Δ Q ′ + S b + S o p = M + P n ⋅ ∫ Δ q min ′ Δ q f (q) ⋅ q ⋅ d q + S b + S o p (8) S b = R ⋅ Q s t r, S o p = N + K ⋅ Δ Q ′ ′ (9) Δ Q ′ ′ = Δ Q − Δ Q ′
When new energy units are equipped with energy storage facilities, the cost of energy storage is hedged against the total amount of penalty, and the output power range increases, so the curve moves from B1 to B3.
From the principle of energy storage, the most common and economically feasible options are usually pumped storage and electrochemical energy storage. Electrochemical energy storage has a fast response speed of milliseconds, which is mainly used for frequency modulation and short-term fluctuation suppression.
