Based on the actual data of wind-solar-storage power station, the energy storage capacity optimization configuration is simulated by using the above maximum net income model, and the optimal planning value of energy storage capacity is obtained, and the sensitivity analysis of scheduling deviation assessment cost is carried out.
New energy power plants can implement energy storage configurations through commercial modes such as self-built, leased, and shared. In these three modes, the entities involved can be classified into two categories: the actual owner of the energy storage and the user of the energy storage.
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.
In the context of increasing renewable energy penetration, energy storage configuration plays a critical role in mitigating output volatility, enhancing absorption rates, and ensuring the stable operation of power systems.
This paper proposes tailored energy storage configuration schemes for new energy power plants based on these three commercial modes.
It also studies the control method of energy storage system to improve the friendliness of wind and solar power generation, based on the control strategies such as smoothing new energy output fluctuations, tracking planned power generation, peak shaving and valley filling, and participation in system frequency modulation.

On July 5, 2025, a joint venture composed of China Energy Construction China Power Engineering International, East China Electric Power Design Institute and Hunan Thermal Power Construction Co., Ltd. officially signed an early working agreement with Abu Dhabi Future Energy Company (Masdar) in Oman for the early work of the Ibri 3 photovoltaic energy storage power station project in Oman, marking the official entry of this major new energy project into the performance stage.
