Research on the Operation Strategy of Combined Wind-Photovoltaic-Storage System

With the rapid development of the new energy industry, the joint operation of wind and solar savings plays an important role in enhancing the stability and reliability of the power system. Taking an onshore wind farm as the research object, this paper discusses in depth the joint scheduling of new energy field station with battery storage and pumped storage, aiming to improve the prediction accuracy of new energy power generation and the overall operation efficiency of the system by optimizing the cooperative operation strategy of battery storage and pumped storage. The volatility and intermittency characteristics of new energy generation are first analyzed, and the impact of these characteristics on the stability of the power system is pointed out. Subsequently, an energy storage scheduling strategy based on forecast data is proposed to reduce the volatility of new energy generation and improve the accuracy of power prediction. Through an empirical study of a new energy power field, the effectiveness of rationally configuring battery energy storage and pumped storage systems in reducing prediction deviation and improving power system stability is verified, respectively. The study shows that the joint scheduling of battery energy storage and pumped storage can significantly reduce the prediction deviation of new energy power, which provides an important reference for the future joint operation of wind and solar savings.
