%X 在光伏与储能联合发电系统中，考虑到弃光现象以及储能系统在输出功率与荷电状态方面的限制，本文提出了一种基于虚拟同步机控制的光储并网策略，旨在解决弃光问题并提升光伏能源的利用率。该策略严格遵循国家标准，制定弃光控制准则，优化电站的能量管理。在有功功率控制方面，针对储能系统的充放电功率达到上限时，采用功率限幅控制策略，并结合两个比例积分调节器(PI控制器)对功率交换进行约束，从而有效防止储能系统出现过充电和过放电的风险。通过MATLAB/SIMULINK仿真与实验数据的验证，证明该控制策略在理论和实践中均具有较好的可靠性与可行性。
In the integrated photovoltaic (PV) and energy storage power generation system, considering issues such as curtailment of photovoltaic output and the limitations of the energy storage system in terms of output power and state of charge, this paper proposes a photovoltaic and storage grid-connected strategy based on Virtual Synchronous Machine (VSG) control. This strategy aims to address the issue of photovoltaic curtailment and improve the utilization of photovoltaic energy. The strategy adheres strictly to national standards, establishes guidelines for curtailment control, and optimizes the energy management of the power plant. For active power control, a power limiting strategy is implemented when the charging and discharging power of the energy storage system reaches its upper limits. This is combined with two Proportional-Integral (PI) controllers to regulate power exchanges, thereby effectively preventing the risk of overcharging and over discharging of the energy storage system. Simulation using MATLAB/SIMULINK and experimental data verification demonstrate that the proposed control strategy is reliable and feasible in both theoretical and practical applications.
