摘要(Abstract)：

针对高比例新能源接入的弱电网中系统电压调控难度显著增大的问题，提出一种储能充放电参与电压调节的优化调度策略与辅助服务补偿机制。首先，构建了一个省级电网日前三阶段协调调度框架，该框架包含日前现货市场出清、日前无功计划以及储能调压阶段。其次，在储能调压阶段建立了以“调整储能日前调峰计划、补偿其调峰收益损失”为核心的优化调度模型，旨在通过调节储能的有功出力来支撑系统电压。然后，设计了与模型相匹配的调压辅助服务成本补偿与分摊方案，从而在保障电压安全的同时，维护储能作为独立市场主体的合理经济收益。最后，基于改造后的IEEE 39节点系统以及西藏某地区电网进行仿真，验证了所提方法的有效性。
To address the increased difficulty of voltage regulation in weak power grids with high renewable energy penetration, this paper proposes an optimal scheduling strategy for energy storage systems(ESSs) to participate in voltage regulation through coordinated charging and discharging, together with a corresponding ancillary service compensation mechanism. First, a three-stage day-ahead coordinated scheduling framework for a provincial power grid is established, consisting of day-ahead spot market clearing, day-ahead reactive power scheduling, and an ESS-based voltage regulation stage. Next, an optimal scheduling model centered on adjusting the day-ahead peakshaving schedule of ESSs while compensating for the resulting loss of peak-shaving revenue is developed for the voltage regulation stage to support system voltage by regulating the active power output of ESSs. Subsequently, a compensation and cost allocation scheme for voltage regulation ancillary services is designed to align with the proposed scheduling model, ensuring voltage security while maintaining the reasonable economic returns of ESSs as independent market participants. Finally, simulations conducted on a modified IEEE 39-bus system and a power grid in Xizang verify the effectiveness of the proposed method.
