引入一种柔性有载调压变压器（FOVRT）拓扑结构

通过FOVRT进行调压和无功的协调配合

在此基础上提出一种含FOVRT的日前日内多时间尺度电压无功动态优化模型。日前阶段考虑离散型设备的小时级无功优化

根据分布式电源和负荷的预测数据

得到离散型补偿设备在不同时段内的最优调节方案;结合FOVRT连续无级调压能力

在日内阶段考虑分布式电源与FOVRT无功出力进行分钟级无功优化

仿真结果验证所提模型及方法的有效性和合理性。

Abstract

In order to solve the problem of voltage fluctuation caused by high proportion of new energy connected to the power grid

the paper introduces a flexible on-load voltage regulating transformer（FOVRT） topology. Through FOVRT

the coordination of voltage regulation and reactive power can realize the efficient utilization of reactive power regulation equipment in the power grid. Firstly

the working principle and mathematical model of FOVRT are analyzed

and then a multi-time scale voltage reactive power dynamic optimization model with FOVRT is proposed. According to the forecast data of distributed power supply and load

the optimal adjustment scheme of discrete compensation equipment in different time periods is obtained. Combined with FOVRT continuous stepless voltage regulation capability

minute level reactive power optimization is carried out considering distributed power supply and FOVRT reactive power output in intra-day stage to achieve the optimal network loss and node voltage deviation. Finally

the improved IEEE 33-node distribution network is simulated

and the simulation results verify the validity and rationality of the proposed model and method.
