摘要

提出一种协调新型储能与无功资源的高比例分布式新能源电网无功电压日内优化控制方法。首先,分析高比例分布式新能源电网中新型储能与无功资源的响应特性与调节能力,构建多类型无功资源多时间尺度协调模式;然后,建立高比例分布式新能源电网双时间尺度无功电压优化控制模型,并给出基于二阶锥松弛的模型求解方法;最后,以改进的IEEE 33节点算例进行仿真验证。仿真结果表明,所提方法能充分利用新型储能与无功资源的调节能力,在保证控制精度的前提下为系统预留充足的动态无功储备,提高电网无功电压优化水平。

Abstract

With the increasing penetration of distributed renewable energy, the operational complexity of distribution systems intensifies, and the declining reactive power regulation capability exacerbates voltage quality issues. To address this challenge, this study proposes an intraday optimal voltage/reactive power control method coordinating novel energy storage systems with traditional reactive power resources in high-penetration distributed renewable energy grids. First, the response characteristics and regulation capacities of novel energy storage systems and various reactive power resources in such systems are analyzed, establishing a multi-time-scale coordination framework. Subsequently, a dual timescale intraday optimal reactive voltage control model is developed and solved using a second-order cone relaxation approach. Verification through the modified IEEE 33-bus test case demonstrates that the proposed method effectively harnesses the adjustment capabilities of multiple reactive resources. It maintains control precision while preserving adequate dynamic reactive power reserves, finally enhancing the grid's reactive power optimization capability.
