摘要

为解决新能源并网后产生的频率问题,提出一种考虑水风光互补的调频策略。首先,建立含风、水、光、荷的简单系统数学模型;其次,结合水轮机、风电机组、光伏及其调频策略所对应的代数微分方程和基于直流潮流的系统网络方程,推导出负荷扰动时水轮机、风电机组、光伏并网节点频率响应的频域解析式;最后根据解析式分析调频死区和调频控制参数等对系统频率的影响,提出一种水风光互补系统联合调频方案。在仿真软件PSD-BPA中搭建四机系统及实际电网的仿真模型,对调频方案的有效性和可行性进行验证,多场景下仿真结果表明该方法可提高系统一次调频能力。

Abstract

New energy increases in proportion year after year in Yunan Power Grid. In order to solve the frequency problem caused by the integration of new energy into the grid, this paper proposed a frequency regulation strategy in consideration of complementary water, wind and light. First, a simple system mathematical model with wind, water, light and charge was established. Secondly, by combining the algebraic differential equations corresponding to water turbine, wind turbine, photovoltaic, and their frequency regulation strategy with the system network equations on the basis of DC power flow, the frequency domain analytical expressions for the frequency response of water turbines, wind turbines, and photovoltaic grid connected nodes under load disturbances were derived. According to the analytical formula of the impact of frequency regulation dead zone and frequency regulation control parameter on the system frequency, a joint frequency modulation scheme for water solar complementary systems was proposed. A simulation model of the four machine system and the actual power grid was built in the simulation software PSD-BPA to verify the effectiveness and feasibility of the frequency regulation scheme. The simulation results in multiple scenarios indicate that this method can improve the system’s primary frequency regulation ability.
