光伏发电系统与储能装置协调运行控制技术

Coordinated Operation Control Technology for Photovoltaic Power Generation Systems and Energy Storage Devices

太阳能光伏发电是新时代能源短缺背景下诞生的新型发电方式,具有发电能源可再生的特性,能够有效满足目益增长的电能需求。然而光伏发电系统接入配电网后,可能会产生电压越限问题,因而需要增设储能装置,通过此装置与光伏发电系统协调运行防控电压越限问题。为此,文章提出了限制反向功率流、计划运行、削峰运行、控制电压四种控制策略,并通过仿真分析验证了这些控制策略的效果,选出了限制反向功率流、控制电压两种最佳的协调运行控制策略。

Solar photovoltaic power generation is a new type of power generation method that emerged in the context of energy shortage in the new era.It has the characteristics of renewable power generation and can effectively meet the growing demand for electricity.However,after the photovoltaic power generation system is connected to the distribution network,there may be voltage limit exceeding problems,so it is necessary to add energy storage devices to coordinate with the photovoltaic power generation system to prevent and control voltage limit exceeding problems.For this purpose,the article proposes four control strategies:limiting reverse power flow,planned operation,peak shaving operation,and controlling voltage.The effectiveness of these control strategies is verified through simulation analysis,and the best coordinated operation control strategies of limiting reverse power flow and controlling voltage are selected.
