摘要
光伏电源的输出功率受到光照、温度等自然因素的影响,呈现出间歇性和随机性的特点,导致功率波动较大。较大的功率波动会对电网的频率和电压稳定性产生严重影响,甚至可能引发电网崩溃等严重事故。为减少光伏接入带来的功率波动,提出储能协同下光伏多源接入功率波动的引力搜索算法(Gravitational Search Algorithm,GSA)。定义光伏与储能协同标准,并按照多源节点设置原则,构建储能协同下的光伏多源接入电网。根据多源接入电网中的功率波动特性,确定GSA参数的取值范围,完成光伏多源接入功率波动GSA控制算法的设计。实验结果表明,所提方法可将功率极值差控制在200 kW以内,且不会对光伏电网的发电能力造成影响,可以提高电网的供电质量。
The output power of photovoltaic power sources is influenced by natural factors such as light and temperature,exhibiting intermittent and random characteristics,leading to significant power fluctuations.Large power fluctuations can have a serious impact on the frequency and voltage stability of the power grid,and may even lead to serious accidents such as power grid collapse.To reduce power fluctuations caused by photovoltaic access,a GSA control algorithm for power fluctuations in photovoltaic multi-source access under energy storage synergy is proposed.Define collaborative photovoltaic energy storage standards and construct photovoltaic multi-source access to the power grid under energy storage collaboration based on the principle of multi-source node setting.Based on the power fluctuation behavior in multi-source access to the power grid,determine the range of GSA parameters and complete the GSA control algorithm for photovoltaic multi-source access power fluctuation.The experimental results show that the proposed method can control the power extreme difference within 200 kW without affecting the power generation capacity of the photovoltaic grid,and can improve the power supply quality of the grid.
