摘要
为提高配电网对可再生能源的消纳能力并减轻可再生能源并网对配电网造成的影响,针对交直流混合配电系统,提出了一种考虑电压源型换流器和储能系统协调运行的储能容量双层优化模型,结合遗传算法与二阶锥规划方法对大规模非线性规划问题进行求解。最后,通过设置3种不同场景以验证模型的合理性和有效性。算例结果表明:储能系统和交直流混合配电系统协调运行能够有效抑制电压波动,提高储能系统的收益。
To improve the accommodation capacity of renewable energy in a distribution network while reducing the im⁃pact of renewable energy integration on the distribution network,a bi-level energy storage capacity optimization model for AC/DC hybrid distribution system is proposed with the consideration of the coordinated operation of voltage source converters and energy storage system(ESS).The large-scale nonlinear programming problem is solved by utilizing the genetic algorithm combined with the second-order cone programming.Finally,the rationality and effectiveness of the proposed model are verified by setting three different scenarios.The results of case studies demonstrate that the coordi⁃nated operation of ESS and AC/DC hybrid distribution system can effectively suppress voltage fluctuations and improve the revenue of ESS.
