摘要
提出了一种储能的双层精细优化配置方法,结合运行与规划两个维度,实现储能容量和位置的精细配置;建立了双层规划模型,提出了对应求解方法,优化求解得到精细配置结果。精细配置模型以有源配电网成本收益为目标,针对不同的储能投资运营主体,制定了不同的成本收益模型,形成差异化目标优化配置。针对高渗透率分布式电源接入的配电网,提出的储能精细配置方法能够解决配电网电压合格率低、可再生资源浪费等问题,从而有效提高配电网可靠性和电能质量。
A two-layer detailed optimization method is proposed for the allocation of energy storage capacity and location,combining the distribution network operation and planning.A two-layer planning model is established and the corresponding solution method is proposed.The configuration results are obtained by optimizing the solution.The allocation model takes the cost of active distribution network as the goal.Different cost-economic models were made for different energy storage investors,realizing differentiation goal optimization allocation.As for the distribution network with high penetration of distributed power,the proposed method can solve problems of low qualified rate of distribution network voltages and waste of renewable resources.Therefore,the reliability and power quality of the distribution network can be improved effectively.
