Abstract:

为应对风电并网给电力经济调度带来的影响,构建了含风电场的多目标动态环境经济调度模型。该模型能同时兼顾燃料费用目标及污染排放目标,并计及阀点效应、网络损耗以及由风电不确定性引起的旋转备用需求。为求解该模型,达到为决策者提供最优调度方案集的目的,将基于分解的多目标进化算法(multi-objectiveevolutionaryalgorithmbasedondecomposition,MOEA/D)应用于动态调度领域。针对模型的复杂约束,在算法中加入对机组出力的实时调整及对约束违反量的适当惩罚,并利用归一化操作,避免算法向某一目标过度进化。经过对算例的仿真及对不同调度方案的对比分析,验证了所提调度模型的合理性以及改进MOEA/D算法解决此类问题的有效性。
