|
摘要
大规模间歇性风电和大容量核电基地并网给电力系统调峰带来了新的挑战,分析了新一代核电机组参与调峰运行的特性,提出了考虑核电机组参与的多类型电源系统联合调峰优化模型,通过求解模型获取不同类型电源间的日调峰优化策略;针对模型中的非线性函数和递归约束条件,提出了线性化处理方法,将原模型转化为混合整数线性规划模型进行求解。通过修改的IEEE-24节点系统进行测试计算,验证了方法的有效性。
Large-scale intermittent wind power and largecapacity nuclear power units bring new challenges to peaking of power systems. This paper analyzes the operation characteristics of new generation nuclear power units. A joint peaking optimization model for power systems with multi-type power units considering participation of nuclear power units is proposed. The model is used to obtain daily peaking strategy for different types of power units. For the nonlinear function and recursive constraints in the model, a linearization method is proposed to transform the original model into a mixed integer linear programming model. Finally, the test results of modified IEEE-24 nodes system verify effectiveness of the method.
