【摘要】：合理的装机容量是减少弃风、优化电力系统运行、减少风电商损失的有效方法。风电场装机容量的确定主要受电网对风电接纳能力、风电场风资源状况和风电商运营方式的影响。提出采用多目标分层优化决策方法求解风电场合理的装机容量。第一层以电力系统环境经济调度为目标,充分发挥风电的节能减排效应,计算分析不同典型日负荷下的风电接纳能力,获得多条风电接纳水平曲线;第二层以第一层电网最佳风电接纳水平为基础,根据风电场随机模拟风速时序曲线,以风电场弃风电量与欠风电量期望最小为目标,兼顾风电场商的期望利益,建立随机机会约束规划模型评估风电场最佳装机容量。仿真算例验证了所提优化模型的有效性与合理性。
[Abstract]:Reasonable installed capacity is an effective method to reduce wind abandonment, optimize power system operation and reduce wind power loss. The determination of the installed capacity of wind farm is mainly influenced by the power grid's ability to accept wind power, the wind resource condition of wind farm and the operation mode of wind power company. A multi-objective hierarchical optimization decision method is proposed to solve the reasonable installed capacity of wind farm. The first layer takes the environmental and economic dispatch of power system as the goal, gives full play to the energy saving and emission reduction effect of wind power, calculates and analyzes the wind power acceptance capacity under different typical daily loads, and obtains a number of wind power acceptance level curves. The second layer is based on the optimal wind power acceptance level of the first layer of power grid, according to the wind farm stochastic simulation wind speed time series curve, taking the expected minimum of wind farm abandoned wind power and underwind power as the goal, taking into account the expected interests of wind farm operators. A stochastic chance constrained programming model is established to evaluate the optimal installed capacity of a wind farm. A simulation example shows the validity and rationality of the proposed optimization model.
