【摘要】：合理的裝機容量是減少棄風、優(yōu)化電力系統(tǒng)運行、減少風電商損失的有效方法。風電場裝機容量的確定主要受電網(wǎng)對風電接納能力、風電場風資源狀況和風電商運營方式的影響。提出采用多目標分層優(yōu)化決策方法求解風電場合理的裝機容量。第一層以電力系統(tǒng)環(huán)境經(jīng)濟調(diào)度為目標,充分發(fā)揮風電的節(jié)能減排效應,計算分析不同典型日負荷下的風電接納能力,獲得多條風電接納水平曲線;第二層以第一層電網(wǎng)最佳風電接納水平為基礎,根據(jù)風電場隨機模擬風速時序曲線,以風電場棄風電量與欠風電量期望最小為目標,兼顧風電場商的期望利益,建立隨機機會約束規(guī)劃模型評估風電場最佳裝機容量。仿真算例驗證了所提優(yōu)化模型的有效性與合理性。
[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.
