摘要
首先用等效持续负荷曲线分析系统的可靠性,确定系统的电量不足期望值。进而分析系统在市场环境下的备用容量成本,根据备用市场所独有的特性得到其出清过程,然后对VOLL值的确定进行多种方法的对比研究。以社会效益最大为目标函数,通过算例可以得出最佳备用容量和它的分配方法。与传统的方法比较,验证了该方法在市场环境下的有效性。
In the market environment,social benefit can combine the reliability of the system and economy together.Firstly,this paper uses equivalent load duration curve to analyze the system reliability to determine the system＇s expectation energy not supplied.Analysis the cost of reserve capacity in the market environment,and according to the characteristics of the reserve market to get the process of voidance,then determine numerical value of VOLL by comparative study using a variety of methods.Using the greatest social benefits as a model,through an example,the best reserve capacity and the best allocation can be calculated.Comparing with the traditional methods,It can be educed that the method is effective in the market environment.
