摘要
可以按对用户的补偿方式,将可中断负荷(IL---interruptible load)分为停电前低电价补偿和停电后高赔偿2类。迄今为止,对低电价IL与高赔偿IL的研究一直是孤立的。为有效遏制用户侧的市场力,提高备用容量配置和稳定控制的经济性,应充分利用这2种方式的不同经济特性及其互补性。为此,从风险管理观点提出这2种IL的协调模型和优化算法,使对低电价IL的确定性补偿与对高赔偿IL的风险补偿之和最小,其中暂不涉及与发电侧备用市场的协调。仿真验证该模型的合理性和算法的有效性。
There are two kinds of compensation fashions for interruptible loads （IL）, namely low price compensation which is independent of power cut occurrence and high compensation which is performed only after actual power cut. The interruptible loads with low price （ILL） and the interruptible loads with high compensation （ILH） have been studied separately till now. Based on the viewpoint of risk management, this paper analyzes their different economic properties, points out that their coordination is beneficial to restrain market power and reduces the cost of reserve capacity and system stability. Taking the sum of the deterministic reduction of revenue resulting from ILL and the risk of compensating ILH as the objective function, the coordination models and optimization algorithms are proposed. Simulation results are presented to validate the method.
