考虑地方电厂的可中断负荷补偿方法

Compensation methods for interruptible load in the presence of local power generation

针对供电紧张时地方电厂和可中断负荷资源之间的优化调度问题,重点研究了如何确定可中断负荷的经济补偿,使得供电侧和用户侧对于负荷中断量的选择能协调一致,并达到社会效益最优。设计了两种负荷中断补偿方法,即线性补偿和非线性补偿,并通过算例分析表明,与线性补偿相比,非线性补偿具有较低的单位补偿价格,即通过较小的经济补偿就能实现社会效益最优的负荷管理策略。

Optimization problem for dispatch between local power generation and interruptible load（IL） resources when electricity shortage happens is addressed.Emphasis is given to the issue of how to determine the economic compensation in the IL programs,with which a consistent choice for the load interruption by power supply-side and demand-side can be realized and at the same time the optimal social welfare can be achieved.For this purpose,two compensation methods,namely the linear compensation and the nonlinear compensation,are developed.Numerical simulation shows that as compared with the linear compensation,the nonlinear compensation leads to a lower compensation price,which means that using the nonlinear compensation method,load management with optimal social welfare can be achieved by a relatively small amount of economic compensation.
