一种基于价格弹性矩阵的居民峰谷分时电价激励策略

需求响应(DR)是利用价格信号和激励机制来保证电力系统安全可靠和经济运行的重要措施.传统价格激励在所有时间段的激励作用是一致的,可能导致对某个特定时间段的预测精度不够.研究了需求价格弹性矩阵(PriceElasticity Matrix of Demand,PEMD),提出了一种基于弹性效应权重的改进价格弹性矩阵模型....

An incentive strategy of residential peak-valley price based on price elasticity matrix of demand

Using price signal and an incentive mechanism,Demand Response(DR)is an important measure to ensure the safe,reliable,and economic operation of a power system.The incentive effect of traditional price incentive is the same in all periods,resulting in insufficient prediction accuracy in any particular period.In this paper,the Price Elasticity Matrix of Demand(PEMD)is studied,and an improved price elasticity matrix model based on the weight of the elasticity effect is proposed.The advantage of the model is that it can unify the rigid load and the flexible load,and set the weight for the price impact of different periods on other periods.The structure and calculation method of the price elasticity matrix determined by the price policy and load type is proposed.Finally,the effectiveness of the model is verified by simulation.The results show that the method can reduce peak power consumption by 4.23%and increase valley value power consumption by 4.86%.
