上游充廷大￥ Problems of Uniform-Pricing model SHANGHAI IIAO TONG UNIVERSITY A pricing method (early in the New England electricity market)suggested that the system clearing price was 5/MW and the generator G2 received its bid price of 30 MW,thereby gaining a congestion uplift.The congestion uplift is allocated by loads demand.This is certainly unreasonable.And this is the biggest problem of the Uniform-Pricing model. Another pricing method suggest that the clearing price should be 30$/MW.According to this method,there is no congestion uplift in the market.However,the generator Gl would consider it unfair.Because the bid price of Gl is lower than the clearing price,which will result in“Output redundancy”. 2016/12/22A pricing method (early in the New England electricity market) suggested that the system clearing price was $ 5 / MW and the generator G2 received its bid price of $ 30 / MW, thereby gaining a congestion uplift. The congestion uplift is allocated by loads demand. This is certainly unreasonable. And this is the biggest problem of the Uniform-Pricing model. Another pricing method suggest that the clearing price should be 30$/MW. According to this method, there is no congestion uplift in the market. However, the generator G1 would consider it unfair. Because the bid price of G1 is lower than the clearing price, which will result in “Output redundancy”. 2016/12/22 23 Problems of Uniform-Pricing model
