A New Electricity Contract Decomposition Method with Less Market Risk and More Competition Fairness
Electricity contracts should be decomposed to each unit involved and each time interval covered in the executing period of the contract in power pool. Traditional decomposition methods always focus on just fairness or economy, neglecting the influence of the decomposition results on market competition. This paper presents an electricity contract decomposition method with less market risk and more competition fairness. The market supply-demand ratio (SDR) index is introduced in the process of decomposition to mitigate the fluctuations of marginal prices, thus reducing the market price risk. At each time interval, the accomplishment rate (AR) index is applied to guarantee the fairness of the decomposition among units. The must-run ratio (MRR) index is taken to screen the market players with market power. By finely-tuning contract decomposition results, the risk of price spikes could be minimized and the fairness of market competition could be guaranteed as well.
