novel transmission pricing scheme based on point-to-point tariff and transaction pair matching for pool market

transmission pricing scheme is a key component in the infrastructure of power market, and pool is an indispensable pattern of market organization; meanwhile, pay-as-bid (pab) serves as a main option to determine market prices in pool. in this paper, a novel transmission pricing scheme is proposed for pool power market based on pab. the new scheme is developed by utilizing point-to-point (ptp) tariff and introducing an approach of transaction pair matching (tpm). the model and procedure of the new scheme are presented in detail. apart from the advantages of existing transmission pricing schemes, such as ensuing open, fair and non-discriminatory access, proper recovery for investment as well as transparency, the new scheme provides economic signals to promote the maximum use of the existing transmission network, encourages appropriate bidding behaviors in pool, and helps to reduce the possibility of the enforcement of market power and the appearing of price spikes; thus improves market operation efficiency and trading effects. in order to testify the effectiveness of the proposed scheme, a case based on ieee 30-bus system is studied.
