A fuzzy theory based cross-region bilateral transaction curtailment model is proposed in this paper. The fuzzy curtailment set is defined, the fuzzy constraints are described, and the fuzzy optimization curtailment model is presented. This fuzzy optimization problem is solved as an unconstrained optimization one with the maximum entropy method. Test results show that the fuzzy curtailment set reduce the impact of the computational errors of the PTDF on the transaction curtailment and lead to less curtailment than does the crisp optimization model when slight violation of the operational limits is allowed, hence provide a more reasonable transaction curtailment model for the economic operation of the cross-region power market under transmission congestion conditions.

SUMMARYOptimal power flow (OPF) with transient stability constraints is a nonlinear optimization problem in functional space that is not easy to deal with precisely even for small-scale power systems. Instead of directly tackling this tricky problem, in this paper, OPF with transient stability constraints (OTS) is equivalently converted into an optimization problem in Euclidean space via a constraint transcription, which can be solved by any standard nonlinear programming techniques adopted by OPF. The transformed OTS problem has the same variables as those of OPF in form, and is tractable even for large-scale power systems with a large number of transient stability constraints.

“…1. The power market model form as the conventional optimal power flow (OPF) problem [12]- [14], and then propose an algorithm to derive both market clearing price and trade volumes of participants even for the case of the market-splitting. As indicated in the paper, since the proposed approach directly handles the problem with coexistence of the market and non-market participants, it can be used not only for the price evaluation of auction or bidding market but also for analysis of bidding strategy, congestion management and other constraints or factors.…”

This paper aims to develop a single price auction model with AC transmission network for Electricity Market in Japan, based on the principle of maximizing social surplus. Specifically, we first formulate the auction market as a nonlinear optimization problem, which has almost the same form as the conventional optimal power flow problem, and then propose an algorithm to derive both market clearing price and trade volumes of participants even for the case of market-splitting. As indicated in the paper, the proposed approach can be used not only for the price evaluation of auction or bidding market but also for analysis of bidding strategy and congestion management. Several numerical examples are used to demonstrate effectiveness of our method.
