Abstract: For the provincial electricity market model in which the inter-provincial AC tie-lines are equivalent to load injections, the clearing results obtained from the models of market optimization clearing and corresponding security check need to be improved. With regards to such modeling strategy, the causes and effects of the deviations in the clearing results are analyzed in this paper. Then the regional power grid model-based optimization clearing model of provincial electricity spot market and the security check method are proposed. By consolidating the models of the entire power grid to generate the topology interface of the future period, the full network sensitivities are calculated to obtain the complete network sensitivity matrix for market optimization clearing and full network security verification iterations, such that the accurate power flow and locational marginal price (LMP) of the power grid can be derived. The case studies based on the actual system has verified the accuracy and effectiveness of the proposed method.

Key words: electricity spot market, LMP, dispatching, security check
