Two-step optimization method and device suitable for clearing check of inter-provincial reserve market

Abstract

The invention provides a two-step optimization method and device suitable for clearing and checking of an inter-provincial reserve market, and the method comprises the steps: improving the calculation efficiency of a large-scale power grid security constraint unit combination through the first-step large-time-granularity unit combination optimization, and then fixing the unit combination; and the accuracy of safety constraint economic dispatching is improved by adopting second-step small-time-granularity economic dispatching, and the optimization model introduces provincial dispatching and port plan double-balance constraints, so that integrated adjustment of a regional power grid direct dispatching unit and a provincial power grid dispatching and management unit is realized.

Description

technical field [0001] The invention relates to the technical field of power dispatch automation, in particular to a two-step optimization method adapted to the clearance and verification of the regional power grid inter-provincial reserve market. Background technique [0002] In view of the fact that there are many external incoming calls and the rapid development of new energy in the region, the power grid operation is facing increasing uncertainties and other actual situations, and the time scale of resource allocation is extended from the medium to long term to the day before and within the day. When the predicted reserve capacity of the provincial (municipal) power grid in the region fails to meet the safety requirements of the power grid, the reserve auxiliary service market will be activated, the resources of the whole region will be mobilized to provide support, and the power generation entities of the entire network will be encouraged to release their adjustment pote...

Problems solved by technology

[0004] In view of the fact that the prior art does not provide a security check optimization method that adapts to inter-provincial backup market clearing results, combined with the domestic market-oriented backup auxiliary service inter-provincial adjustment and clearing mechanism, it proposes a clearing check that is suitable for inter-provincial backup markets in regional power grids The two-step optimization method solves the problems of the low efficiency of the existing technology unit combination and the non-targeted optimization model for the verification of the inter-provincial backup clearing results of the regional power grid, and provides security and feasibility for the inter-provincial backup market clearing results of the regional power grid. It provides a practical and effective optimization method and fills the technical gap in the field of inter-provincial spare market clearance verification.
