Inter-province link line power consumption transaction coordinated networking matching method

Abstract

The invention relates to an inter-province link line power consumption transaction coordinated networking matching method which comprises the steps of on the condition that a power grid inter-province transaction restriction and safety restriction constraining are satisfied, determining an electric power amount which requires purchasing or selling in real time; determining a safety restraining value and a least transaction amount, establishing an optimization model target function, calculating the optimization model target function, and obtaining an optimal connection transaction total amount; calculating a transaction amount matching value between provinces, using the transaction amount to be purchased by each province as an element for forming a set A, and using the transaction amount to be sold as an element for forming a set B, performing order reducing arrangement on the elements in the set A and the set B, and acquiring the province with highest to-be-purchased transaction amount and the province with highest to-be-sold transaction amount for transaction. The inter-province link line power consumption transaction coordinated networking matching method has technical effects of realizing real-time recommending for the inter-province electric power transaction, improving inter-province power grid coordination and linkage capability, improving electric power utilization rate, and optimizing resource utilization.

Description

technical field [0001] The invention belongs to the technical field of electric power design and automatic matching of electricity transactions, and specifically relates to an overall planning and networking matching method for inter-provincial tie-line electricity transactions that can realize cross-regional power generation control and electricity transactions. Background technique [0002] In recent years, the supply and demand situation of my country's electricity market has undergone great changes. The capacity of large and medium-sized generating units put into operation each year is above 10GW, but the growth rate of industrial electricity consumption cannot be increased simultaneously. The utilization hours of thermal power have decreased, and the standby capacity of generating units has increased significantly. . At the same time, the decline in load rate, the widening of the peak-to-valley difference, and the increasing integration of new energy into the grid have b...
