A Method for Coordinated Networking and Matching of Inter-provincial Tie Line Electricity Transactions

Abstract

The scheme of the present invention relates to a method for overall planning, calculation and matching of power consumption transactions between different provinces, specifically including determining in real time the value of electricity that needs to be purchased or sold by each province under the constraints of cross-provincial transaction restrictions and safety restrictions of the power grid; determining the safety Constraint value and the minimum transaction volume, establish the optimization model objective function, solve the optimization model objective function, and obtain the optimal contact transaction total value; solve the transaction volume matching value between each province, and use the transaction volume that needs to be purchased in each province The value is used as an element to form a set A, and the value of the transaction volume that needs to be sold is used as an element to form a set B, and the elements in the set A and set B are sorted in descending order to obtain the province with the largest transaction volume that needs to be purchased and the transaction volume that needs to be sold Trade with the province with the highest value. It realizes the real-time recommendation of cross-provincial power trading, improves the inter-provincial power grid coordination and linkage ability, enhances the utilization rate of power energy, and has the technical effect of optimizing the utilization of resources.

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...

Problems solved by technology

At the same time, the decline in load rate, the widening of the peak-to-valley difference, and the continuous increase of new energy grid connections have brought great difficulties to the grid's peak regulation and new energy consumption.
