Abstract

The present invention proposes a power system economic scheduling method based on a finite-time average consensus algorithm. By designing a finite-time average consensus algorithm, the optimal incremental cost and optimized power generation can be obtained on the premise that the generator meets certain operating constraints. , to solve the economic dispatch problem of the power system in a limited time, and realize that the incremental cost of each generator tends to be consistent. The method of the invention enables the economic dispatching problem of the electric power system to be solved within a limited time, reduces the communication cost, meets the requirement of fast dispatching of the smart grid in the future, and has wider applicability.

Description

technical field [0001] The invention belongs to the technical field of power system economic dispatching, in particular to an electric power system economic dispatching method based on a finite time average consistency algorithm. Background technique [0002] Emerging smart grid architectures help to further explore some of the fundamental challenges in power distribution systems, such as economic dispatch (ED). Economic dispatch means that the generator sets allocate the total required power to each generator set under the condition that the operating cost is the lowest and the power constraints of the generators are satisfied. Traditional solutions include λ iteration method and gradient search method, which are mainly used to solve the situation when the cost function is a convex function. Other more complex methods are used to solve the case when the cost function is non-convex, including genetic algorithm (GA), particle swarm optimization (PSO) and the latest improved ...
