Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] figure 1 It is the flow chart of the particle swarm algorithm. Initialize the system parameters. The number of particles is generally 20-40. For most problems, 10 particles can achieve better results, and the value here is 40. The length of the particles, that is, the space dimension, is determined by the optimization problem, here is the number of schedulable distributed power sources. The maximum number of iterations can be set freely, and the value here is 1000. The initial values ​​of particle velocity and position are randomly generated.

[0024] Enter the iterative cycle, from the first iteration to the maximum number of iterations, after each iteration, the individual extremum and the global extremum are obtained and updated according to the comparative fitness value. During each iteration, the particle updates its s...

Abstract

The invention discloses a microgrid economic dispatching method based on a particle swarm optimization algorithm. Particle Swarm Optimization (PSO) algorithm makes full use of its own experience and swarm experience to adjust the state of particles, which can effectively optimize the system parameters. Its advantage lies in solving some optimization problems of continuous functions. In view of theabove situation, particle swarm optimization algorithm is applied to the economic dispatching of micro-grid. Firstly, the mathematical model of micro-power generation is established, and then the economic dispatching model of micro-power grid is established according to the dispatching criterion, and the economic optimal dispatching strategy is put forward. According to the constraint conditions,a micro-grid economic dispatching program based on particle swarm optimization algorithm is compiled. The results show that this algorithm can be used in micro-grid economic dispatching effectively and reasonably to allocate the output of micro-generators and achieve economic dispatching.

Description

technical field [0001] The invention relates to the field of economic scheduling of micro-grids, in particular to a micro-grid economic scheduling method based on particle swarm optimization algorithm. Background technique [0002] As a powerful supplement to the centralized power supply system, the distributed power generation system has certain advantages in terms of the economy of power supply and the degree of pollution to the environment. However, the power generation cost of distributed power and the pollution to the environment cannot be ignored. Connecting distributed power to the grid in the form of a microgrid is the most effective way to maximize the energy efficiency of distributed power. Therefore, the economic dispatch research of microgrid has received the attention of many scholars. [0003] So far, people have applied a variety of algorithms to the economic dispatch optimization research of microgrid, such as genetic algorithm, particle swarm optimization ...
