Alternating current-direct current smart home micro-grid operation method based on particle swarm algorithm

Abstract

The embodiment of the invention provides an alternating current-direct current smart home micro-grid operation method based on a particle swarm algorithm. Voltage, current and power of a micro-grid are optimally calculated through the particle swarm algorithm, and 100 percent grid connection of new energy sources can be realized; power generation advantages of a distributed power supply are sufficiently played and the utilization rate of clean energy sources is improved; a home micro-grid can express a pure resistive property on an electric supply, and harmonic pollution, caused by power generation of the new energy sources and power electronic equipment, on the electric supply is eliminated and power factors are improved; time-sharing constant power of the home micro-grid can be realized, and the difficulty of scheduling an upper-grade power grid is reduced and the stable operation capability of the upper-grade power grid is improved; the technical problems that the utilization rate of the new energy sources is not enough and the micro-grid causes impact on the upper-grade power grid, and supply-demand balance of electric energy and the quality of the electric energy are seriously influenced are solved. The embodiment of the invention further provides an alternating current-direct current smart home micro-grid operation device based on the particle swarm algorithm.

Description

technical field [0001] The invention relates to the field of home microgrids, in particular to an AC / DC intelligent home microgrid operation method based on particle swarm algorithm. Background technique [0002] Today's energy and environmental issues are increasingly prominent, and the development and utilization of renewable energy has become a consensus. The vigorous development of new energy will have an impact on the city power, and its intermittency and unpredictability seriously affect the balance of power supply and demand and power quality. The traditional power grid operation mode is that the power generation end follows the user end to adjust the power generation, which is difficult to cope with the large-scale access of intermittent energy. In order to ensure its own safe operation, the power grid adopts strict restrictions on new energy power generation, resulting in the current actual grid-connected rate of new energy being less than 20%.
