Optimal Scheduling Of Microgrid Based On Improved Particle Swarm Optimization Algorithm

The world today is facing energy crisis and widespread environmental pollution increase, polluting fossil fuels will gradually be replaced by non-polluting clean energy. With economic development and social progress, the traditional way of generating electricity has been unable to meet today’s power users with high reliability, stability requirements demand. In micro-grid wind, light, storage, micro gas turbines, fuel cells and other distributed power configuration can effectively solve the energy crisis and environmental pollution problems. To maximize the benefits of clean energy, micro-grid system in the power sector has become a hot research. Micro-grid distributed to each micro-power optimization scheduling is a complex technical problems, and wind energy, solar power microgrid stochastic volatility for itself a certain impact security and stability. This paper made a more in-depth research on these issues.Optimal scheduling in microgrid is the core technology, the merits of scheduling strategy will directly affect the micro-economics of grid operation, reliability of supply, the study of micro-grid optimization scheduling theory has important theoretical value and the value of the works, but now stage of scheduling strategy microgrid still not perfect, dispatch and mode of operation, the program does not market integration. Contents of this paper on the micro-grid optimization scheduling made some improvements. In this paper, the establishment of micro-grid with wind, light, storage, microturbines, energy storage device consisting of optimization scheduling model. A more detailed description of each unit mathematical model and operating characteristics, is proposed in order to maximize the overall efficiency of the overall objective of the objective function, the establishment of a micro-grid in different operation modes specific constraints. We developed a micro-grid in grid operation, islanding Running Time period optimization scheduling policy.When micro power grid running, play a role in load shifting, to ensure the reliability of important load of electricity islands runtime. So that the entire grid power generation equipment can be fully utilized in the micro-grid and network operation and islanding operation when using different sub-periods Optimization scheduling strategy, using the improved PSO in micro-grid to solve the mathematical model to determine the individual micro-power output optimized to achieve micro-grid system runs the largest comprehensive benefits, and a numerical example to verify the correctness and feasibility of the algorithm.
