Dynamic Economic Dispatch of Microgrid with Biomass Power Generation

Biomass energy is an important distributed generations and energy production, biomass energy utilization rate is very high. This paper focuses on the biomass power generation, photovoltaic power generation conditions, the load characteristics in Guangxi rural areas, were all analyzed by statistics, build a mathematical model of biogas power generation and bagasse power generation base on the statistics. According to different characteristics of the climate in summer and winter, with the grid and island two operation modes, propose the model of dynamic economic dispatch including the biomass generations, on the basis of subsidies for renewable energy prices, this model takes the minimum cost of power generation as the objective, in summer the biogas power generation and photovoltaic power generation as the main power supply, in the winter, the bagasse as the main power supply power, diesel generator as the load reserve function. The simulation results show that the model can fully evaluate the economy of distributed power users to meet the diverse needs, in order to help users to determine the system economic operation scheme.
