For its appreciable utilization rate

non-food biomass energy is an important future mode of distributed generation and energy production. This paper focuses on biomass power generation

photovoltaic power generation conditions

and analyzes the load characteristics in Guangxi rural areas prior to building a mathematical model of marsh gas power generation and bagasse power generation based on statistics. According to different characteristics of climate in summer and winter while considering the two operation modes grid-connection and islanding

a microgrid dynamic economic dispatch model including biomass generation is proposed. On the basis of subsidies for renewable energy prices

this model takes the minimum cost of power generation and minimum power deviation as the objective. In summer

marsh gas power generation and photovoltaic power generation is the main power supply

in winter

bagasse is the main power supply

while diesel generation plays the role as load reserve. Simulation results show that the model can fully evaluate the economy of distributed power users to meet their diverse needs by providing rural areas rich in non-food biomass energy with an independent scheme for microgrid solution.
