[Abstract]:With the increasingly serious energy crisis and environmental pressure, the development and utilization of renewable energy is the development trend of new energy strategy. The effective way to solve the problem of grid connection in distributed generation system. In the face of the continuous access of distributed generation in the power network, the type and capacity of distributed micro-grid power supply can be reasonably configured, which can ensure the reliability of power supply and reduce the construction of micro-grid. It is of great significance to plan cost and improve the environmental friendliness of microgrid. Based on this, based on the theory of power capacity construction at home and abroad and combining the operation characteristics of microgrid, the following work is carried out in depth: 1) aiming at the independent operation of microgrid structure, Based on the analysis of the key factors affecting the selection and capacity allocation of the system, taking the minimum net cost of system investment and operation cost as the optimization goal, the system is selected and the capacity configuration is optimized by using Homer software. The sensitivity simulation of the influencing factors verifies the correctness of the analysis. It studies the optimal configuration of the micro-grid power supply which operates independently, considering the economy of the system, the reliability of the power supply and the environmental protection, synthetically considering the economy of the system, the reliability of the power supply and the environmental protection. This paper analyzes the influence of different optimization models on the optimal allocation of power supply. The lowest annual cost of the system, which takes into account the investment cost, operation cost, fuel cost, environmental cost and reliability cost of the system, is the optimal objective function. Based on the adaptive weighted particle swarm optimization (AWPSO) algorithm, the optimization program is written in Matlab to simulate and analyze the optimal configuration of power supply under different optimization models and verify the power balance under the capacity configuration. The feasibility and correctness of the proposed model are verified. (3) considering the economy, reliability and environmental protection of the power supply, the influence of different generation scheduling strategies on the optimal allocation of power supply is analyzed to take into account the investment cost of the equipment. The operating cost, fuel cost, and the energy transaction cost of the system with the main network are the lowest annual cost of the system. The optimal allocation model of the power supply is established. The model is also based on the adaptive weighted particle swarm optimization (AWPSO) algorithm. An optimization program is written in Matlab to simulate and analyze the optimal configuration of power supply under different target oriented generation scheduling strategies and to verify the power supply balance under this configuration. At the same time, the pollution control cost of pollutant emissions is taken as the environmental protection index. The significance of calculating and analyzing the dispatching strategy for improving the environmental performance of microgrid is analyzed. The validity and correctness of the proposed strategy are verified by an example.
