| dc.title | Modeling and simulation of microgrid integrated with wind and solar power generation | en_US |
| dcterms.abstract | With the emergence of energy problems and people's higher and higher requirements for power quality, safety and reliability, the disadvantages of the traditional large-scale centralized power grid have been increasingly exposed. Distributed generation, a new and efficient power generation mode with strong environmental protection, high flexibility and modularization, shows a broad development prospect. The system's safety and dependability can be increased by using distributed energy from a variety of power sources. The microgrid is crucial to the conventional huge power grid since it is an entirely independent system. This study examines the modeling and simulation of microgrid systems, which include wind power, photovoltaic, and energy storage systems, while taking into account a number of advantages of microgrid systems. The main research contents are as follows: | en_US |
| dcterms.abstract | 1) To simulate and examine the properties of the wind power generation system, MATLAB/Simulink is utilized, and also the photovoltaic power generation system in order to confirm the accuracy of the models and the efficiency of the maximum power point tracking algorithm. These models are based on a detailed analysis of the operating principles and mathematical models of wind power generation and photovoltaic power generation in microgrid systems. Introduces the general model of battery, analyzes the working principle and mathematical model of bi-directional converter, builds a simulation model based on lithium battery, and verifies the role of battery in maintaining the stability of microgrid system through Simulink simulation, which lays a foundation for the following research. | en_US |
| dcterms.abstract | 2) The working principle and mathematical model of three-phase bridge PWM inverter are analyzed. The inverter is effectively controlled by Park transform. Simulink simulation shows that the inverter can output AC with stable voltage and frequency. | en_US |
| dcterms.abstract | 3) The steady-state simulation and fault simulation of the microgrid system including wind power generation, photovoltaic power generation and battery under different configurations are carried out with MATLAB to verify the stability of the microgrid model. | en_US |
