Design and Implementation of Micro-grid System for Station with Hybrid Photovoltaic and Wind

Abstract

Microgrid control is a key technology for microgrid access to the conventional grid. This paper analyzes and summarizes the control strategy of the power station. This paper analyzes and summarizes the control strategies of photovoltaic power generation and wind power generation micro-grid. Firstly, the structure and function of the power station Photovoltaic and wind power micro-grid system are introduced and demonstrated. Second, the functions and effects of the battery are accurately applied to the system. Finally, the self-healing operation of a microgrid is proposed to ensure the normal and stable operation of the system. A microgrid is the backup power source of the power station by self-repairing and using energy storage technology. This scheme can adopt different control strategies according to the operation mode of the microgrid. The program can extend the battery life of substation. Based on the principle of the most efficient utilization of renewable energy, this paper studies the development and utilization of renewable energy optimization under different working modes. On the basis of ensuring the load power supply-demand and meeting the battery power consumption state, the optimal energy scheduling strategy under different operating modes is proposed, and the corresponding optimization model with the minimum operating cost as the objective is established.
