Abstract

The invention provides a laboratorial intelligent microgrid system based on various distributed power sources. The system comprises a primary system and a secondary system. The primary system comprises a photovoltaic power generation system, an energy storage system, a wind power system, a diesel power generation system and load equipment, wherein the photovoltaic power generation system is composed of a photovoltaic cell panel, a photovoltaic direct current distribution box and a photovoltaic inverter; the energy storage system is composed of a lithium battery pack and an energy storage bidirectional converter; the wind power system is composed of a vertical axis wind turbine, a horizontal-axis wind turbine, a vertical axis wind turbine controller, a horizontal-axis wind turbine controller and a wind power system distribution box; the load equipment comprises a bulb set, a load box, a motor and an electronic load. The secondary system is a control system of an intelligent microgrid. The laboratorial intelligent microgrid system is simple in structure, convenient to build, low in cost, and easy to implement, and has important engineering application value on research of microgrid system energy management optimization and security and stability control strategies.

Description

technical field [0001] The invention belongs to the technical field of smart grids, and in particular relates to a laboratory smart micro-grid system based on various distributed power sources. Background technique [0002] In order to make up for the shortage of large-scale centralized power generation and transmission, distributed power generation and micro-grid systems that have emerged in recent years have received more and more attention. The micro-grid system combines the power generation system, energy storage system, and load. Through the cooperation of related control devices, it can provide users with electric energy and heat energy at the same time, and can support the large power grid in a timely and effective manner. It not only solves the problem of large-scale access to distributed power generation systems, but also gives full play to the advantages of distributed power generation systems, and brings other benefits to users. [0003] At present, my country ha...
