[Abstract]:Distributed generation system based on wind storage is a hot research topic at present, but most of the researches are limited to software modeling and simulation stage. Therefore, it is of great significance to provide a distributed hardware-in-the-loop simulation platform for the current research. In order to verify the control strategy of the distributed generation system, this paper combines the distributed generation system with the semi-physical simulation platform, and establishes the semi-physical simulation platform of the distributed generation system. Aiming at the design of the platform, the research work is carried out in the following aspects. (1) the electrical structure, network topology, photovoltaic generation unit, lithium battery energy storage unit of distributed generation system semi-physical simulation platform are designed. Super capacitor energy storage unit, wind power generation unit, analog load unit, energy management controller, monitoring server and so on are designed and selected. (2) for the wind power generation part of the semi-physical simulation platform of distributed generation system, This paper designs the simulation platform of wind power generation based on DSpace, such as motor, generator and converter, develops wind speed model based on DSpace, wind turbine transmission model, and so on. The hardware-in-the-loop simulation platform of wind power generation platform is implemented. (3) the fast verification of energy management algorithm based on MATLAB is implemented on the hardware-in-the-loop simulation platform of distributed generation system, which provides a platform for the verification of energy management algorithm. At the same time, the monitoring system of hardware-in-the-loop simulation platform based on LAMP architecture is developed, and the local and remote monitoring system is realized.

It includes maximum power tracking function and fixed power generation function of photovoltaic unit, maximum power tracking and constant power generation function of wind power generation unit, P / Q function mode and Vr / f function mode of energy storage unit. Based on the above research, this paper completes the design and construction of the semi-physical simulation platform of distributed generation system, and verifies the feasibility of each module and the energy management strategy to wind power generation module, photovoltaic module through simulation and experiment. The real-time scheduling of energy storage module provides a fast and efficient verification method for the research of energy management strategy.
