【摘要】：基于風光儲的分布式發(fā)電系統(tǒng)是當前研究的熱點,但目前大多數(shù)的研究僅限于軟件建模仿真階段。因此為當前的研究提供更接近實際系統(tǒng)的分布式發(fā)電半實物仿真平臺具有重要意義。為了對分布式發(fā)電系統(tǒng)的控制策略進行驗證,本文將分布式發(fā)電系統(tǒng)和半物理仿真平臺進行結(jié)合,建立了分布式發(fā)電系統(tǒng)半物理仿真平臺。針對該平臺的設計,本文從以下幾個方面開展研究工作。(1)設計了分布式發(fā)電系統(tǒng)半物理仿真平臺的電氣結(jié)構(gòu),網(wǎng)絡拓撲結(jié)構(gòu),對組成平臺的光伏發(fā)電單元、鋰電池儲能單元、超級電容儲能單元、風力發(fā)電單元、模擬負載單元、能量管理控制器、監(jiān)控服務器等進行了設計及設備選型。(2)針對分布式發(fā)電系統(tǒng)半物理仿真平臺的風力發(fā)電部分,設計了基于DSpace的電動機、發(fā)電機、變流器等風力發(fā)電半實物仿真平臺;開發(fā)了基于DSpace的風速模型、風力機傳動模型,實現(xiàn)了風力發(fā)電平臺的半實物仿真平臺。(3)實現(xiàn)了基于MATLAB的能量管理算法在分布式發(fā)電系統(tǒng)半實物仿真平臺上的快速驗證,為能量管理算法的驗證提供了平臺。同時開發(fā)了基于LAMP架構(gòu)的半實物仿真平臺的監(jiān)控系統(tǒng),實現(xiàn)了系統(tǒng)的本地和遠程監(jiān)控。(4)對分布式發(fā)電系統(tǒng)半實物仿真平臺的能量管理功能進行了驗證,包括光伏發(fā)電單元的最大功率跟蹤功能及定功率發(fā)電功能、風力發(fā)電單元的功率最大功率跟蹤及定功率發(fā)電功能、儲能單元的P/Q功能模式和V/f功能模式。基于上述的研究,本文完成了分布式發(fā)電系統(tǒng)半物理仿真平臺的設計搭建,并通過仿真及實驗驗證了各個模塊的可行性以及能量管理策略對風力發(fā)電模塊、光伏發(fā)電模塊、儲能模塊的實時調(diào)度,為能量管理策略的研究提供了快速高效的驗證手段。
[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.

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.
