摘要:當前随着我国光伏需求的持续上升以及电力市场经济的快速增长,化石生物燃料再生能源日益匮乏和日渐枯竭,能源危机和生态环境资源污染等社会问题也越来越严重,光伏电力行业都面临着严峻的新挑战,为解决传统化石燃料发电所面临的问题,在“低碳”的号召下,源于分布式光伏风力发电的小型智能微电网应运而生。微电网灵活的经营运作管理方式及其所配套的高质量电网供电运输服务都必定离不开一套科学完善的经营控制管理体系,所以关于我国微电网经营管理策略的深入探讨必须具有很强的理论指导性。本文主要探索光储系统在电力系统应用的价值,以现场光储系统联合驱动微电网技术工程建设为主要研究背景,在完成总体控制策略的相关技术理论研究及其系统建模仿真的基础上,将这一技术控制策略成功地应用于现场的微电网。该项重点技术是国内外首个面向采用光伏电池发电、储能混合动力车和蓄电池组的新型储能微电网国家试点研究项目,对于新型微电网在系统运行过程中的控制应用做出有效的技术探索和创新尝试,为其用于后续的新型微电网的深入研究应用和发展奠定重要的理论和实践基础。

Abstract: With the continuous rise of my country's photovoltaic demand and the rapid growth of the electricity market economy, fossil biofuel renewable energy is increasingly scarce and depleted, and social problems such as energy crisis and ecological environmental resource pollution are becoming more and more serious. The photovoltaic power industry is Facing severe new challenges, in order to solve the problems faced by traditional fossil fuel power generation, under the call of "low carbon", a small smart microgrid derived from distributed photovoltaic wind power generation came into being. The flexible operation and management methods of microgrid and its supporting high-quality grid power supply and transportation services must be inseparable from a set of scientific and complete operation control and management system, so in-depth discussion on the management strategy of my country's microgrid must have a strong Theoretical guidance. This paper mainly explores the value of optical storage system in the application of power system. It takes the field optical storage system to drive the construction of microgrid technology as the main research background. On the basis of completing the relevant technical theoretical research of the overall control strategy and system modeling and simulation, This technology control strategy was successfully applied to the on-site micro-grid. This key technology is the first domestic and foreign national pilot research project for a new type of energy storage microgrid that uses photovoltaic cells for power generation, energy storage hybrid electric vehicles and battery packs. It is effective for the control application of the new microgrid during system operation. Technological exploration and innovative attempts have laid an important theoretical and practical foundation for the in-depth research, application and development of the subsequent new microgrid.
