【摘要】：通辽市位于内蒙古自治区东部,拥有丰富的太阳能资源,区位优势明显,开发条件优越。“十二五”期间,在国家鼓励新能源相关政策出台,以及自治区"8337"发展思路,太阳能光伏发电得到了较快发展,承爆发式增长趋势。截止2015年5月,通辽电网光伏电站投产7座,总装机容量30万千瓦。随着光伏爆发式发展,然而光伏电站类型复杂,其带来的控制、送出和消纳问题,对电网运行和稳定特性影响深刻,因此为保证光伏可持续发展,保证发电企业、供电公司和地方政府共同利益,更好的服务地方经济发展,光伏电站并网管理研究是势在必行的。本文首先对并网光伏电站进行动态数学建模及并网光伏电站稳定分析,进一步考虑了最大功率跟踪控制对系统稳定性的影响,提出了光伏电站并网运行稳定性判据。此外,分析了通辽地区光伏电站并网管理评价的关键因素,构建了基于管理成效、经济效益、社会效益的三级评价指标体系,并分析了各指标的主要涵义,并提出基于德尔菲法协同主成分分析法对光伏电站并网管理指标体系模型。其次,详细分析了内蒙古和通辽电网的电网状况、负荷预测、太阳能资源情况,并通过实地调研研究通辽电网光伏电站接入情况。再者,进行了光伏电站接入通辽电网后的稳定性分析——以霍林郭勒市光伏电站为例。明确了通辽扎鲁特旗20MW光伏项目接入霍林郭勒地区的系统方案,在潮流方式计算的基础上,进行光伏电站接入电网后的过载分析、同步稳定分析、电压稳定分析。在此基础上,基于德尔菲法协同主成分分析法分析通辽光伏并网管理体系,从27个指标中汇总筛选出影响光伏并网的10个主成分,得出该项目在并网管理、经济发展、社会性三方面的综合效益。并且,提出光伏电站并网的优化管理策略,包括光伏电站规划管理、发电计划管理、并网运行技术要求、并网管理、运行调度管理、光伏电站工程建设质量管理以及建设运营监管等方面。同时,为切实解决光伏电站并网后影响系统安全、稳定、经济运行的核心问题,针对未来通辽光伏电站的建设及接入,提出了光光伏电站出口管理、建立光伏电站一图一表、并网关键技术研究等具体建议。
[Abstract]:Tongliao city is located in the eastern part of the Inner Mongolia Autonomous Region, has abundant solar energy resources, location advantages, development of favorable conditions. "12th Five-Year", issued in the country to encourage new energy related policies, as well as the autonomous region "8337" development ideas, solar photovoltaic power generation has been rapid development, the explosive growth trend. By the end of May 2015, the Tongliao power grid photovoltaic power station production of 7, the total installed capacity of 300 thousand kilowatts. With the explosive development of photovoltaic photovoltaic power plants, but the type of complex, control, sending and dissolve the problem, a profound impact on the power grid operation and stable characteristics, so as to ensure the sustainable development of photovoltaic power generation enterprises, to ensure the power supply, the common interests of the company and the local government, better service the development of local economy, management of grid connected photovoltaic power station is imperative. Firstly, grid connected photovoltaic power plant dynamic mathematical modeling and grid light Analysis of photovoltaic power station is stable, the maximum power tracking control effect on system stability, photovoltaic power grid connected operation stability criterion is proposed. In addition, the analysis of the key factors to evaluate grid PV power plant management in Tongliao, based on management, economic benefits, social benefits three level evaluation index system, and analyzed the main the meaning of each index, and puts forward the analysis method of grid PV power plant management index system model. Based on principal component collaborative Delphi method secondly, detailed analysis of the situation of Inner Mongolia power grid, Tongliao power grid and the load forecasting, solar resources, and through the investigation on Tongliao grid photovoltaic power station access. Moreover, the stability analysis of photovoltaic Tongliao power grid power station access after taking Huolinguole City photovoltaic power plant as an example. The Tongliao Zhaluteqi photovoltaic project by 20MW System into the region Huolinguole in power flow calculations, based on the analysis of overload mode, grid connected photovoltaic power station after the synchronization, stability analysis, voltage stability analysis. Based on the analysis of network management system of Tongliao photovoltaic and co principal component based on Delphi method, from the 27 indicators in summary selected. 10 the main components of PV, the economic development projects in the grid management, comprehensive benefit three aspects of social. And put forward the optimal management strategy for grid connected photovoltaic power station, including the planning and management of photovoltaic power plants, power generation project management, requirements, operation technology of grid grid management, operation management, quality management and construction of photovoltaic power plants the construction and operation of supervision. At the same time, in order to solve the grid PV power plant after the impact of system safety, stability and economic operation of the core question, for the future of Tongliao light The construction and access of volt power station put forward some specific suggestions on the export management of photovoltaic power stations, the establishment of a chart and one chart of the photovoltaic power station, and the research on the key technology of the grid.
