中文摘要： 近年来越来越多的太阳能光伏发电系统以分布式发电形式并入电网，这些光伏并网发电系统是根据本地负载和环境等要求进行设计和控制的，它们之间没有交互和通讯，只靠本身的传感器获取周边的信息；如何实现它们的协调控制，是本项目研究的重点。本项目针对无显式通讯分布式光伏并网发电系统，分析高渗透率下系统分布位置和容量的影响机理；根据群集智能的思想，研究基于博弈理论的多智能体协调控制方法，寻求电网稳定运行的纳什均衡点；然后研究外界环境变化对电网稳定性和电能质量的影响，分析电网稳定域和稳定方法；继而综合考虑电能质量，进一步研究电网电压、无功和谐波的多目标协调优化方法；通过仿真和实验验证控制算法的有效性和实用性。本项目的研究将为提高光伏并网发电系统可靠性、稳定性和市场竞争力奠定基础，同时为分布式发电技术的发展提供理论基础。

英文摘要： In recent years, there has been an increasing number of distributed photovoltaic (PV) generators paralleled in the power grid. These PV generators with different owners are designed and controlled locally according to load demand, environmental requirements, PV panel and battery capacities. There is no explicit communication among the distributed PV generators. The distributed PV units can only get neighboring information through the self-sensors. Therefore, how to realize the cooperative control for the distributed PV generators is the main research point in this project. This project focuses on distributed PV grid-connected generation system without explicit communication. It is analyzed that the effect between power grid and PV systems. Based on the swarm intelligence theory, the stability of high permeability of PV generators is analyzed. The cooperative control method for distributed PV generation system without explicit communication is investigated based on multi-agent game theory. Then, regarding the external environment changes, it is studied that the stability of distributed power generation system and related power quality in grid. Meanwhile, considering the power quality, multi-objective optimization method for voltage, reactive power and harmonic in distributed PV power system is further examined. T
