摘要
为解决分布式光伏接入电网时可能遇到的困难,提出一种考虑分布式光伏接入的大用户供电方案设计方法,即报装容量较大的大用户往往具备较好的光伏建设条件,在其供电方案设计时就应考虑未来可能建设的光伏项目,预留光伏接入位置、线行通道;分析因光伏并网可能造成的影响,必要时修改接线方式,使供电方案的设计更趋科学合理。以广东某用户供电方案设计为算例,通过仿真分析计算,验证了所提方法的可行性和合理性。
For solving probable difficulties of accessing distributed photovoltaic in power grid,a kind of design method of power supply scheme for large users considering distributed photovoltaic access was proposed which was to consider photovol-taic projects probably to be constructed in the future when designing power supply scheme,obligate photovoltaic accessing position and line channels,due to large users with large installation capacities were provided with better photovoltaic con-struction conditions. Possible affects by photovoltaic integration were analyzed and it was proposed to modify connection modes in necessity for making design of power supply scheme more scientific and reasonable. Taking design of power supply scheme for some user in Guangdong as an example,the simulating analysis and calculation verifies feasibility and reasonabili-ty of the proposed method.
