Description

technical field [0001] The invention relates to a system in the field of distribution network planning, in particular to an auxiliary system for design, analysis and evaluation of photovoltaic power generation access distribution network schemes. Background technique [0002] As the main means of utilizing solar energy, photovoltaic power generation is of great significance to optimize the energy structure, promote energy conservation and emission reduction, and achieve sustainable social and economic development. With the successive promulgation of relevant policies and technical standards, domestic grid-connected photovoltaic capacity has shown a sharp upward trend in recent years. The large-scale distributed photovoltaic access to the distribution network will have an impact on many aspects such as the planning and operation of the traditional distribution network. The new type of active distribution network with double-terminal uncertainty of the power supply makes the ...
