Description
technical field [0001] The invention relates to the field of photovoltaic distribution network technology, in particular to an intelligent analysis system and method for distributed photovoltaic power sources in a distribution transformer area. Background technique [0002] Nowadays, distributed photovoltaic power generation technology is a very promising new power generation technology in our country. It uses solar energy, which is environmentally friendly and renewable, to generate electricity. With the rapid development of our country's economy and the progress of society, people are increasingly inseparable from electric energy, which has become an indispensable part of people's lives. However, most of our country has been using coal, natural gas, petroleum and other chemical fuels For power generation, these fuels are non-renewable resources, so if you continue to use these resources for a long time, they will be exhausted one day. Not only that, but they also have a bi...
