The present application provides a method for planning a renewable energy power generation and distribution network, which includes obtaining the rated capacities of hydropower stations, photovoltaic power stations and wind power stations respectively, and the number of hydropower stations, photovoltaic power stations and wind power stations is one or more. The power station distance and distance correlation coefficient between the hydropower station and the photovoltaic power station, the wind power station and the photovoltaic power station, and the hydropower station and the wind power station are respectively obtained. The wind direction angle correlation coefficients between the wind power station and the photovoltaic power station, and the hydropower station and the wind power station are respectively obtained. Based on the rated capacity, power station distance, distance correlation coefficient and wind angle correlation coefficient, calculate the power generation ratio coefficient of hydropower station, photovoltaic power station and wind power station. to plan. The power grid planning method provided in this application considers the relevant characteristics of renewable energy power generation output, optimizes the transmission capacity, reduces the investment in transmission lines, and improves the economy of power grid planning.
Description
technical field [0001] The invention relates to the technical field of renewable energy power grids, in particular to a planning method for renewable energy power generation and distribution networks. Background technique [0002] Renewable energy is energy from nature. It is inexhaustible and inexhaustible energy. It is a kind of energy relative to non-renewable energy that will be exhausted. It is harmless or minimally harmful to the environment, and the resources are widely distributed. , suitable for local development and utilization. The technology of applying renewable energy to power generation has gradually become a research hotspot. The renewable energy used for power generation and distribution mainly includes hydropower, wind power and photovoltaic power generation. [0003] Because most of the areas with abundant renewable energy, or areas with wind power and photovoltaic resources, are far away from residential power supply areas, in some local areas, power res...
