The invention relates to source network coordination technology, in particular to a method for calculating photovoltaic power generation accepting capability of a power grid of a high-altitude region. The method for calculating the photovoltaic power station accepting capability aiming at the power grid of the high-altitude region comprises the following steps of: 1) determining calculation conditions; 2) performing analysis aiming at the solar resource property of the high-altitude region and the power generation property of a photovoltaic power station; 3) performing calculation and analysis according to the peak regulating property of the power grid and the influence thereof on the photovoltaic power generation accepting capability of the power grid; and 4) obtaining the conclusion of the photovoltaic power generation accepting capability of the power grid of the high-altitude region. The method for calculating the photovoltaic power station accepting capability aiming at the running area of the power grid of the high-altitude region is applied in ensuring safe and stable operation between the scale photovoltaic power station and the power grid; and the method can be applied totechnical support for parallel photovoltaic power station accepting capability calculation of the high-altitude power grids of various voltage levels.
Description
technical field [0001] The invention relates to a source-network coordination technology, in particular to a method for calculating the receiving capacity of photovoltaic power generation in a high-altitude power grid. Background technique [0002] Energy is the basic driving force of the national economy. Under the pressure of the severe energy situation and the human ecological environment (climate warming), countries all over the world regard the development and utilization of sustainable clean energy as their future energy development strategy. Among them, solar energy has unique advantages such as abundant resources, no geographical boundaries, and cleanliness. And become one of the hot spots of people's attention. Solar photovoltaic power generation is a form of power generation that uses the photovoltaic effect principle of solar cells to directly convert solar radiation energy into electrical energy. Under the strong impetus of technological progress and regulati...
