The invention discloses an intermittent renewable energy layered partition grid-connected planning method which is applicable to line extension scheme making for layered partition access points and power grids of multiple intermittent renewable energy sources, and optimizing and planning the external transmission capacity of the active power. In the planning process, the access points and an optimal line scheme are respectively obtained based on different active power output capacity values. The production cost, reliability and the power output income index are evaluated through production simulation according to the optimal schemes. An active power output capacity, an intermittent renewable energy access point, and the optimal scheme decision of the power grid line expansion scheme are achieved through a TOPSIS method on the basis of the construction cost and the evaluation indexes.
Description
technical field [0001] The invention relates to the technical field of power grid planning, in particular to a hierarchical and partitioned grid-connected planning method for intermittent renewable energy. Background technique [0002] With the rapid development of intermittent renewable energy such as wind power and photovoltaics in my country, the intermittency and volatility of this type of energy will have a significant impact on the operation and planning of the power grid. Therefore, it is of great importance to consider its impact in power grid planning. necessity. [0003] Because the large-capacity intermittent renewable energy in the grid system has different access voltage levels, access areas, and specific access points, its impact on the operation of the grid system will also be different, which involves the operation of the grid. Safety, reliability and economics, therefore, hierarchical zonal access point optimization for intermittent renewable energy sources ...
