Abstract

The invention discloses an evaluation method based on new energy power generation grid-connected coordination cost, and the method carries out the modeling analysis of various factors affecting the power grid coordination operation cost, builds a function relation through external environment parameters and operator operation parameters, calculates a correlation coefficient, and finally obtains a calculation method based on the new energy power generation grid-connected coordination cost. The economic pressure of power grid operation is judged by calculating the comprehensive evaluation value of the adjustment cost, so that the economic influence of a certain type of power supply in the power grid on other power supplies can be accurately evaluated under the condition of ensuring the safety of the power grid operation, the power grid is helped to construct a power transaction mechanism, and the economic cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power grid coordination control, in particular to an evaluation method for grid-connected coordination cost based on new energy power generation. Background technique [0002] As the proportion of wind and photovoltaic new energy power generation continues to increase, a trend of wind power photovoltaic grid-connected coordinated power supply has formed, and different proportions of wind power photovoltaic grid-connected have resulted in differences in power supply capabilities of the grid. Grid-connected coordinated power generation costs are evaluated. At present, most of the researches focus on the single use of wind power or solar power, and seldom use the combination of wind power and photovoltaic to complement each other, without comprehensively considering the output of wind power and photovoltaic and the proportion of wind power and photovoltaic in the system power generation. Therefore, the pres...
