The embodiment of the invention discloses a wind power consumption assessment method and device, which carries out assessment based on an electric power system including wind power and battery energystorage, wherein the battery energy storage can suppress the fluctuation of the wind power. The method comprises the steps of modifying a load curve under the condition that the combined output of thewind power and battery energy storage reaches the optimal, carrying out simulation analysis on a thermal power unit in the electric power system according to the modified load curve, and finally carrying out multi-dimensional assessment analysis on the wind power consumption from three aspects such as the stability, the reliability and the economy according to the optimized combined output of thewind power and battery energy storage and the simulation analysis of the thermal power unit, thereby enabling assessment for the wind power consumption to be more comprehensive, and improving the accuracy of wind power consumption assessment.
Description
technical field [0001] The present application relates to the technical field of power system operation evaluation, in particular to a wind power accommodation evaluation method and device. Background technique [0002] As a kind of clean energy, wind power has been put into use more and more. my country's wind power is characterized by a high degree of concentration, a large total scale, and is generally located far away from the load center, which makes it difficult to completely absorb wind power locally, and a large amount of wind power needs to be dispatched externally. However, wind power itself has the characteristics of randomness and volatility, which brings great difficulties to wind power dispatching and serious wind curtailment. Battery energy storage has the ability of rapid adjustment, which can stabilize the fluctuation of wind power, and is conducive to improving the ability of the power system to absorb wind power. In order to better guide the development ...
