Electrochemical energy storage application scene evaluation method considering power grid operation constraint

The invention discloses an electrochemical energy storage power station application scene evaluation method considering a power grid operation constraint. According to the technical scheme, a power grid conventional unit, a pumped energy storage unit, new energy output, external power transmission and load data serve as input, power grid operation bottlenecks under different constraint conditions are quantified based on power grid operation constraint indexes, and power grid operation bottleneck analysis is performed by considering future power grid evolution characteristics and development trends. And on the basis of an identified operation bottleneck scene, electrochemical energy storage in different bottleneck scenes and other schemes are compared to eliminate economy of a bottleneck. The method has the beneficial effects that the method for searching the operation bottleneck of the power grid is provided, and the economic and feasible application scene of electrochemical energy storage is found through co
