Zusammenfassung:The invention provides an energy storage power station grid-connected point optimization method and system considering comprehensive sensitivity, and the method comprises the steps: carrying out the multi-scene sensitivity calculation of a node, which can be accessed to energy storage, of a power grid through considering a multi-dimensional index influencing the stability and economy of the system; the weights of corresponding indexes are selected according to the severity analysis of the problems of power grid line heavy load, network loss and voltage stability, so that multiple targets are converted into a single target, and the priority of energy storage grid-connected points is obtained. The method has the beneficial effects that an energy storage power station grid-connected point optimization scheme considering comprehensive sensitivity is given, factors such as delay of power transmission line construction, improvement of voltage stability and reduction of network active loss are considered, and the op
