摘要：

This paper assesses the value of bulk grid-scale energy storage (GES) technologies in six electric power districts of China. The economic feasibility of GES under three different types of compensation mechanisms was analyzed. Based on a careful investigation of Chinas existing power system, a unit commitment model that comprehensively reflects the production costs (including reduction of fuel consumption, grid loss, ancillary services and so on) of the entire power grid has been proposed. The benefits of GES can be obtained by comparing the production costs of two different scenarios: with and without GES. Results show that under the current scheduling methods and compensation mechanisms, in most provinces in China, the energy storages revenue is lower than the value that it brings.
