Study on market mechanisms for participation of small-scale hydropower clusters in electricity energy and ancillary services

Abstract

The problem of large-scale distributed new energy consumption is highlighted under the double carbon target. Based on the existing distributed small hydropower and local hydrological and geographical conditions, the pumping-storage linkage function of distributed small hydropower can be realized through small-scale transformation according to local conditions, which can significantly reduce the construction cost and improve the profitability of the power station. The development of small hydropower to pumped storage can effectively enhance the flexible regulation capacity of the power grid. Based on an analysis of the investment environment, profitability and option characteristics of small hydropower to pumped storage projects, this paper conducts a study on the operational mechanism of hydropower participation in the electricity energy market and auxiliary services market to provide support for small hydropower to pumped storage investments in the new situation.
