With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
A multi-module FR power optimization strategy is proposed in this paper. The power rolling distribution module realizes the FR power distribution between TPUs and ES stations with the minimum cost and the redistribution between the ES units based on comprehensive efficiency.
(3) The power distribution strategy based on comprehensive efficiency provides a more reasonable power and compensation revenue distribution scheme for ES units, increasing the net FR benefits of the ES station and enhancing the FR performance of the grid. It stimulates the ES unit to improve its efficiency and actively participate in FR response.
The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established. The multi-level power distribution strategy based on comprehensive efficiencies of energy storage is proposed. With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system.
