This paper develops a three-step process to assess the resource-adequacy contribution of energy storage that provides frequency regulation. First, we use discretized stochastic dynamic optimization to derive decision policies that tradeoff between different energy-storage applications.
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.
The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
As a new type of flexible regulatory resource with a bidirectional regulation function [3, 4], energy storage (ES) has attracted more attention in participation in automatic generation control (AGC). It also has become essential to the future frequency regulation auxiliary service market .
Energy storage frequency regulation stations have evolved from technical novelties to economic powerhouses. As grids worldwide decarbonize, these systems will play a crucial role in balancing
