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.
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.
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 .
Thus, it is necessary to validate and simulate the power facility protection system using a relay coordination approach. The input feasibility of the generator for the frequency regulation (FR) of the operational ESS is also validated through detailed analysis studies including power flow, short circuit and relay coordination analysis.
In order to improve the frequency stability, minimize FR control costs, and rationalize the revenue allocation between FR resources, a double-module FR power optimization strategy is proposed considering the cost, performance, and revenue of TPU and ES. The significant innovations of this paper can be described as follows:
The proposed strategy I changes the power distribution ratios dynamically to take full advantage of each regulatory resource. For example, when the AGC commands surge at the 64th or 102nd minute, only the ES station with better response performance outputs power to meet the FR demands as soon as possible.
