Is energy storage a new regulatory resource?

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 .

Does a regional grid improve frequency performance?

A regional grid with a TPU and a hybrid ES station is used to validate the effectiveness of the proposed strategy. The results show that the FR resources are stimulated to improve their performance, and thus, the frequency performance of the system is improved by the proposed strategy. 1. Introduction

Is Fr Power rated in regional power grid?

Assuming that the bid FR power of each ES unit is its rated power in the regional power grid.

What is the FR cost of a regional grid?

The FR cost of a regional grid is composed of the TPU costs F1 and the ES station costs F2. The TPU output and the ES station output are decision variables. For the TPU, the FR leads to power deviation from the optimal operating point, which in turn leads to increased wear and tear.

Do energy storage stations improve frequency stability?

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.

What are the premise of meeting the grid regulation demand power?

Under the premise of meeting the grid regulation demand power, the rated power and the rated climbing rate of the TPU, the rated power, rated climbing rate, and the SOC limitation of the ES station are considered as constraints, shown as (4) where is the FR demand power of the z -th AGC command. is the time interval between two AGC commands.
