Abstract

Various power generation technologies, such as wind turbines and solar power plants, have been increasingly installed in renewable energy projects as a result of rising demand and ongoing efforts by global researchers to mitigate environmental effects. The sole source of energy for such generation is nature. The incorporation of the green unit into the power grid also results in volatility. The stabilization of frequencies is critical and depends on the balance of supply and demand. An efficient monitoring scheme called Load Frequency Monitoring (LFM) is introduced to reduce the frequency deviation from its natural state. Specific energy storage systems may be considered to improve the efficiency of the control system. The storage system contributes to the load rate, peak rushing, black start support, etc., in addition to high energy and rapid responsive features. A detailed study of different power storage systems, their current business scenario, and the application of LFM facilities, as well as their analysis and disturbance, is presented in this paper. According to the literature analysis, the current approaches can be divided into two categories: grid and load scale structures. This article also distinguishes between the organized aggregate system and the uncoordinated system control scheme, both of which have advantages and disadvantages in terms of technology.

Highlights

  • One method of this type is the management of frequencies; the Battery Energy Storage Unit (BESU) has been used for decades

  • The findings show that the Load Frequency Monitoring (LFM) system develops successfully these frequency management techniques

  • Energy storage is essential to improve the power quality. It provides substantial technical and economic support for the stability of the system. This procedure can be implemented with a wide range of storage units managed through the LFM utility

Summary

Introduction

Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Renewable energy sources have increased to a high level, challenging the generation-demand balance [6]. To maintain this balance, the power structure, has used three different control schemes. The LFM faces some economic and practical challenges due to partial loads [9,10,11,12] These include high operation and maintenance costs and reduced efficiency. The paper is organized as follows: Section 1 presents the study and comparison of different energy storage technology technical features, followed by Section 2, which presents scenarios of management of energy storage in various parts of the world, and Section 3, which presents energy storage system (primarily battery storage) applications and control strategies in the frequency regulation process.
