Abstract

Estimation of virtual inertia in grid-connected renewable energy resources is the primary challenge faced by researchers in the field of load frequency control in the modern power system. The main objective of this study is to review the strategies of virtual inertia, which are used to compensate for the required inertia to reduce frequency deviation. The stability issue regarding virtual inertia estimators integrated with power system is also a challenge, which is reviewed in this study. A modified power system based on an inertia estimator with a compensator is suggested using the modified techniques presented in recent manuscripts. The most published manuscripts in the field of the following scenarios: (i) load frequency control with renewable energy resources and (ii) load frequency control with virtual inertia are statistically analyzed and the high cited manuscripts related to these research gaps are discussed in detail. The new direction of this review study is suggested to continue improving the virtual inertia estimators by authors.

间歇性可再生能源对电力系统的虚拟惯性策略综述

并网可再生能源的虚拟惯性估计是现代电力系统负荷频率控制领域研究人员面临的主要挑战。本研究的主要目的是回顾虚拟惯性的策略，用来补偿所需的惯性，以减少频率偏差。将虚拟惯性估计器集成到电力系统中的稳定性问题也是一个挑战，本文对此进行了综述。本文提出了一种基于惯性估计器和补偿器的改进电力系统。统计分析了基于可再生能源的负荷频率控制和基于虚拟惯性的负荷频率控制两种情况下发表最多的论文，并详细讨论了与这些研究空白相关的高被引论文。作者提出了今后研究的新方向，即继续改进虚拟惯性估计器。
