چکیده

Abstract Firstly, the basic equivalent model of inverter parallel connection is briefly introduced, and then working principle sag control described. The has a certain effect on regulation reactive power active power, but when line impedance not equal, distribution among inverters cannot be reasonably dispatched distributed. robustness system verified.

Load Frequency Control Based on Improved Fuzzy Controller in the Microgrid with Thermoelectric Generator

The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....

Hierarchical MAS Based Control Strategy for Microgrid

Microgrids have become a hot topic driven by the dual pressures of environmental protection concerns and the energy crisis. In this paper, a challenge for the distributed control of a modern electric grid incorporating clusters of residential microgrids is elaborated and a hierarchical multi-agent system (MAS) is proposed as a solution. The issues of how to realize the hierarchical MAS and how ...

Improved Control Strategy for Microgrid Ultracapacitor Energy Storage Systems

Ultracapacitors (UCs), with their features of high power density and high current charge-discharge, have become the best choice for dynamic power compensation to improve the stability of microgrids and are increasingly being applied in microgrids. This paper presents the control of an energy storage system (ESS) based on ultracapacitors in the context of grid-connected microgrids. The ESS is co...

Delay Dependent H∞ Based Robust Control Strategy for Unified Power Quality Conditioner in a Microgrid

This paper proposes a novel robust control scheme based on delay-dependent H∞for unified power quality conditioner (UPQC) in a microgrid under the influence of the delay and parameter uncertainties. A new UPQC model considering the effects of the delay and parameter uncertainties is established. Then, the H∞ controller is designed based on the cone complementarity linearization (CCL) algorithm....

A New Control Strategy for Controlling Isolated Microgrid

Microgrid control in isolated mode is a highly important subject area. In the present paper, a new method is used for controlling the isolated microgrids. This method was used based on the classification of the microgrids into two groups, namely fast-dynamic (battery and flywheel) and slow-dynamic (diesel generator, electrolyzer, fuel cell). For the microgrid components with fast dynamics, a se...
