Battery Energy Storage System for Aggregated Inertia-Droop Control and a Novel Frequency Dependent State-of-Charge Recovery

Modeling and Efficient Control of Microturbine Generation System With Battery Energy Storage for Sensitive Loads

Microturbine generation system is one of the most promising and a fast growing distributed generation sources. It is used in various applications thanks to high efficiency, quick start and high reliability. Combination of the microturbine and storage system (e.g. battery bank) is desirable selection to satisfy the load requirements under all conditions and hence the battery bank can play an imp...

A Control Strategy for Flywheel Energy Storage System for Frequency Stability Improvement in Islanded Microgrid

The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...

State of Charge Balancing Droop Control

Research on the Novel Charge-discharge System of Storage Battery

At present, the issue of low power factor and harmonic pollution in traditional charge-discharge system is serious, with the development of PWM rectifier technology, A novel main circuit topology of charge-discharge system with a three-phase voltage source PWM rectifier (VSR) and Bi-directional DC-DC converter are applied in this paper. It can be used as battery charging power supply, but also ...

A Novel Hybrid Droop-Isochronous Control Strategy for Microgrid Management

The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...
