Dispatching of wind farms using battery energy storage
In this paper, a STATCOM interfaced battery energy storage system (BESS) is considered for smoothing intermittent power output of a large wind farm so that it can be dispatched. The main advantage of the system is that it can inject both real power (by charging/discharging the BESS) and the reactive power to the system. The paper investigates the main design issues related to BESS – the control ...

Split capacitor VSC-based voltage and frequency controller for a stand-alone wind power generation
This paper presents an investigation on a small scale, stand-alone wind power generating system employing a capacitor excited squirrel cage asynchronous generator. A solid state controller is used to regulate the generated voltage and frequency to constant values at the generator terminals under various dynamic conditions such as varying wind speeds and varying consumer loads along with its ...

STATCOM based voltage-frequency regulation for SEIG driven by an uncontrolled speed turbine
This article presents the analysis and the control of a stand-alone self excited induction generator (SEIG) intended for rural applications. SEIG along with the STATCOM with battery energy storage (BES) in its DC side makes it possible to control the terminal voltage and frequency during rotor speed and load variation. Constant frequency control is carried out by the load angle 'δ', without rotor ...

A control method to improve the efficiency of a soft–switching non–isolated bidirectional DC–DC converter for hybrid and plug–in electric vehicle applications
Hybrid energy storage system (HESS) can be adopted in hybrid, plug–in hybrid, and pure electric vehicles (HEV, PHEV, and EV), where a bidirectional DC–DC converter (BDC) is used to connect batteries and ultra–capacitors. The efficiency improvement of the BDC is beneficial to increase the efficiency viability of HESS. Due to ZVS, high efficiency can be obtained at heavy load operations while the ...

Control and small-signal analysis of battery and supercapacitor hybrid energy storage systems
This paper is devoted to control strategies for an active battery and supercapacitor hybrid energy storage system using the master-slave control scheme, where the charging and discharging currents of the supercapacitor are dependent on that of battery and the current sharing ratio depends upon the load conditions. A small-signal model is proposed, which considers the variations in the currents of ...

A frequency control method for isolated photovoltaic-diesel hybrid power system without smoothing renewable power variations
In this paper, a frequency control method is introduced for photovoltaic-diesel hybrid system by using a load estimator and an energy storage system. The proposed method is compared with an energy storage based conventional control method and with a fuzzy based frequency control method. Simulation results show that the proposed method is feasible to reduce the frequency deviations of the isolated ...

Design, control and performance analysis of a standalone solar–PV energy generating system
This paper presents the design, control and performance of a low power standalone solar–photovoltaic (PV) energy generating system. The system includes a maximum power point tracking (MPPT) controller along with a full bridge DC–DC converter, an energy storage system and a voltage source inverter (VSI). The detailed design and modelling of the system components are given with incremental ...

Comparative performance of BESS and SMES in distribution network to improve power quality
The FACTS devices, like STATCOM, are becoming a part of the modern power system to improve the power system operation and power quality problems. Integrating the battery energy storage system (BESS)/superconducting magnetic energy storage (SMES) across the dc bus of the STATCOM can provide effective modulation of the real and reactive power. The dynamics of each of these differ because of their ...

Battery Management for Large-Scale Energy Storage (Part 1)
Battery Management and Large-Scale Energy Storage While all battery management systems (BMS) share certain roles and responsibilities in an energy storage system (ESS), they do not all include the same features and functions that a BMS can contribute to the operation of an ESS. This article will explore the general roles and responsibilities of all battery management systems, and will also ...
