Power Electronics and Energy Management for Battery Storage Systems

The deployment of distributed renewable generation and e-mobility systems is creating a demand for improved dynamic performance, flexibility, and resilience in electrical grids. Various energy storages, such as stationary and electric vehicle batteries, together with power electronic interfaces, will play a key role in addressing these requests thanks to their enhanced functionality, fast response times, and configuration flexibility. For the large-scale implementation of this technology, the associated enabling developments are becoming of paramount importance. These include energy management algorithms; optimal sizing and coordinated control strategies of different storage technologies, including e-mobility storage; power electronic converters for interfacing renewables and battery systems, which allow for advanced interactions with the grid; and increase in round-trip efficiencies by means of advanced materials, components, and algorithms. This Special Issue contains the developments that have been published b researchers in the areas of power electronics, energy management and battery storage. A range of potential solutions to the existing barriers is presented, aiming to make the most out of these emerging technologies

Modelling and control of a novel single phase generator based on a three phase cage rotor induction machine

This thesis develops the mathematical modelling and the closed loop control of a single-phase induction generator based on a three-phase cage rotor machine suitable for renewable energy conversion. Comprehensive dynamic and steady state models are developed in stationary ‘αβ’ reference frame and the accuracy is verified by comparing the theoretical results with the laboratory experimental results. Closed loop feedback regulator is designed to regulate the output voltage and frequency at the rated conditions

Managing household wind-energy generation

The use of intelligent-agent technology to aggregate wind-energy generation installed at several households and battery storage installed in similarly large number of households is described. This situation creates a virtual generator that can be dispatched on the electricity grid in a similar manner to to centralized generation. The purpose of aggregation is to sell renewable generation to the electricity network and at a price matching its value. Australia and other countries are also considering large-scale deployments of renewable-energy technology, such as solar photovoltaic generation or wind turbines for households. It is observed that changing technology, new market mechanisms, new funding mechanisms, and environmental concerns are making such deployments an attractive proposition. Some deployments are also taking the form of large farms of wind turbines or photovoltaic cells
