With cell mobile phone devices becoming a basic part of life, the re-charging of cell mobile phone battery energy has always been a problem. The cell mobile phone devices differ in their talk-time and battery energy take a position by according to their producer and battery energy. All these mobile phones regardless of their producer and battery energy have to be put to renew after battery ener...

The electrification of public transport bus networks can be carried out utilizing different technological solutions, like trolley, battery or fuel cell buses. The purpose of this paper is to analyze how and to what extent existing bus networks can be electrified with fast charging battery buses. The so called opportunity chargers use mainly the regular dwell time at the stops to charge their ba...

In this paper, we describe methodologies for using portable, solar powered charging kiosks to provide mobile phone charging to communities following a disaster. We do not strive to provide a comprehensive alternative to grid power, rather we focus on charging mobile phones and other battery-powered devices. The small size of portable solar systems come with a trade-off: demand for power may exc...

This paper presents a novel multi-port DC/DC converter which is suitable to be used as the interface of hybrid renewable energy systems. The converter contains three unidirectional power flow ports which two of them are input ports and are connected to two independent energy sources while the third one is the output port that feeds a standalone load. Furthermore, the proposed converter contains...

In this paper, we study battery sizing for grid-connected photovoltaic (PV) systems. In our setting, PV generated electricity is used to supply the demand from loads: on one hand, if there is surplus PV generation, it is stored in a battery (as long as the battery is not fully charged), which has a fixed maximum charging/discharging rate; on the other hand, if the PV generation and battery disc...

This paper presents a preliminary economic study on the feasibility of using electric vehicles (EVs) to provide demand response, carried out as part of the GREEN Grid project. A mathematical model is developed to track the charge cycle of an EV battery, and this in turn provides estimates of the cost associated with battery life degradation under different scenarios. Three case studies are pres...

The enormous growth in the penetration of electric vehicles (EVs), has laid the path to advancements in the charging infrastructure. Connectivity between charging stations is an essential prerequisite for future EV adoption to alleviate users’ “range anxiety”. The existing charging stations fail to adopt power provision allocation and scheduling management. To improve the existing charging infr...

We demonstrate the use of model predictive control (MPC) for a microgrid with plug-in vehicles. A predictive model is developed based on a hub model of the microgrid, and the control is optimized for minimum generator fuel usage. A variety of horizons and levels of prediction error are used in the optimization. A new method to model expected load and error is presented based on radial basis fun...

ABSTRACT In this paper, a configuration of electric energy storage system for Hybrid Electric Vehicles has been proposed that consists of a small battery and ultracapacitor pack coupled to the vehicle bus through dc-dc converters. The entire system, together with necessary power electronics pack, has been modeled and a Model Predictive Controller (MP...

The main focus of this study is to design a novel stand alone PV-wind hybrid energy system for remote locations where grid extension is not feasible or is expensive. The hybrid PV-wind stand alone energy system shows higher reliability compared to wind or PV stand alone systems as wind and solar technologies complement each other. A Matlab/Simulink model of an integrated stand alone PV-wind hyb...
