Microgrids (MGs) contain a diverse mix of energy resources to provide safe and secure power to the consumers. Batteries are utilized in MGs for further energy security assurance as well as cost minimization. In this paper, an efficient approach is introduced for simultaneous energy management and optimal battery sizing to accomplish economic MG operation. Also, demand response programs are empl...

With the transition towards renewable energy underway, demand-side management together with local generation of is receiving growing attention. Optimizing self-consumption locally produced can not only have financial benefits for respective household or business (and improve their autarky from increasingly unstable markets), but also help grid stability against volatility some sources energy. I...

This research deals with the Non-Isolated Bidirectional Dc-Dc Converter (NBDC) control unit development for a smart power supply system using personal residential Photovoltaic-Power Conditioning Subsystem (PV-PCS), the results of circuits evaluation, and isolated PV-PCS operation connected battery storage (Electric vehicle storage etc.). The smart power supply system using the existing resident...

A spatial EMERGY model was created for Alachua County, Florida that was based on a generalized emergy diagram model for equal size (one-hectare) land area units. The diagram models each of the major inputs and storages of emergy that might occur in each land unit. A geographic information system (GIS) was used to create the model and study the spatial distribution of each EMERGY flow and storag...

This paper presents a C-rate control method for battery/supercapacitor (SC) hybrid energy storage system (HESS) to enhance the life cycle of battery in electric vehicles (EVs). The proposed HESS provides satisfactory power dynamic movements EVs (e.g., acceleration or braking) while keeping current within secure level prevent it from degradation. configurations conventional HESSs are often compl...

The proton exchange membrane (PEM) fuel cell is a green energy producer which converts chemical energy to electricity in high yield. Alternatively, the vanadium redox flow battery (VRB) is one of the best rechargeable batteries because of its capability to average loads and output power sources. These two systems are modeled by Nernst equation and electrochemical rules. An effective energy gene...

The proposed paper presents the DC/AC microgrid modeling using the Energy storage units and photovoltaic (PV) panels. The modal consists of a two stage power conversion. The power is supplied to the both DC and AC loads by this PV solar panels. The suitable way to explore the PV generation model is by using manufacturer datasheet. A bidirectional converter is connected to the battery storage sy...
