TL;DR: In this article, the authors mainly dealt with the modelling of distributed Generators such as solar cell, PEM (Proton Exchange Membrane) fuel cell and battery in steady state with power electronic interfaces and power flow management among these energy sources with or without grid.
Abstract: The growing demand for electrical power and the interruption of power supply has paved the way for realization of renewable based energy generation. Smart grid comes into picture which uses DG's there by managing the power demand and also reducing the environmental emissions. This paper mainly deals with the modelling of Distributed Generators such as solar cell, PEM (Proton Exchange Membrane) fuel cell and battery in steady state with power electronic interfaces and power flow management among these energy sources with or without grid. In this paper, the excess power is used to produce hydrogen to supply as input for fuel cell. The performance and results were reviewed in this paper with simulation results.

TL;DR: In this paper, an AC-linked hybrid wind/photovoltaic (PV)/fuel cell alternative energy system for stand-alone applications is proposed, where wind and PV are the primary power sources of the system, and an FC-electrolyzer combination is used as a backup and a long-term storage system.
Abstract: This paper proposes an AC-linked hybrid wind/photovoltaic (PV)/fuel cell (FC) alternative energy system for stand-alone applications. Wind and PV are the primary power sources of the system, and an FC-electrolyzer combination is used as a backup and a long-term storage system. An overall power management strategy is designed for the proposed system to manage power flows among the different energy sources and the storage unit in the system. A simulation model for the hybrid energy system has been developed using MATLAB/Simulink. The system performance under different scenarios has been verified by carrying out simulation studies using a practical load demand profile and real weather data.

TL;DR: In this article, the authors present the development of dynamic models for proton exchange membrane (PEM) fuel cells using electrical circuits, which have been implemented in MATLAB/SIMULINK and PSPICE environments.
Abstract: This paper presents the development of dynamic models for proton exchange membrane (PEM) fuel cells using electrical circuits. The models have been implemented in MATLAB/SIMULINK and PSPICE environments. Both the double-layer charging effect and the thermodynamic characteristic inside the fuel cell are included in the models. The model responses obtained at steady-state and transient conditions are validated by experimental data measured from an Avista Labs SR-12 500-W PEM fuel-cell stack. The models could be used in PEM fuel-cell control related studies.

TL;DR: A dynamic electrochemical model is presented for representation, simulation, and evaluation of performance of small size generation systems emphasizing particularly proton exchange membrane fuel-cell (PEMFC) stacks to guarantee a better analytical performance with respect to former ones with a consequent reduction in time and costs of projects using FCs as the primary source of energy.
Abstract: This paper presents a dynamic electrochemical model for representation, simulation, and evaluation of performance of small size generation systems emphasizing particularly proton exchange membrane fuel-cell (PEMFC) stacks. The results of the model are used to predict the output voltage, efficiency, and power of FCs as a function of the actual load current and of the constructive and operational parameters of the cells. Partial and total load insertion and rejection tests were accomplished to evaluate the dynamic response of the studied models. The results guarantee a better analytical performance of these models with respect to former ones with a consequent reduction in time and costs of projects using FCs as the primary source of energy. Additionally, this electrochemical model was tested for the SR-12 Modular PEM Generator, a stack rated at 500 W, manufactured by Avista Laboratories, for the Ballard Mark V FC and for the BCS 500-W stack.

Abstract: A photovoltaic array (PVA) simulation model to be used in Matlab-Simulink GUI environment is developed and presented in this paper. The model is developed using basic circuit equations of the photovoltaic (PV) solar cells including the effects of solar irradiation and temperature changes. The new model was tested using a directly coupled dc load as well as ac load via an inverter. Test and validation studies with proper load matching circuits are simulated and results are presented here.

TL;DR: For urban areas, a building integrated photovoltaic (BIPV) primarily for self-feeding of buildings equipped with PV array and storage is proposed, with an aim of elimination of multiple energy conversions.
Abstract: The utility grid challenge is to meet the current growing energy demand. One solution to this problem is to expand the role of microgrids that interact with the utility grid and operate independently in case of a limited availability during peak time or outage. This paper proposes, for urban areas, a building integrated photovoltaic (BIPV) primarily for self-feeding of buildings equipped with PV array and storage. With an aim of elimination of multiple energy conversions, a DC network distribution is considered. The BIPV can supply a tertiary building at the same time as PV array may produce power through a hierarchical supervision able to exchange messages with the smart grid and metadata. The hierarchical control is designed as an interface to expand the system ability for advanced energy management control having regard to the grid availability and user's commands. It consists of four layers: human-machine interface, prediction, cost management, and operation. The operation layer, implemented in an experimental platform, takes into account the grid supply power limits and constrains the DC load. The experimental results validate the approach that may be a solution for the future smart grid communication between BIPV and utility grid.
