The conceptual framework of future power grid incorporates self-automated power flow components. It incorporates high penetration of intermittent renewable energy and variable users' load demands. To establish an efficient real-time power flow mechanism, a realization of the exact amount of energy generation and consumption is inevitable. Hence, we propose a novel framework of a smart micro-grid (SMG),...
This paper proposes an enhanced three step design framework for microgrids designed with fixed capacity shortages (CS) that optimizes cost using load prioritization, battery thresholds and predicted solar data in the design phase instead of operational phase to reduce capital expenditure. This is achieved through reduction in battery size. The framework uses HOMER to model microgrids that are cost...
Growth in the electric vehicle and renewable energyindustries has created a corresponding interest in energy storagesystems. Since storage systems have finite reserves, new toolsare required in order to properly examine and optimize theireffects in power system studies. Time stepped power flow analysesin particular are crucial to understanding the implications ofincorporating storage into a system...
This paper presents optimal sizing, modeling and performance analysis of a standalone PV/Wind/Battery Hybrid Energy System (PWB-HES) for an off-grid residential application in Ansons Bay, Tasmania, Australia. The aim of the study is to find the optimal size of the photovoltaic (PV) panel, wind generation system (WGS) and battery storage (BS) that can satisfy the varying load demand throughout the...
This paper describes a modeling of a Microgrid using real time simulation platform and presents the results of the simulation. The Microgrid under study consists of a Photovoltaic (PV) system as an example of an unreliable resource and a battery representing an energy storage. The modeling approach and the study analysis performed are described. The model and operation scenarios have successfully...
The global warming, air pollution and climate change are danger signals that all is not too well with environment. The main causes of these adverse effects are conventional energy generation. Renewable energy has great capacity to usher in universal energy access. Today, about 400 million people in India have no access to commercial electricity. Energy generations from renewable sources are the best...
The goal of this paper is to investigate the application of nonlinear control technique to a multi-input multi-output (MIMO) nonlinear model of a wind energy battery-storage system using a permanent magnet synchronous generator (PMSG). The challenge is that the system should operate in both grid-connected and standalone modes while ensuring a seamless transition between the two modes and an efficient...
The research object refers to micro-grid which contains wind turbine (WT), Photo Voltaic (PV), storage and other micro-sources. Considering system operation modes, network restrictions and construction & operation costs, through coordinated control between battery storage and other micro-sources, the optimal battery capacity configuration scheme is proposed aiming at maximum economic benefits...
