The main purpose of this paper is to investigate the reduction of peak power consumption by using photovoltaic (PV) system. The decrease of the peak load in terms of demand side management is one of the important studies in smart grid. Renewable sources can be used to enhance the efficient use of the existing infrastructure. Technical and financial feasibility of PV used electricity peak power consumption...
This paper explores the problems of the averaging and interpolation of electricity consumption and distributed photovoltaic energy generation data on higher than hour resolution levels. The paper compares different interpolation methods, like linear and spline interpolation and discusses modelling approaches for the energy data reconstruction on the basis of minutely and hourly data. The results are...
This paper presents a collaboration between the University of Puerto Rico-Mayaguez (UPRM) and a community to establish Puerto Rico's first solar community in the southern part of the Island. This community-university collaboration is leveraging on well-organized community leadership and their efforts towards community self-reliance. Electrical engineering capstone design projects have been used as...
The energetic behaviour of ten nZEB built in Piemonte (region located in NW Italy) is analysed from experimental data. The energy consumptions are normalized for the weather conditions and size of the building, then the consumptions are compared with the design data. The data analysis shows that nZEB can be built in northern part of Italy and even if the real consumptions are slightly higher than...
As renewable energy becomes a larger fraction of the overall energy mix in the US, energy storage technology and its efficient deployment will be increasingly necessary. This work examines a small-scale microgrid which supplies renewable energy to a single building with both electric (battery) and thermal (hot-water) energy storage. The building contains a mix of apartments and one commercial kitchen,...
Buildings are important places and parts in the society. The conventional power supply of a building is AC power from the utility grid. As the growing penetration of renewable energy source and DC loads, it becomes practical and common for a building supplied by the distributed generators with DC power. Considering this unprecedented transition from the conventional AC building to the hybrid AC/DC...
Electric mobility is assuming a central role in the new world energy scenario where Renewable Energy Sources (RES) have increased their contribution to the electricity production, mainly due to the fact they are characterized by a reduced environmental impact; in the aforesaid context, Electric Vehicles (EVs) can play a significant role to facilitate the integration of RES into the power grid, also...
This paper deals with the investigation and economic evaluation of power supply systems in residential buildings with different shares of renewable energy in different years, different regulatory boundary conditions and cost digression estimations. A linear programming approach is selected for the determination of technical and economical capabilities of this energy system. By investigating and simulating...
In residential building sector, the provision of clean water is the one of primary need. The water pump used to do that matter. The technology for renewable energy source, i.e. Solar Water Pumping System (SWPS) will help the society in this sector to decrease the electricity consumption for providing clean water. The SWPS converts the solar energy into electricity. Then, the electricity used to activate...
Renewable Energy Sources (RES) have become an alternative form of energy in distribution networks. The 2010/31/EU Directive requires each new building to be highly energy efficient, with a large portion of its energy needs to be supplied by RES either locally or from a nearby source, from 2020 onwards. This paper emphasizes on the optimal utilization of the Photovoltaic (PV) energy produced in a building...
The Gulf Cooperation Council (GCC) countries have over 50% and 30% of global oil and gas reserves respectively and have therefore traditionally relied on fossil fuels to meet all their energy requirements. In recent years however there has been a realization to diversify their energy mix and tap on their rich solar energy potential. While buildings account for as much as 80% of the total national...
In this paper, a simulation platform for a smart microgrid configuration in a university campus is presented. The microgrid units include a photovoltaic installation, a battery energy storage system and an electricity energy management system. Sensitivity analysis is performed considering the impact of the developed model inputs, using as a test case one campus of the Democritus University of Thrace...
This paper develops a Net Zero Energy Building (NZEB) prototype with renewable energy integration applications. Most of the power generated by the utilities is consumed by the domestic loads and with urbanization; energy demand is continuously increasing in developing countries like India. To meet the ever growing demand, generation has to be increased and thereby transmitted over long distances which...
Electricity demand is rising rapidly due to the expansion of economy. This results in an increase of demand for electricity generation such as power plant fossil, hydro and nuclear. Every form of electricity generation has its strength and weakness. For example, fossil fuel power plants burn a significant amount of coal, oil or gas to produce electricity and produce large amount of greenhouse gas...
Under-frequency load shedding, rising electricity tariffs, environmental concerns and delays in constructing new power stations had plunged South Africa into darkness and constant need for load shedding. This has led consumers and producers alike to explore various energy generation options to assist the sector to meet its electricity demands whilst reducing their electricity needs. Renewable energy...
The European Commission published the climate and energy package “20 20 20” with the principle scope of reducing the greenhouse gas (GHG) emissions and increasing the production from renewable energy sources (RES). Electric Vehicles (EVs) contribute to lower the GHG emissions, as they produce no exhaust gas as opposed to internal combustion engine (ICE) vehicles. The present study is focused on the...
DC Microgrids (DC MG) present themselves as an obvious choice enabling integration of multiple renewable energy sources and distributed energy storage. This concept of DC electrification of homes in small communities is being explored in many parts of the world. Furthermore, typical household loads are increasingly becoming natively DC. In this paper, a community DC MG in an urban environment is analyzed...
In this paper, we first will report on the global situation regarding energy efficiency within buildings in Morocco, a promising sector that allows a real progress in many terms. Thereby we will take an interest in the flow of thermal energy for energy efficiency. For this we will use modeling tools such as TRNSYS to analyze energy efficiency gain from building materials. Then we will simulate the...
Africa's future is bright. Amid complex issues surrounding poverty, illiteracy, unemployment and energy deficiency, to name a few, the continent is also brimming with eager entrepreneurs and investors looking to take financial advantage of untapped sectors or under-fulfilled development needs. One such opportunity lies within shared solar energy. Solar energy has already proven itself to be a viable...
Electrification is the cornerstone of modern civilization. Humans have been investing in electrification for more than 140 years, since Thomas Edison invented the light bulb. With economic growth and technology development, most of the world (in developed countries) is supplied with reliable electrical power. But there are still nearly 1.3 billion people, most of them in developing Asia and Africa,...
