We tend to imagine the infrastructure of electric power companies as power plants and power transmission lines. However, it has recently included services and solutions according to evolving technologies and changing governmental regulations. We have considered the services and infrastructure at an electric power company by analyzing the solutions that the electric power company would provide using...
Demand side management (DSM) has been studied to optimize the demand side of energy networks, which leads to maximization of social welfare. Methods of DSM usually require exchanges of true information used in the optimization process including private information, but in general market participants are not willing to reveal their private information. In a competitive society, each consumer's selfish...
Sustainable provision of off-grid solar electricity for Less Developed Countries (LDC) is a basic first step toward enabling a range of Beyond the Light Bulb initiatives. The off-grid electricity program of the Community Solutions Initiative (CSI), still at an early stage of development in several countries, is focused now on demonstrating sustainability and scalability. Initial steps to incubate...
In the last years, the rise in cost of fuel and the introduction of incentives from European countries led to a growth of interest for home systems that can locally produce, store and manage electric energy. In this scenario, a correct sizing, with respect to the expected consumption, of the energy production and storage devices is a key element for keeping acceptable the cost of the system. Here,...
Electric power trading has been adopted in many countries. In this paper, we focus on community-based electricity markets to reduce a demand of electric power and ensure an balancing supply of energy for renewable energy. The community can be defined as a domestic group of individual homes. We assume a community has a larger battery that can be shared by individual homes. In the real world, community-based...
In this paper, we propose a new model of demand response management for the future smart grid that integrates plug-in electric vehicles. A price scheme considering fluctuation cost is developed. We consider a market where users have the flexibility to sell back the energy generated from their distributed generators or the energy stored in their plug-in electric vehicles. A distributed optimization...
For the Dutch Ministry for Infrastructure and the Environment data of plug-in vehicles was collected. Data concerning fueling and charging of plug-in vehicles is collected from lease companies, a fuel-pass company, and the charging infrastruture organisation. More than 10% of the total Dutch plug-in fleet is covered. The electricity data is insufficient to derive a real-world electricity use, e.g...
From the years 2009–2012 about 330 battery-electric passenger cars (M1) and light-duty vehicles (N1) were operated in a large-scale demonstration project in Hamburg, Germany's second largest city (pop. 1.8m). The vehicles were used in commercial fleets and businesses with half of the vehicles being deployed in large enterprises and the other half at authorities and public enterprises as well as SME...
Electric Vehicle has been an international trend so various industries try to evaluate EV cost and commercial viability to get into this market. This study lists each cost parameter that may affect companies' acceptability of market transference from traditional fuel vehicle to Electric Vehicle (EV). Three types of cost parameters are included and they transferable costs, fixed cost, and variable...
Market development of electric vehicles in the coming years is a highly relevant issue for many stakeholders, e.g. automobile- and energy-industry, investors as well as policy makers and the public. The market forecasts, however, differ strongly and underlying assumptions are often hard to find. Furthermore, for stakeholders from such diverse fields it can be difficult to convey their own assumptions...
The vehicle-to-grid (V2G) framework proposes integration of battery-powered electric drive vehicles into the grid, enabling them to be recharged as necessary and to act as suppliers in the ancillary service electricity markets. This is expected to create incentives for the production and adoption of electric vehicles in the automotive industry. V2G frameworks require that the utility company or a...
The telecommunications industry has the greatest coverage among all utilities. Remote areas of the country that have no roads, grid-electricity, land line telephones or gas, still receive network coverage from one or more telecom companies. However, the Base Transceiver Systems (BTS) that these companies used in off-grid areas are dependent on on-site diesel generators, and the frequent maintenance...
An analysis is presented to show the technical and economic benefit of DC microgrid in comparison to the usual AC microgrid considering the socio economic condition of rural Bangladesh. Results show that the cost of energy can be significantly lower in the case of a DC grid.
The nature of transport and energy use is radically changing along with the upward trend of electric vehicles. The rapid technological development of electrical vehicles opens new opportunities from the electricity distribution point of view. Efficiency can be improved by implementing energy storages to the grid and cutting the load peaks by feeding power on peak hours from the energy storages to...
Demand side management will be a key component of future smart grid that can help reduce peak load and adapt elastic demand to fluctuating generations. In this paper, we consider households that operate different appliances including PHEVs and batteries and propose a demand response approach based on utility maximization. Each appliance provides a certain benefit depending on the pattern or volume...
Since the hourly spot market price is available one day ahead in Denmark, the electricity price could be transferred to the consumers and they may make some optimal charge and discharge schedules for their electric vehicles in order to minimize their energy costs. This paper presents an optimal operation strategy for a Plug-In Electric Vehicle (PEV) in relation to the hourly electricity price in order...
We consider a queuing model with applications to electric vehicle (EV) charging systems in smart grids. We adopt a scheme where Electric Service Company (ESCo) broadcasts one bit signal to consumers indicating on-peak periods for the grid. EVs randomly suspend/resume charging based on the signal. To model the dynamics of the population of EVs we analyze an M/M/∞ queue with random interruptions, and...
Plug-in Electric Vehicles (PEVs) have received much interest in recent years, as concerns about environmental quality, energy security and economic development have risen. Diverse strategies are adopted today by the industry to overcome the new challenges in this emerging market ranging from battery ownership, to charging, to demand response and to billing. However, strategy selection is not well...
Pioneering efforts in showing how electricity energy storage can be a valuable asset in a Smart Grid Distribution System have been in process for the last few years. Several demonstration projects were completed to show how substation loading could be controlled and managed to delay upgrades. The next step was to show how the load deferral benefit could be combined with distribution circuit automation...
This paper will discuss the purpose and value of energy storage as a transitional technology towards SmartGrids, as well as its utilization within the future network operational arrangements. The paper will investigate assessment techniques of energy storage at a local, system and global level, with a focus on the ways that energy storage may be valued. The paper will analyse existing techniques that...
