To cut customers to integrate their onsite renewable deployments carbon footprints, electric utilities are incentivizing renewable with the electric grid. It allows customers to generate onsite energy integration through net metering and introducing time- of-use pricing plans to cut demand peaks, as peaks significantly electricity (e.g., using solar panels); generated energy is used contribute to both generation costs and carbon emissions. Net to satisfy customers demand, and any surplus generation is metering is one of the most popular means of integrating sold back to the grid. In its current form, net metering has distributed renewable generation in the grid. However, the two crippling limitations: 1) it doesnt adequately cut peaks, current net metering approach doesn’t effectively cut demand as energy harvest peaks and demand peaks are out of sync; peaks because renewable harvest peak and demand peaks are out of sync. Furthermore, as several states impose net metering for instance, solar power harvest peaks earlier in the day, but subscriber limits of less than 1% of the peak, net metering isn’t household peak demands typically occur around dinner times; even close to realizing the full potential of renewable integration 2) many states impose subscriber limit to less than 1% of the in the grid.

Traditionally, cooling demand is met by decentralised electrically driven appliances which affect energy, economy and environment as well. District Cooling Plant (DCP) is an innovative alternative means of providing comfort cooling. DCP is becoming an essential infrastructure in modern city development owning to many benefits compared to decentralized cooling technology. Demand Response Management (DRM) is largely applied for Demand Side management of electrical grid. Demand of electrical energy is closely connected with the demand of alternative form of energy such as heating, cooling and mechanical energy. Therefore, application of DR concept should be applied beyond the electrical grid; in particular, it could be applied to any interconnected district energy systems. District Cooling Plant is one of a potential candidate and Demand Response management solutions can be applied to DCP for sustainable operation.

However, the interactions between a higher number of electric vehicles and the impacts on power plant capacities have not been sufficiently investigated yet. Hence, this paper develops an approach to evaluate the energetic impacts on current power plant capacities that result from a higher market penetration of electric vehicles by 2030. The key aspect of the approach is the quantification of smart charging processes in energetic and economic perspectives. It was found that the implementation has significant energetic and thus economic benefits because of an improved integration of the additional electricity demand. The value of information systems which enable smart charging processes is shown by the calculated cost-saving potentials, resulting from a reduced expansion of the power plant system. Keywords Electric Mobility, Smart charging processes, Security of Energy Supply, Economic Appraisal INTRODUCTION Over the last decades, there has been continuous growth of the demand for individual mobility, seen particularly in increasing car sales. However, recent trends indicate a fundamental paradigm shift in the automotive industry. This trend has been initiated by a gradual substitution of electric vehicles1 (EVs) for vehicles with a combustion engine (Urbschat and Bernhart, 2009).

    MARIA ASLAM VEHICLE TO GRID CONCEPT AS PART OF POWER SYSTEM AND ELECTRICITY MARKET Masters of science thesis Examiner: Prof. Pertti Järventausta Examiner and topic approved by the Faculty Council of the Faculty of Computing and Electrical Engineering on 5th October 2016 i ABSTRACT MARIA ASLAM: Vehicle to grid concept as part of power system and electricity market Tampere University of Technology Master of Science Thesis, 55 pages January 2016 Master’s Degree Programme in Electrical Engineering Major: Smart Grids Examiner: Professor Pertti Järventausta Keywords: EV, RES, V2G, Intelligent charging The demand of electricity is increasing day by day with the increase in world’s population. Renewable energy sources (RES) are being integrated into the smart grid system. Renewable energy sources have fluctuating nature such as wind and solar power, and thus accurate forecasting of generation from these sources is nearly impossible. At the distribution end, load forecasting is also challenging as the load demand is not constant all the time. Hence to deal with the intermittent nature of RES and to fulfil the peak load demand, there is a need for a storage system that can be integrated with the smart grid environment. Electric vehicles (EVs) serve this purpose and replace the internal combustion engine vehicles in transportation. They are considered as mobile energy storage systems which do not only reduce the environmental pollution but also provide power to the grid in peak load time by storing energy in their batteries at off peak times when the demand is quite low. The aim of this thesis is to understand the concept of V2G.

  • New Jersey Peaker Power Plants Energy Storage Replacement Opportunities
    PSE Healthy Energy j May 2020 New Jersey Peaker Power Plants Energy Storage Replacement Opportunities Across New Jersey, 15 gas- and oil-fired peaker power plants and peaking units at larger plants help meet statewide peak electric demand. These facilities are primarily reliant on combus- tion turbines designed to ramp up quickly and meet peak demand. One-third of New Jersey peaker plants primarily burn oil, and two-thirds are over 40 years old; these facilities in particular have high rates of greenhouse gas and criteria pollutant emissions for every unit of electricity generated. Moreover, these plants are located disproportionately in low-income and minority communities, where vulnerable populations al- ready experience high levels of health and en- vironmental burdens. Many of the New Jer- sey peakers operate infrequently, suggesting they may be good targets for replacement with en- ergy storage.

  • I Assessing Vehicle Electricity Demand Impacts On
    Assessing Vehicle Electricity Demand Impacts on California Electricity Supply by RYAN WILLIAM McCARTHY B.S. (University of California, San Diego) 2002 M.S. (University of California, Davis) 2005 DISSERTATION Submitted in partial satisfaction of the requirements for the degree of DOCTOR OF PHILOSOPHY in Civil and Environmental Engineering in the OFFICE OF GRADUATE STUDIES of the UNIVERSITY OF CALIFORNIA DAVIS Approved: Joan M. Ogden Christopher Yang Daniel Sperling Committee in Charge 2009 i ABSTRACT Achieving policy targets for reducing greenhouse gas (GHG) emissions from transportation will likely require significant adoption of battery-electric, plug-in hybrid, or hydrogen fuel cell vehicles. These vehicles use electricity either directly as fuel, or indirectly for hydrogen production or storage. As they gain share, currently disparate electricity and transportation fuels supply systems will begin to “converge.” Several studies consider impacts of electric vehicle recharging on electricity supply or comparative GHG emissions among alternative vehicle platforms. But few consider interactions between growing populations of electric-drive vehicles and the evolution of electricity supply, especially within particular regional and policy contexts. This dissertation addresses this gap. It develops two modeling tools (EDGE-CA and LEDGE-CA) to illuminate tradeoffs and potential interactions between light-duty vehicles and electricity supply in California. Near-term findings suggest natural gas-fired power plants will supply “marginal” electricity for vehicle recharging and hydrogen production. Based on likely vehicle recharging profiles, GHG emissions rates from these plants are more than 40% higher than the average from all generation supplying electricity demand in California and 65% higher than the estimated marginal electricity emissions rate in California’s Low Carbon Fuel Standard.
