In this paper, we consider the coordinated charging control of electrical vehicle (EV) in the charging stations. The goals are to minimize the total charging cost of all the vehicles at the charging station, respecting subscription type to electricity for charging station. The algorithm is based on a given future electricity prices and uses linear programming. This cost reduction of charging being...
This paper examines the potential to create an energy-independent smart network for an island community utilizing ocean and wind energy. The analysis involves the simulation of an extensive electrification of the heat and transport sectors on the island and the use of renewable energy to maximize the fuel and emission savings. This study involves a full renewable resource assessment for both wind...
Since renewable sources, such as wind and solar power plants, suffer from their stochastic nature, their behavior on market is very delicate. In order to diversify the risk, a concept of virtual power plant is developed. The virtual power plant is consisted of several renewable energy sources and at least one conventional power plant. The production of renewable energy sources cannot be perfectly...
Plug-in electric vehicles (PEVs) represent both a new challenge for and a huge potential resource to the smart-grid. The secret to effective integration of renewable energy generation into the smart-grid is integration of enough storage to deal with the intermittency of the generation. However, there are several barriers to integrating enough storage to effectively harness renewable energy in the...
We consider an Energy Services Company (ESCo) acting as a mediator between the wholesale market and the PHEV owners providing them with energy for battery charging using the distribution network as the delivery infrastructure. Furthermore, the ESCo exploits the flexibility in the charging process by offering reserves in the market. To achieve this objective, the ESCo faces the decision problem of...
Thailand currently relies largely on natural gas, coal & lignite, fuel oil, and less portion in renewable energy for electricity production. Due to the cheap fuel costs, fossil fuels dominate in energy supply. However, utilization of more fossil fuels results in increasing CO2 emissions. The introduction of carbon dioxide capture and storage (CCS) for the future thermal power plant in Thailand...
Renewable generating technologies offer an effective means for climate change mitigation and guaranteeing energy security. As we all known that, the widespread perception that these renewable generating technologies have more risk than conventional alternatives. So, it is an investment-decision problem. Investors commonly evaluate such problems using portfolio theory to manage risk and maximize portfolio...
The purpose of this paper is to economically evaluate the use of a fuel cell along with a photovoltaic array to provide electricity to residential houses. The use of a fuel cell is compared to the use of a battery as a way of storage. Different scenarios are presented regarding the use of the fuel cell with the PV system and the grid. Each scenario was based on an arrangement of the energy sources,...
