Combined cooling, heat, and power (CCHP) units can be integrated with conventional separate cooling, heat, and power production units to meet demands. The goal of this study is to develop and examine a hybrid GA-heuristic optimization algorithm for solving the unit commitment problem for integrated CCHP-thermal-heat only system with considerations for electricity boiler. When environmental emis...

A microbial fuel cell (MFC) is a device that converts chemical energy into electricity through the catalytic activities of microorganisms. In the present contribution, we demonstrated the comparative electricity production capacity of Saccharomyces cerevisae and Clostridium acetobutylicum in two chambered MFC using Artificial Waste water. Temperature, pH, substrate concentration and addition of...

Objectives • Develop the concept of a solid oxide fuel-fed electrolysis cell (SOFEC) for hydrogen production. • Identify and develop SOFEC cathode materials that are electrocatalytically and chemically stable in both reducing and oxidizing atmospheres. • Develop a novel concept of a composite/hybrid planar SOFEC-solid oxide fuel cell (SOFC) stack to co-generate hydrogen and electricity. • Demon...

Production factories in which stable voltage is critical, e.g., electro-plating factory, require constantly stable voltage to minimize loss by adjusting incoming voltage in real time, even if low-quality electricity is supplied from outside. To solve such problem often being raised from the factories located in the area with unstable electricity supply, we designed N-M switching control system ...

This paper deals with the development of offering strategies for a wind power producer considering a stochastic model. Several scenarios are analyzed and two kinds of uncertainty are simultaneously handled: wind power and electricity market prices. The proposed approach allows evaluating production and offering strategies to be submitted to the electricity market with the goal of maximizing pro...

While the main thrust of the Discussion Meeting Issue on 'Material efficiency: providing material services with less material production' was to explore ways in which society's net demand for materials could be reduced, this review examines the possibility of converting industrial energy demand to electricity, and switching to clean electricity sources. This review quantifies the scale of infra...

Due to exposure to uncertainty created by the deregulation of electricity industries worldwide and the need to respond to climate change via investment in more sustainable technologies, the challenges and opportunities facing power companies have increased over the past decade. Consequently, the electric power sector requires decision support that is more responsive to market conditions, while ...

This paper analyzes the effects of the green transformation on the German electricity sector with respect to the energy-political triangle. It focuses on how the development of renewable energies will affect security of electricity supply. In a cost-benefit analysis, the value of supply security is compared with its costs of provision. More specifically, the benefits of maintaining the present ...

The introduction of competition in the electricity sector around the globe is aimed at improving efficiency in production, transmission and distribution of electrical energy. Privatization and deregulation in this sector are also intended to attract players and investments in the markets as well as to ensure competitive electricity price. This paper presents the use of an agent-based simulation...

We use survey data for 139,517 individuals in 26 European Countries, 2002-2011, to estimate the relationship between subjective well-being (SWB) and production shares of various types of electricity generation. The estimated relationships are taken to represent preference relationships over attributes of electricity supply systems (costs, safety, environmental friendliness etc.). Controlling fo...
