When there are differences in economic value of self-consumed and exported electricity, economic profitable PV installations are dependent of accurate predictions of selfconsumed electricity. In this study, minute based data of PV production and the electricity use were logged in a single family house in Sweden. It is shown that when self-consumed electricity is estimated, a low time resolution...

The possibility of generating electricity with microbial fuel cells has been recognized for some time, but practical applications have been slow to develop. The recent development of a microbial fuel cell that can harvest electricity from the organic matter stored in marine sediments has demonstrated the feasibility of producing useful amounts of electricity in remote environments. Further stud...

In a competitive electricity market environment, power producers and consumers need, on one hand, accurate load and/or electricity consumption forecasting tools. These tools will ensure an a-priori knowledge on the amount of energy needed for production. On the other hand, forecasting electricity prices, may play a very important role for producers and consumers when planning bidding strategies...

electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. electric motors account for between 43 and 46% of all global electricity consumption approximately. they give rise to about 6 040 mt of co2 emissions. end‐users approximately spend usd 565 billion per year on electricity [1]. in recent years, increase in e...

Fuel substitution in OECD-European electricity production is described by a putty-clay formulation. At the time of investment, fuel shares are determined according to a logit model. These fuel shares are maintained throughout the lifetime of the power plants. However, a significant share of capacity is assumed to be flexible. Short-term fuel switching is described by a logit model. An attempt h...

This paper proposes a smart grid solution for the electricity needs of North and East Sri Lanka (NE-SL); the solution proposed in this paper is a collection of smaller and greener electricity generators, geographically dispersed throughout the NE-SL region. At present, electricity is not available in most of the NE-SL due to the civil war. There is practically no electricity production and dist...

This research has determined the carbon footprint or the carbon dioxide equivalent (CO2 eq) of potable water production from a groundwater recycling scheme, consisting of the Beenyup wastewater treatment plant, the Beenyup groundwater replenishment trial plant and the Wanneroo groundwater treatment plant in Western Australia, using a life cycle assessment approach. It was found that the scheme ...

Future energy systems and thus the climate are affected by many factors, such as energy resources, energy demand, energy policy and the choice of energy technologies. Energy systems of the future are facing three main challenges; the steady growth of global energy demand, the energy resource depletion, as well as the increasing emissions of carbon dioxide (CO 2) and other greenhouse gases and t...

The task of optimal long-term planning of electricity production capacity considering uncertainty intervals of the base, peak and intermediate loads, and multistage nature of the planning process will be tackled. Theoretical min-max approach to the problem will be given. Model uses dynamic programming and takes into account also constraints on structure of generating capacity and security of su...
