The identification of energy consumption patterns contributes for the tailoring of energy efficiency solutions. This paper contributes to this issue by addressing the characterization of electricity consumption data with 15 min sampling of twenty two households, in Lisbon. The consumers have been segmented according to: social class, contracted power, number of rooms, family size and type of ta...

We present a variant of the alternating direction method of multipliers (ADMM) that can be implemented in a hierarchical distributed fashion for large-scale systems where the coupling between subsystems occurs in a structured way in the cost function. We show that this ADMM algorithm can be embedded in a model predictive control (MPC) implementation and subsequently apply this to three battery ...

The objective of the study is to analyse the conditions for connection of residential buildings in heat sparse areas to district heating systems in order to increase electricity production in municipal combined heat and power plants. The European electricity market has been assumed to be fully deregulated. The relation between connection of heat sparse areas, increased electricity and heat prod...

This system can fully prevent from human and financial losses that may cause by a variety of toxic and flammable gases. Its application of this system is in residential, commercial office, factories and etc. The mechanism of system is by radio waves. This system for preventing probable risks simultaneously cuts the electricity and gases of selected environments, the horn of alarm risk brought t...

Residential and commercial buildings accounted for about 68% of the total U.S. electricity consumption in 2002. Improving the energy efficiency of buildings can save energy, reduce cost, and protect the global environment. In this research, artificial neural network is employed to model and predict the facility power usage of campus buildings. The prediction is based on the building and the wea...

The price of electricity supplied from home rooftop photo voltaic (PV) solar cells has fallen below the retail price of grid electricity in some areas. A number of residential households have an economic incentive to install rooftop PV systems and reduce their purchases of electricity from the grid. A significant portion of the costs incurred by utility companies are fixed costs which must be r...

Current forecasts suggest that the vast majority of growth in energy demand will come from the developing world, and that China will play a major part in that growth. This paper presents evidence suggesting that the shape of the income distribution, which is typically omitted from forecasting models, plays a major role in driving household acquisition of energy-using durable goods in rural Chin...

Electricity demand response refers to consumer actions that change the utility load profile in a way that reduces costs or improves grid security. The focus of demand response has mainly been on the commercial and big industrial sectors because of the large demand reduction that they can offer to the utility grid operators. Utilities are showing increasing interest in residential demand respons...

On March 1, 2000, Maine will offer electric power through open competition, a restructuring that poses both advantages and disadvantages to residential and small retail consumers in Maine. While electric restructuring in Maine has been thoughtfully developed, the basic question of whether electricity rates will be lower for the average consumer will remain uncertain for some time. This uncertai...
