In a power grid, supply and demand must always be balanced. The traditional approach is to ensure enough supply margins and redundancy to meet demand peaks. This approach is not always feasible in a physically or fiscally constrained environment, or when a system malfunction ("contingency" in power systems parlance) triggers a power deficit. A demand-response mechanism integrates demand...
Demand side management (DSM) has considerable potential to reduce power system generation, transmission and distribution costs. However, the integration of DSM into existing restructured electricity markets is not straightforward. Here, major areas of research into DSM will be reviewed, and the elements of most interest identified, particularly in the context of the Australian National Electricity...
The response of demands to disturbed supply conditions is considered in this paper as an input parameter for the decision of the restoration of a smart distribution system. A new module to investigate the response of demand side to the disturbances in the decision of restoration plan is developed. With the installation of advanced metering devices at homes and businesses the end-use customers are...
Electricity market players operating in a liberalized environment requires access to an adequate decision support tool, allowing them to consider all the business opportunities and take strategic decisions. Ancillary services represent a good negotiation opportunity that must be considered by market players. For this, decision support tools must include ancillary market simulation. This paper proposes...

With respect to characteristics of block trading rules, integrating various implementation mechanisms of demand side bidding (DSB), block bidding mechanism is extended to demand side and theory framework of block bidding mechanism incorporating demand side participation is proposed. Based on electricity pool pattern and with block bidding rules, electricity sellers and buyers can perform electricity...
Although the financial crisis shrinks oil price, human as an entire race still face the future of a hot, flat and crowded world [1]. Therefore, a critical transformation from our traditional energy consumption manner of fossil fuel combustion must be made. After years of endeavor in research and experiment, a number of Renewable Energy Sources (RES) has already become technically available as alternatives...
Power systems are planned and operated according to the optimization of the available resources. Traditionally these tasks were mostly undertaken in a centralized way which is no longer adequate in a competitive environment. Demand response can play a very relevant role in this context but adequate tools to negotiate this kind of resources are required. This paper presents an approach to deal with...
Presently power system operation produces huge volumes of data that is still treated in a very limited way. Knowledge discovery and machine learning can make use of these data resulting in relevant knowledge with very positive impact. In the context of competitive electricity markets these data is of even higher value making clear the trend to make data mining techniques application in power systems...
