This paper provides an approach to the problem of power distribution network renewal planning where the challenge to the decision maker is to determine the most cost- effective multi-year development plan in terms of what feeders in the network to refurbish, by which renewal alternative and at what time in the planning horizon. The problem is subjected to several constraints of service requirements...
This paper focuses on the application of risk-based models to cogeneration system planning in the presence of uncertainties. Starting from the electrical and thermal load patterns, and the electricity and gas prices for a reference year, the uncertain variables for the successive years of analysis (demand and energy prices) are represented by using average values and covariance matrices, taking into...
The following topics are dealt with: uncertainty forecasting; wind generation; decision making; generation planning; load forecasting; power generation scheduling; ageing model; power system reliability; distributed generation; failure probability; transformer reliability; electricity markets; power equipment optimal allocation; power system protection; power system planning; and HVDC.
It is recognized today that short-term (up to 2-3 days ahead) probabilistic forecasts of wind power provide forecast users with a paramount information on the uncertainty of expected wind generation. When considering different areas covering a region, they are produced independently, and thus neglect the interdependence structure of prediction errors, induced by movement of meteorological fronts,...
The application of the telecontrolled switching elements in MV distribution networks is an effective tool for influencing the electricity supply continuity perceived by individual customers considerably. In this way, it is also a tool for reducing the possible costs resulting from breaching the customer's standards of electricity supply continuity. A method generally utilizable when making decisions...
This paper illustrates the challenges associated with risk assessment for reinvestments decisions. A holistic framework for risk assessment in electricity distribution systems will be described first and then used to structure the analysis and decision making in a case study concerning cable reinvestment. These decisions are generally multi criteria decisions, including risks related to e.g.; economy,...
For many years, the electric power industry treated electricity as a unique commodity sold to costumers. Nowadays, the new electricity industry has identified several key ancillary services. Under this new scenario, the producer's primary goal is the selection of services in which to participate via assessing the potential profits as part of the decision-making. Purchasing additional information can...
Considerable research has been devoted on the development of decision-making models suitable for tackling decision problems integrating some amount of uncertainty. However, such approaches are either problem-specific, either too general to suit certain problems. In this paper we propose an approach for performing decision-making under uncertainty suitable for problems in which decisions must be made...
