Two classes of problems are considered within the framework of a general approach to solve optimisation problems with fuzzy coefficients, referred to as and models in the literature. This paper is concerned with the latter and proposes an approach wh

A method of solving the preventive security-constrained reactive power VAr dispatch problem is presented. A decomposition-coordination scheme is conceived in order to take advantage of the special structure of the problem. Instead of tearing the netw

The main concern about market power in an electricity market is the concentration of ownership that would permit the exercise of market manipulation. The widespread potential for transmission congestion constraint is a crucial factor to improve the p

This paper integrates artificial intelligence techniques with sensitivity analysis for the formulation and resolution of the optimal reactive power flow (ORPF) problem. The objectives and constraints are transformed into fuzzy sets and the problem is

Two lines of improving the validity and efficiency in solving problems of network reconfiguration in distribution systems are considered. One line is associated with taking into account a power system reaction while minimizing power or energy losses.
