In this paper, a new approach for preventive maintenance of generating units in a competitive market environment is proposed. The objective of the generator maintenance scheduling (GMS) problem is to find the precise time interval for maintenance of power generating units with an objective criterion of maximizing the profit of individual generation companies (GenCo’s) present in an electricity ...

The recent handling over of the assets of Power Holding Company of Nigeria (PHCN) successor companies to the core investors was a major landmark in the reform of the electric power sector in Nigeria. However, the emergence of the different autonomous utilities for running the deregulated electricity market has great consequent for the day-to-day planning and operation of the power grid. There i...

Although many countries prefer deregulated power markets as a means of containing costs, monopoly may still exist. In this study, an agent-based bidding simulation framework is proposed to detect whether there will be in the market. A security-constrained unit commitment (SCUC) conducted clear Using characteristics that agent can fully explore certain environment and Q-learning algorithm, each ...

Since the nineties decade, many electric utilities world-wide have been restructuring their systems from vertically integrated functioning to deregulated open-market ones. In the erstwhile vertically integrated utilities, the system operator sought to maximize the social welfare with distributional equity (meeting the load at all time) as the main criteria, for the system as a whole. The operat...

This paper presents the AGC controllers to regulate the system frequency and to regulate the power generation of various GENCOs at scheduled levels in a deregulated power system by optimizing the parameters of controller using Evolutionary Real coded genetic algorithm (RCGA). The performance of the controller is investigated on a two-area interconnected power system consisting of Hydro-Thermal ...
