Evolutions in the power system challenge the manner in which power system reliability is managed. In particular, currently used reliability criteria, typically the deterministic N-1 criterion, are increasingly inadequate. Moving to an alternative approach is difficult as quantifying benefits is hard in a multifaceted environment and system operators are reluctant to move away from the easy and transparent...
Evaluating the performance of various power system reliability criteria and their management is important in order to obtain a cost effective reliability level of the power system. However, the performance of reliability criteria depends on several parameters, of which one is value of lost load (VoLL). Value of lost load is typically difficult and complex to model, which hampers making a general conclusion...
Solid power system planning is fundamental to the safety, reliability and economy of power system operation. In the deregulated power grid environments, power grid planners not only have to handle massive geographic data, power equipment parameter data and grid operational data, but also have to solve very complex decision-making problems when they are committing power grid planning. Thus, it is necessary...
The Ant Colony Algorithm is introduced to network planning for searching a group of network constructions within the constrains of distribution system. Several evaluating indexes such as power losses, mass loading ratio, H-1 certification are mentioned, and the weights of every factor are obtained by Analytical Hierarchy Process. Mathematical function is used to analyze every network, and the optimal...
The present study, firstly, puts forth a comprehensive and reasonable reliability assessing theory system directing at fuzzy layers and the incomprehensive factors of current distribution network. Next, the four major characteristics influencing reliability of the distribution system have been defined and research has been conducted on grade one and grade two as well as basic index involving those...
This paper summarizes the current practices of transmission expansion and pricing in Colombia. Transmission expansion in Colombia is formulated by a central governmental agency that is commissioned to establish the required transmission enhancements. The commission consolidates all the needs based on economic growth and the current regulation into a single plan. We review how the single plan is elaborated...
We propose a general structure of Benders decomposition for power system decision making. In this framework, three elements of decision-making problems in power systems are mapped into the three types of subproblems of the Benders decomposition approach. An information communication strategy is introduced. We also explain how the approach facilitates the unbundling of computational services.
