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...
This paper reports on customer interruption cost (CIC) measurement in the commercial and industrial sectors. It accommodates the time-dependence of interruptions. It proposes a method of predicting the probability of such interruptions and of their cost. A method of scaling CIC is proposed for different sizes of customer. The result of the whole approach is the probabilistic financial impact assessment...
Basic: The Indexes System for electricity market is the basement for quantitative analysis of electricity market. It is very important to induce math tools to deal with these indexes. This paper will research on the quantitative analysis methods for Electricity Market, which is of significant meaning for the electricity market. It is a necessary mathematical tool helping the market supervisors to...
This paper studies the maintenance decisions of generating companies (GENCOs) which are fully engaged in oligopolistic electricity market. Maintenance decisions in an oligopolistic electricity market have a strategic function, because GENCOs usually have impacts on market prices through capacity outages. The main contribution of this paper is modeling a game theoretic framework to analyze strategic...
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...
The integration of large shares of wind generation in power systems requires the development of new algorithms and forecasting tools for making decisions in the operational domain taking into account wind generation forecast uncertainties. One of these decisions regards operating reserve requirements to meet load and wind variations. The aim of this paper is therefore to address this issue from a...
Transmission network was recognized as natural monopoly and almost everywhere subject to some kind of regulation in a restructured electricity market. The role of the transmission system is to provide an indiscriminate access for all market players along with an acceptable level of reliability and security. Regulating authorities have to decide about the augmentation investment. As an on going research...
Due to the large amount of electrical equipment and the costs of an individual diagnosis in distribution networks, a life assessment of the representative electrical components is necessary. For a thorough electro-thermo-mechanical life model of the electrical components, the individual aging phenomena of the representative electrical components as well as the general aging mechanisms of insulating...
In the present paper, the authors propose a new method to determine an optimal transmission expansion plan in the deregulated power system. In the proposed scheme, social welfare and reliability are taken into account. Social welfare is computed from the summation of welfare of all market participants. On the other hand, reliability is determined from the cost of the loss of load or outage cost of...
