In this paper, an enhanced congestion control scheme for market related applications is presented. Based on the concept of Marginal Value Expansion, violated transmission constraints can be handled more effectively in the optimization process. Compared to the traditional congestion control method, available resources in system can be utilized more sufficiently. The effectiveness of the new scheme...
In this paper we develop a model of combined heat and power (CHP) dispatch for the system consisting of both thermal generators and wind turbines. In this model, the probability of stochastic wind power is included in the constraint set. This approach avoids the probabilistic infeasibility caused by using the average of random variables. The effects of wind speed on the generated power are investigated...
This paper contributes to the discussion about the future integration of Smart Grids in the existing energy supply system on a mostly economical and regulatory point of view. One of the main issues in this case is the increasing costs due to grid enhancements under regulated grid tariffs. On the one side a concept based on an integrative customer oriented approach is described and the new roles of...
We present an incentive policy design model consisting of lower level and upper level optimization to promote renewable energy. The lower level optimization is a generation expansion planning (GEP) problem, in which the planner aims to expand an energy system's generation capacity to serve projected load with minimum cost. In the upper level optimization, to achieve the goal of specific percentage...
Electricity market players operating in a liberalized environment requires access to an adequate decision support tool, allowing them to consider all the business opportunities and take strategic decisions. Ancillary services represent a good negotiation opportunity that must be considered by market players. For this, decision support tools must include ancillary market simulation. This paper proposes...
Supplying a reliable, efficient, economic electrical service to all customers is the basic responsibility of utilities. However, increasing penetration of new customers in distribution grids as dispersed generation (DG), electric heating systems and electric vehicles (EV), makes conventional operation of energy supply systems difficult while meeting the aforementioned responsibility. Therefore, the...
The most significant energy consuming infrastructures and the greatest contributors to greenhouse gases in the US today are electric and freight/passenger transportation systems. Technological alternatives for producing, transporting, and converting energy for electric and transportation systems are numerous. Selecting from among them requires long-term assessment since these capital-intensive infrastructures...
