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...
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...
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...
