Transmission Expansion Planning in Restructured Power Systems Considering Investment Cost and n-1 Reliability

Transmission investment and expansion planning in a restructured electricity market

Transmission planning in a restructured electricity market becomes increasingly complicated. To bridge the gap between economic and engineering considerations, this survey paper suggests a framework to clarify the interactions among various economic and engineering issues by reviewing recent theoretical and practical progress in transmission investment and transmission planning methodology. Thu...

Transmission Expansion Planning Considering Network Adequacy and Investment Cost Limitation using Genetic Algorithm

In this research, STNEP is being studied considering network adequacy and limitation of investment cost by decimal codification genetic algorithm (DCGA). The goal is obtaining the maximum of network adequacy with lowest expansion cost for a specific investment. Finally, the proposed idea is applied to the Garvers 6-bus network. The results show that considering the network adequacy for solution...

A Probabilistic Approach to Transmission Expansion Planning in Deregulated Power Systems under Uncertainties

Restructuring of power system has faced this industry with numerous uncertainties. As a result, transmission expansion planning (TEP) like many other problems has become a very challenging problem in such systems. Due to these changes, various approaches have been proposed for TEP in the new environment. In this paper a new algorithm for TEP is presented. The method is based on probabilisti...

A Transmission Expansion Planning Model for Maximizing Merchant Investment

Transmission Reliability Cost Allocation Based on Contingency Filtering by Economic Indices in Large Power Systems

In this paper, the new approach for the transmission reliability cost allocation (TRCA) problem is proposed. In the conventional TRCA problem, for calculating the contribution of each user (generators & loads or contracts) in the reliability margin of each transmission line, the outage analysis is performed for all system contingencies. It is obvious that this analysis is very time-consuming fo...
