Constraint Handling in Transmission Network Expansion Planning

2010
Transmission network expansion planning (TNEP) is a very important and complex problem in power system. Recently, the use of metaheuristic techniques to solve TNEP is gaining more importance due to their effectiveness in handling the inequality constraints and discrete values over the conventional gradient based methods.

Transmission network expansion planning software-tools

2015 IEEE 10th Jubilee International Symposium on Applied Computational Intelligence and Informatics, 2015
The authors are proposing a software-tool for transmission network expansion planning (TNEP). The developed software-tool is able to be used in case of complex, large scale power systems. It uses a.c. complete power flow mathematical model. Power flow computing is performed using conventional methods.

Deterministic Approach for Generation and Transmission Expansion Planning

2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA), 2018
In this paper, the Generation and Transmission Expansion Planning (G&TEP) problem, considering two case studies, is analyzed. In the first case, the GEP and TEP problems are considered separately, while in the second GEP and TEP problems are solved together, thus G&TEP problem appears.

Bilevel Conic Transmission Expansion Planning

IEEE Transactions on Power Systems, 2018
In this study, a bilevel transmission expansion planning model using conic ac power flow formulation is presented. Both computational and simulation results of this model on three test systems are presented, which show that the resulting expansion plans, compared to those derived from a conventional linear power flow based bilevel model, are more ...

Complexity of transmission network expansion planning

Energy Systems, 2013
Transmission network expansion planning in its original formulation is NP-hard due to the subproblem Steiner trees, the minimum cost connection of an initially unconnected network with mandatory and optional nodes. By using electrical network theory we show why NP-hardness still holds when this subproblem of network design from scratch is omitted by ...

Transmission Expansion Planning in Electricity Markets

IEEE Transactions on Power Systems, 2008
This paper presents a mixed-integer linear programming (LP) formulation for the long-term transmission expansion planning problem in a competitive pool-based electricity market. To achieve optimal expansion planning while modeling market functioning, we define a number of scenarios based on the future demand in the system and we simulate the ...

Reliability Optimization for Transmission Expansion Planning

IEEE Power Engineering Review, 1982
A new quantitative method of incorporating system reliability constraints in transmission expansion planning is discussed. The objective of the new algorithm is to achieve a prescribed system reliability index, the system expected demand not served (EDNS) by suitably changing network element capacities.
