A local search strategy for static transmission expansion planning (TEP) is presented in this paper. Removing one circuit in current transmission plan may make some components overloaded, some buses isolated or the remained system intact. Based on the three situations, three sets known as local bus, local circuit and effective local circuit are defined, and accordingly the neighborhood of current...
More and more transmission planning has to cope with a multilateral context due to increased electricity exchanges between zones. Whereas investments are decided upon and approved at the zonal level, policy goals can be formulated at a higher supranational level. The zonal level, however, can have its own objectives or way to reach the policy goals. This is possibly conflicting with the supranational...
The restructuring and deregulation has exposed the transmission planner to new objectives and uncertainties. As a result, new criteria and approaches are needed for transmission expansion planning (TEP) in deregulated electricity markets. This paper proposes a new market-based approach for TEP. An enhanced differential evolution (EDE) model is proposed for the solution of this new market-based TEP...
This paper presents the application of a memtic meta-heuristic optimization technique known as Shuffled Frog Leaping Algorithm (SFLA) to the problem of transmission network expansion planning. The main objective of the proposed problem is to minimize total cost by finding the place, number and type of new transmission lines required to ensure that the power system meets the forecasted demand in the...
Reliability problems encountered within planning studies may typically be corrected either by building new transmission or by installing an SPS. SPS are almost always much less expensive ways to correct reliability problems, since they generally require only relays, communication equipment, computing and associated actuation logic, and tripping devices. However, SPS increase operational complexity...
The main objective of transmission expansion planning in deregulated power systems is to provide a non-discriminatory competitive environment for all stakeholders, while maintaining power system reliability. In this paper, a static transmission expansion methodology is proposed using a multi-objective optimization framework that is able to handle different incommensurable objectives with conflicting...
This paper proposes a methodology to solve the multi-stage transmission expansion planning (TEP) problem based on metaheuristic optimization techniques, as load and generation evolve. A discussion on how to consider security criteria using the well-known deterministic “N-1” approach and the probabilistic reliability-based method is presented through a case study system.
