In this thesis a method is developed to determine the dispatch of generation units and the optimal load shedding in the operational planning of electrical power systems required to maintain security in a local area of a power system, minimizing the total cost of operation and rationing. The proposed methodology evaluates the security of the system to identify the local area of analysis and determine a short list of contingencies from a larger set of possible contingencies, which is considered to determine the generation dispatch required by security at various levels of the load duration curve of the local area. Likewise, it is assumed that in the local area exist generation with retirement plans and that they are candidates to maintain security in the local area, for which the objective is to identify the generation and its required dispatch, which could be establish an agreement called “Reliability Must-Run” (RMR) to remain available on the system. The optimal load shedding represented as fictitious generation in load bars, allows to cover the security of the local area where the RMR generation is not able to cover. The proposed methodology is based on an optimal power flow problem with security constraints (FPORS) formulated as an economical dispatch and solved using a metaheuristic with genetic algorithms (GA) to determine the dispatch of the generation required to maintain security in a local area. The AG chromosome includes as a variable the active power of the generation required for security, and the objective function is the total operating cost that includes the thermal cost and the penalties for violation of operating restrictions. The optimization of the decision or control variables and the objective function (thermal operation cost and penalties for violation of the operation restrictions) of the FPORS problem allows obtaining the dispatch of the generation units that meet with the operation restrictions in normal operating conditions and in the event of contingencies, that is, it maintains security in a local area, when verifying that the penalties are null.
