Joint planning of the optimal expansion of generation and transmission electrical systems

This research project focuses on proposing a formulation and solution method for the problem of integrated planning of the expansion of generation and transmission (PEGT) in electrical systems based on the AC model. The PEGT is crucial to determine the optimal capacity of the generation units, the adequate combination of energy resources, its location and the moment of entry into operation. It also addresses the future infrastructure of the transmission system to ensure efficient and reliable delivery of energy. Generally, the planning of the expansion of the generation (PEG) and the planning of the expansion of the transmission (PET) are carried out sequentially, resulting in expensive proposals, since they do not consider the interaction of these two problems simultaneously. In addition, the scarce research on the PEGT model the transmission network through mathematical relations of the continuous current load flow, which does not represent the current and future situation of electrical systems. This project proposes to solve the PEGT representing the transmission network through the alternating current model. To achieve this, metheuristic optimization techniques will be used, combined with parallel computing and local improvements to increase the efficiency of algorithms. The methodology will be implemented in the Julia programming language and the results will be obtained using test systems accessible to the scientific community. This project will help improve the planning capacity of Ecuador in accordance with the National Development Plan of Ecuador.
