Use of the alternating current model for Integrated Multi-Capa Planning of the Expansion of Transmission/Subtransmission Lines and Reactive Power Sources in Electric Energy Systems

The planning of the expansion of the transmission system/Electrical Subtransmission (PET) consists in determining which additions, where and when they have to be carried out to meet the objectives of the electrical system. In Ecuador, the transmission system is managed by the public company Celec Ep - Transelectric, while electrical subtransmission systems are the responsibility of some of the distributing companies such as Centersur. To obtain sustainable expansion plans of those systems, in large part, advanced optimization tools (which Ecuador does not yet have) are needed that help planners make optimal decisions regarding the investments that are needed to make in the expansion of the infrastructure. In the current market there are almost no commercial solutions to perform this task, and those that exist incorporate very little updated models and methodologies that no longer apply to the current and future situation of electrical systems, both nationally and internationally. In this project, it is proposed to develop a tool to solve the multi-staple planning problem of the integrated expansion of transmission/subtransmission lines and reactive power sources, considering the exact model of the electricity grid. The results will be obtained using the Garver test system, the Subtransmission System of the Centersur and the Ecuadorian Transmission System. This project will help improve Ecuador's ability to carry out the PET in accordance with the National Development Plan of Ecuador (PND).
