Flujo óptimo de potencia : revisión bibliográfica de las propuestas de modelación y solución del flujo óptimo de potencia

Abstract

An Electrical Power System (EPS) requires an efficient, reliable, and secure economical operation; nowadays, there are several tools available to make that possible. Optimal Power Flow study (OPF) is laid on this category because it is used for making planning and analysis of EPS. In general terms, OPF has the purpose of determining the control variables settings minimizing or maximizing an objective function. This function is previously defined while the electrical network restrictions or bounds are respected. OPF problem was formulated for the first time at the beginning of the seventh decade, and since then, it has become more important due to its applications and its technique and formulation development. Those have achieved feasible solutions for this complex issue. In this way, there is a large variety of proposals for OPF formulations, solve methods, case studies, and computational tools. Hence, it is advisable to discriminate and prioritize the existing information related to the subject. This project was developed by using a previous scanning about the OPF background extracted from various research, scientific projects, papers, and related books. The collected information is integrated and organized considering some indexes such us variables, restrictions, purpose, solution methods and computational tools. A database from SNI was created in Excel to solve OPF research by using free software tools like PandaPower and Matpower. The database was validated by comparing the results obtained from free software tools with those achieved using DIgSILENT PowerFactory. After that, optimal power flow studies were developed using this database by the aid of PandaPower and MatPower considering different conditions.
