Avainsanat: | PLEXOS for power systems Brazilian power system eletricity market ancillary systems power system modelling |
Tiivistelmä (eng): | Power systems influence nowadays society in such a number of ways that one cannot ignore its importance. This translates to economical, structural and humanitarian factors that are a pillar to modern society. Understanding and developing these systems are pivotal for a development of any country. Brazil has been surging as a country in development on the past years, with reflections on its power system. Historically analysing and comprehending the current paradigm of the system and its structure is the first step one has to make. With billions of euros at stake within the electricity market, modelling and simulating are necessary steps when investing large sums of money. PLEXOS for Power Systems is software that can provide the support for this kind of analysis, which was used in the development of this work. After understanding how PLEXOS plays with complex databases revolving around the system, some simplifications were made due to the lack of data. Hydroelectric generation and load demand were estimated, types of generators were grouped, and interconnections were simplified. Introduction of wind generation and load intermittency creates less stable systems, resulting in the need of ancillary systems. The Brazilian system has its own rules regarding primary, secondary and tertiary reserves. A high dependency on hydroelectric sources is easily observed, the quick response times of the expensive fuel generators are critical, while gas powered utilities provide a steady, yet controllable and cheap, power source. The complexity of the system and lack of data translates into some errors in the simulation which are promptly discussed. |
