Cálculo da capacidade remanescente de um sistema elétrico para escoamento de geração de energia

Abstract

This paper addresses the calculation of the remaining capacity of an electrical system for power generation flow, which consists of the maximum value of active power injection that the system can transmit without the occurrence of power flow violations. or tension. This topic is very relevant, especially in Brazil, where there is great energy potential and projects to expand and diversify the energy matrix. This subject is extremely important in the commercial scope of electric energy, since it is a study that precedes some energy auctions under the responsibility of the Ministry of Mines and Energy. Throughout the paper, the fundamentals to understand the problem and a computational method for its resolution are presented. The software used to perform the calculation, ANAREDE®, will also be presented, with emphasis on its automatic transmission margin calculation tool. Finally, the results from the software calculations are presented, exposed through tables containing the values of the transmission margins and their limiting factors.
