13. Melhoria das margens de estabilidade de tensão no problema do pre-despacho da operação atraves de corte mínimo de carga
The new philosophy of operating electric power systems exploring their maximum power transfer capability has placed the systems close to their stability limits. Therefore, it is important to assess the distance from the equilibrium point to the system voltage stability limit, and how to keep an adequate security margin from this limit. Considering the import

14. VOLTAGE STABILITY REINFORCEMENT ON ELETRIC POWER SYSTEMS / REFORÇO DAS CONDIÇÕES DE ESTABILIDADE DE TENSÃO NA OPERAÇÃO DO SISTEMA ELÉTRICO
As the electric power transmission networks became more interconnected, the thermal limits of lines and transformers restrict less the power transmission. Similarly, the use of static systems of reactive power compensation increases the power transmission capacity in systems whereas before they were limited by problems of angular stability. Actually, transmi

15. Obtenção do ponto de maximo carregamento em sistemas eletricos de potencia utilizando novas tecnicas de parametrização para o metodo de continuação
This work presents the features of new methods obtained with small modifications of the conventional Newton and fast decoupled methods. With the proposed modifications the problems caused by ill conditioning of the conventional methods for the determination of the maximum loading point and voltage stability margin ca1culation are avoided. New parameterizatio
