This paper presents a tariff's computation approach for electrical energy distribution systems. The described methodology was developed from the traditional tariff-calculation method used in Brazil. The approach combines the concepts of time-of-use tariffs and Ramsey prices. The resulting tariffs for both consumer and generation units, besides having an hourly signal associated with long-term marginal...
The use of renewable energy sources is escalating every year. Thus, there is an increase of smaller generating units connected directly to distribution networks close to demand consumption, designing micro-grids. These sources must provide the power quality required to ensure the stability and reliability of the power system. Several studies are demanded to ensure system operation in a secure manner...
This work presents the demand market share as a crucial element on the tariff establishment process. The proposed approach permits that the established tariffs are properly technical (based on the marginal cost of power supply) and efficient on the network optimization point of view. For the analysis, an econometric model of the load is considered. The results are obtained using the Energetic Company...
This paper presents a methodology to deal with voltage stability and system loss reduction in distribution systems. In order to come up with sensitivities indicators, the Newton method must be employed, and a rotation in the data is executed. Then, the buses most indicated to experiment shunt compensation for active and reactive loss reduction and voltage stability prevention are identified. The tests...
