Communication Technologies integration into the Electrical System of the city of Praia

The electric sector in small island states, such as Cape Verde, have many related weaknesses, such as: high percentage of commercial losses-mainly theft, difficulty in integrating renewable energy and lack of quality in energy supply, which has reflected in a high cost of electricity. In this sense, Smart Grid technologies have been one of the main bets to guarantee the sustainability of the ES in these regions, to improve its reliability, to maximize its energy efficiency and to increase its robustness. Thus, the integration of technologies such as: SCADA / EMS / DMS, Smart Meters and DER, requires a two-way communication system that interconnects the whole system, allowing to monitor and control the entire electrical network, giving it the ability to identify and correct almost instantly, the constraints caused by demand. This paper presents an architecture proposal for the communication system that could be coupled with the ES of Praia, as a way to guarantee the integration and communication of SG technologies, as well as to enable new applications and services that would assist in the management of all sector. The proposed communication system architecture results from the application of international precepts and norms as well as the results obtained through simulation software, taking into account the existing endogenous technologies and the geographic and socioeconomic conditions of the city.
