Technical, Regulatory, and Social Issues to Make a City Electrically Smart

Abstract

To make cities smarter has become a worldwide purpose as predicted in the United Nations Sustainable Development Goals. In modern power systems, reliability and self-sustainability are crucial requirements. This paper assesses the ability of a real microgrid to operate in islanded mode when a failure of any nature takes place. The circuit analyzed belongs to the satellite city of Taguatinga, located in the suburban area of Brasilia, the Brazilian Capital City. The city electrical data make Taguatinga similar to large cities in the Brazilian context. This work presents the electricity data, as voltage levels, consumption and, local distributed generations. The purpose is to propose solutions for technical, regulatory, and social issues needed to make the city, at least, four days electrically self-sustainable. It was concluded that a tremendous global effort, including government, regulators, and society, will be necessary to make any Brazilian city a smart city, electrically leastwise.
