Are microgrids safe in Brazil?

In Brazil, although PRODIST establishes the islanded operation of part of the distribution system, Discos, for protection, safety and energy quality, have vetoed this practice. Although there are no specific rules for dealing with microgrids, the IEEE 1547 18 stands out.

Is there a microgrid business model in Brazil?

There is no discussion about microgrid business models in Brazil. However, at first glance, the single-user could already be deployed (renewables + battery).

Are smart grids a barrier to development in Brazil?

Although there have been some advances in the Brazilian regulatory structure, many gaps still stand as a barrier to the development of smart grids. Smart grids are expected to be at an intermediate level of development in Brazil by 2030 ( Carvalho, 2015 ).

How can microgrids reduce investment costs in Brazil?

In Brazil, the development of financial mechanisms for DG, the Green Fund and some sectorial funds can leverage the creation of mechanisms that could reduce the high investment costs for microgrids. Market challenges include the participation of microgrids in the market so they are able to sell their products and services.

How to promote DG and microgrids in Brazil?

Besides, issues such as tariff structure and distribution planning could promote DG and microgrids in Brazil. The microgrid could be subject to a flat buying and selling electricity rate or to a varying rate with time (Time-of-Use - ToU) for buying and selling electricity. In order to stimulate microgrids, the ToU tariff could be important.

Are microgrids a good idea?

Microgrids, perhaps the most promising novel grid structure, are presented as a way of expanding such technologies, with the potential of mitigating or eliminating negative effects, and even allowing their organized expansion and the improvement of benefits.
