ABB’s microgrid to power Aruba


The island of Aruba plans to cover half its annual energy need using renewable energy sources and the other half using alternative fuels by 2020. To achieve this goal, they trust on an advanced microgrid solution, provided by ABB. The system will will help WEB Aruba, the islands main power utility, integrate solar and wind energy, forecast and plan better and optimize operations in real-time.

Aruba is a popular tourism destination in the Caribbean. It has a peak demand of 134 MW currently met by a mix of thermal, wind and solar photovoltaic generation. To integrate the complex energy generation portfolio in the best way possible and to maximise the use of renewable energy the WEB Aruba N.V., Aruba’s main power utility, has decided to rely on a microgrid solution by ABB. Using 24 hour forecasts of both renewable output and system load, the system will help plan operations and adjust dispatch in real-time to accommodate changes in renewable output, load or generation availability. This leads to a more automated grid.

At the heart of the solution is an advanced control system with dynamic load shedding capability. When major system transients occur, that the generation and storage are not able to accommodate, the system immediately calculates the minimum load shed required to stabilize frequency. It also ensures the distribution of load shed events so that no critical facilities are impacted.

ABB is a well renowned company in microgrid technology with around 40 installations all over the world, across a diverse range of applications serving remote communities, islands, utilities and industrial campuses.
