ABB will provide an advanced microgrid to WEB Aruba N.V., the main power utility serving the Dutch Caribbean island of Aruba. ABB’s software, automation and control technologies will help WEB Aruba integrate solar and wind energy, forecast and plan better and optimize operations in real-time, while meeting Aruba’s growing demand for electricity.
The island is 32 km long and 10 km across its widest point. It has a land area of 179 square km and a population of about 103,000 inhabitants. A popular tourism destination, Aruba has a peak demand of 134 megawatts currently met by a mix of thermal, wind and solar photovoltaic generation. The utility has set a goal to generate half its annual average energy supplied from renewable energy sources and the other half from alternative fuels by 2020, supporting the government’s vision to become completely fossil-fuel free.
ABB’s microgrid solution allows for integration of a complex energy generation portfolio and maximizes the use of renewable energy, while optimizing operations in real-time. 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.
“This innovative microgrid solution will support the island of WEB Aruba to integrate more renewables and maintain reliability and efficiency of power supplies to meet increasing demand for electricity”, said Massimo Danieli, head of ABB’s Grid Automation business, a part of the company’s Power Grids division. “The embedded software, automation and control technologies will also facilitate 24 hour forecasts and enable a stronger, smarter and greener grid.”
