Forecast integration into hybrid plant controls

Our colleague Olivier Liandrat recently presented our advances in short-term forecasting for microgrid applications at the Hybrid Power Systems Workshop 2019 in Crete, Greece.Integrating Renewables into MicrogridsPV-Diesel hybrid plants have been established as one choice for the electrification of isolated and remote communities and off-grid plants for C&I applications. PV energy reduces the costs while diesel compensates the PV variability risk. In our research project,

How Renewables change the face of a tropical island

Thanks to the government’s strategy and financial incentives, the energy market on Reunion Island is changing rapidly towards a more sustainable future. Today, more than 60% of the island's homes have solar water heaters installed on their roofs. Since the early 2000’s, public policies have largely incentivized photovoltaic solar energy in Reunion Island, making it a test lab for renewables - on- and off-grid. Reunion

‘Understanding Clouds’ – World Meteorological Day

'Understanding Clouds' was the theme of World Meteorological Day 2017 (on 23/03) to highlight the enormous importance of clouds for weather climate and water. Clouds are central to weather observations and forecasts. Clouds are one of the key uncertainties in the study of climate change. Clouds play a critical role in the water cycle and shaping the global distribution of water resources. Have a look

Towards a single energy market in Europe

In the frame of the integration of national energy markets, European institutions show a willingness to encourage the harmonization and the liberalization of the EU internal energy market. To do so, the interconnection of the national electricity grids is a tremendous lever that give energy market players numerous opportunities, with several advantages for the end user. The advantages of a Single Energy Market are divided

How the solar eclipse challenged the electricity grid in La Réunion

On September 1st, 2016, Reunion Island was on the front row to witness an extraordinary astronomical show: an annular eclipse. How did this rare event impact the photovoltaic generation, and the management of the local power grid? The Moon gradually blotted out the Sun in the morning of September 1st, successively casting its shadow from Equatorial Africa to the south of the Indian Ocean. Located

Case study: Lack of flexibility in European electrical systems leads to deteriorated grid management

How solar forecasting could avoid negative energy prices due to high renewable energy generation. The German market was affected on May 8th 2016 by an exceptional penetration of variable (solar and wind) renewable energy sources (RES) into the grid. The latter represented nearly 87% of the country’s electricity production, causing the occurrence of negative prices of about € -144.78 on the spot market throughout the

Smart City, the city of tomorrow

The world is moving towards a population more and more present in cities, with an increasing centralisation of business centres. This causes an increase in the number of inhabitants in these areas. Indeed, the United Nations announced that in 2030, two out of three people would live in cities. If nothing is done to adapt these urban areas, they will lead to inevitable economic and
