Forecasting model to manage renewables-powered grids
Scientists in South Korea have developed a forecasting model to better manage electric grids with high penetration of intermittent renewables. The model was tested using historic data from Pennsylvania-New Jersey-Maryland (PJM) grid in the United States, and shown to accurately forecast the availability of renewable energy resources up to one day in advance.
‘There is no alternative to a world of 100% renewables’
Electrifying the global energy system with clean energy is the only way to reach the targets set by the Paris agreement on climate change and avoid the catastrophic scenarios outlined by the recent IPCC report. In an interview with pv magazine, Christian Breyer – Professor of Solar Economy at Finland’s Lappeenranta University of Technology – explains a 100% renewables model is not only technically feasible, but also the cheapest and safest option. With solar and storage at its core, the future energy system envisaged by Breyer and his team will not only stop coal, but also nuclear and fossil gas, while seeing solar reach a share of around 70% of power consumption by 2050. By that time, PV technology could cost a third of its current price.
