"After widespread power cuts across most of Spain and Portugal in April, the National Energy System Operator (Neso) started work to pinpoint dangerous fluctuations that could lead to outages. The Iberian peninsula suffered a series of disturbances that caused power plants to disconnect from the network. An official report on the cause of the incident, in which system voltage collapsed to zero, is expected later this year."
"Craig Dyke, the director of operations, said: Even though Great Britain has one of the most reliable networks in the world a record Neso, network operators and the whole energy industry work tirelessly to maintain exploring every opportunity for learning and improvement is essential. Indeed, Neso would be guilty of complacency if we did not reflect on what happened in April, even though the GB network was unaffected."
Great Britain’s energy system operator upgraded real-time monitoring to detect dangerous grid fluctuations and future-proof a low-carbon power network. Widespread power cuts across Spain and Portugal in April caused generation units to disconnect when system voltage collapsed to zero, leaving many households and businesses without electricity for almost two days and disrupting internet, mobile networks and major events. The incidents exposed balancing challenges for renewables-heavy systems compared with thermal-dominated grids. Neso is deploying a new mathematical methodology to spot problems that could lead to outages and is developing protocols to restore nationwide power within five days, aiming to meet the government mandate by the end of next year.
