- [Narrator] This Russian oil tanker has just arrived in Cuba. It's the country's first oil shipment in more than two months, and a relief from President Trump's oil blockade. - If a country wants to send some oil into Cuba right now, I have no problem with it.- But the White House says its policy hasn't changed, and the tanker's 730,000 barrels of crude oil will not solve the energy crisis in Cuba, where people have endured seven island wide blackouts in the last year and a half alone. Here's why Cuba's en ...

Grid Infrastructure Challenges with Renewable Energy - Renewable energy sources like wind and solar are creating infrastructure problems because power grids weren't designed for them [1] - The lack of inertia in renewable energy systems can increase the risk of widespread blackouts [5] - Conventional power plants have built-in inertia, providing buffer time when a power plant fails [2][4] Solutions for Grid Resilience - Grid-forming inverters can operate independently and support the grid during disruptions [5][6] - Synchronous condensers can provide additional rotational inertia by using electricity from renewable sources [7] - Battery energy storage systems (BESS) can deploy excess energy to stabilize the grid during outages [8] Technological Aspects - Conventional power plants produce electricity at a grid frequency of 60 Hz in the US [3] - Grid-following inverters rely on the grid's voltage and frequency, while grid-forming inverters can adjust electronically and react faster [5][6]
