Case study: helping renewables onto the UK network - Renewable Energy Focus

Adding renewables to the network affects the load on the grid causing more intermittent loads, heavier loads or even reverse power flows. This causes problems such as: Overvoltage : when the voltage is higher than required for equipment to operate most effectively. This causes a reduction in equipment lifetime and increases energy consumption with no improvement in performance; Undervoltage : when the voltage is lower than required for equipment to operate most effectively. This may lead to premature equipment failure, failure to start and increased temperature. Both over and under voltage conditions in the extreme can result in disconnection of the local power generating devices themselves from the grid, exaggerating the issues further; Poor power factor : power factor measures how effectively the current is converted into useful work output. A low power factor means that...
