Slide 6: RoCoF must be addressed to keep the power system stable
INERTIAL THE RATE OF CHANGE OF FREQUENCY (ROCOF) MUST BE ADDRESSED TO KEEP OUR RESPONSE POWER SYSTEM STABLE – VARIOUS STRATEGIES CAN BE DEPLOYED. THE CHALLENGE THE SOLUTION MATCHING SUPPLY AND DEMAND, IN THE BLINK OF AN EYE LEARNING HOW TO ROCK THE ROCOF Keeping the grid stable means matching supply
Slide 7: Analogue inertia from synchronous generators versus digital inertia from batteries
INERTIAL UNDER THE STATUS QUO, ‘ANALOGUE INERTIA’ FROM SYNCHRONOUS GENERATORS RESPONSE HELPS MANAGE ROCOF, BUT BATTERIES PROVIDE AN EXCITING ALTERNATIVE SYNCHRONOUS GENERATORS BATTERIES ANALOGUE INERTIA DIGITAL INERTIA HOW DOES IT WORK? Batteries are not grid-synchronised and have no moving parts. T
