The penetration of wind energy in power system is growing dramatically world wide. Consequently, there are some new challenges appeared on power system. Smart demand technology involves new communication technologies to make sure actions can be fast enough to prevent instability situation of generators. Due to the high level of renewable energy in power system, flexible demand becomes a future option for wind intermittency situation. Intertrip is one of the automatic actions that can help release overload and stability situation. It is normally used for generations to be disconnected followed by a trip of circuit. It can also be used for demand side intertrip. This paper will show how demand disconnection and intertripping technology can improve power system stability. Power Transfer Distribution Factor (PTDF) will be used to define wind transfer corridor circuits. After the corridor is located, the sensitivity of individual demand will be calculated by using PTDF method. This sensitivity factor will be used to select demand intertrip accordingly. It is defined as smart intertrip controller in the paper. A reduced UK model will be used in the paper to prove how demand side intertrip technology can improve system stability during high wind scenario.
