intermittent

 [in″ter-mit´ent]
marked by alternating periods of activity and inactivity.
intermittent claudication a group of symptoms characterized by pain, cramping, and weakness in the calf muscles of one or both lower limbs, brought on by walking and relieved by resting for a few minutes. It is a form of arterial occlusive disease and is caused by atherosclerotic lesions of the limbs, which diminish blood supply to the muscles of the lower leg. Called also angina cruris.

Treatment has traditionally involved vascular reconstructive surgery to bypass the diseased portion of the vessel. Modification of risk factors has also proved beneficial, such as smoking cessation, weight loss, and introduction of a graduated program of walking and exercise.
intermittent explosive disorder a rare impulse control disorder in which a periodic loss of control of aggressive impulses results in serious assault or destruction of property; the outbursts are totally out of proportion to any apparent stress.
intermittent positive pressure breathing (IPPB) a form of respiratory therapy using a ventilator for the treatment of selected patients with atelectasis, those needing occasional assistance breathing, or those requiring some types of aerosol medications. As the name implies, this involves application of pressure only during the inspiratory phase, in order to help the patient breathe more deeply. It is used when other less expensive, less invasive forms of respiratory care have not been effective. Called also intermittent positive pressure ventilation.

Because of their compact size and capability of operating independently of an electrical current, IPPB machines are used widely. Similar treatment can also be delivered with a volume-, pressure-, or time-limited ventilator or manual resuscitation device. The American Association for Respiratory Care has published detailed and comprehensive clinical practice guidelines for the use of intermittent positive pressure breathing, which are available online at http://www.rcjournal.com/online_resources/cpgs/ippbcpg.hotmail.

At first, utilities ignored government efforts to encourage RE deployment; later, they began to lobby against them, as they realized that managing the problem of intermittency would be both technically difficult and expensive, and that hard assets such as coal and nuclear plants were being rendered worthless.
The series inverter is responsible for compensating the voltage sags and swells and the shunt inverter is responsible for active/reactive power support and renewable intermittency smoothing.
Solar's intermittency will add to this problem, since coal and gas plants will often be needed as backups for when the sun isn't shining.
Intermittency is a major issue because the source of renewable electricity can drop almost instantly and unpredictably, but the shortfall cannot be easily caught by traditional fossil fuel-fired power stations, which need time to load up and are much less efficient on light load.
