TL;DR: In this article, a theoretical explanation of the supercritical boilerturbine-grid control relation is presented using the results of computer simulation studies, and the tuning flexibility of modern control systems is examined from the standpoint of the effects on the stability of grid frequency.
Abstract: A theoretical explanation of the supercritical boilerturbine-grid control relation is presented using the results of computer simulation studies. The energy storage behavior of an isolated steam-electric grid is described, and the tuning flexibility of modern control systems is examined from the standpoint of the effects on the stability of grid frequency.

TL;DR: The solar array power system placed into a sunsynchronous orbit on the SERT II (Space Electric Rocket Test) Spacecraft was capable of providing over 6 X 10 whr of electrical energy over a period of 6 months as mentioned in this paper.
Abstract: The solar array power system placed into a sun-synchronous orbit on the SERT II (Space Electric Rocket Test) Spacecraft was capable of providing over 6 X 10 w-hr of electrical energy over a period of 6 months. The 56-v, 1100-w sectionoutput is provided directly to a powerconditioning unit with no batteries in the system. The 28-v, 180-w section provided the power to the spacecraft for housekeeping and auxiliary experiments. The deployment technique, which uses springs in each leaf joint to extend the folded array into a flat fixed position, and redundant electrical pyrotechnic circuits to enhance probability of deployment, is discussed.
