TLDR
In this article, an approach to optimize the supply and usage of electricity over a shorter time frame is discussed to reduce the cycle length and dispatch period so that a greater number of loads can be served without increasing the power source.Abstract:
During about one third of the Space Station's orbit the solar array output is zero and the payload is served by storage devices It has been found that when a 24-hr cycle is used, some loads onboard the station cannot be scheduled during the desired times It therefore becomes necessary to reduce the cycle length and dispatch period so that a greater number of loads can be served without increasing the size of the power source An approach to optimize the supply and usage of electricity over a shorter time frame is discussed Supply/demand windows of various lengths are implemented for the typical load profile As a result fewer rescheduling tasks are needed and a closer match between the supply and demand is obtained The optimal supply/demand can be refined in terms of the excess and shortage of electricity This technique is implemented using PROLOG and FORTRAN >read more

Automatic management system of production and consumption of electricity.
TL;DR: In this article, the authors present a system for automatic management of the production and consumption of electricity, in which a site comprises equipment for power generation and aircraft, characterized by the fact that includes sensors (8) for measuring the amount of electricity generated by each device, actuators (9), and means of control that intelligently manage said autonomy and said reloading of each device by applying a virtual gauge which incrementing and decrementing its value is proportional a relationship between autonomy and loading time.
