Development of A Hierarchical Saving Power System for Campus

Saving power is the major goal in every area either in industry or in campus. However, there are more uncertainties in campus. For instances, the usages of air conditioners in the classroom are irregular events. In the other hand, the lighting in the parking area is the regular event. For the regular event, we use the unstable green energy like wind or solar to save the electric cost. For the irregular event, we use the stable electricity but managed by dynamic power dispatch system to efficiently handle usages of air conditioners in the classroom in order to reduce cost. This dispatch system is the integration of Internet, network, coded radio frequency, database, interfacing technology, and campus administration computerization servers. By using the existing media and devices, the set-up of this system is without extra expensive cost. This hybrid strategy is simulated in a university with about 15000 students and more than 100 classrooms equipped with air conditioners. We can estimate to save more than 10% power than usual.
