The power system nonlinearity and its profound impact on the individual states of power system is first evaluated and the interaction between their constituent modes during the occurrence of internal mode resonance (IMR) is discussed in this paper. A typical dynamical feature of nonlinear systems is the frequency-energy dependence of their states and their corresponding constituent modes which ...

Schools play a vital role in creating a greener future. They will likely be the first place most students encounter determined efforts to conserve energy and water or to reduce waste. The method used in this article is comparative and matching method, by using ISO 14001, OHSAS 18001 and ISO 50001 standards.  Implementing energy management along with other standards is the main objective of pres...
