This paper deals with the performance of a heat pipe solar collector. The solar collector consisted of an interconnected heat pipe so as to reduce the production cost by using an interconnected heat pipe because all the heat pipes can be evacuated, sealed and tested at once. Performance of a prototype of the heat pipe solar collector was experimentally examined, and the results were compared wi...

In recent decades, microgrid systems have included renewable energy sources due to insufficient power generation. However, uncertainty in the output of and load change an effect on system frequency, affecting microgrid's ability operate reliably. For continuous electric power, intelligent controller is essential improve stability. This paper proposes construction a cascaded Modified Differentia...

Newly developed tools and techniques are continuously established to analyze monitor power systems’ transient stability limits. In this paper, a model-based index for each generator is proposed from the synchronizing torque contributions of all other connected generators in multi-machine interconnected system. It new interpretation generator’s coefficient (STC) terms electromechanical oscillati...
