This paper proposes a sufficient method for the optimal operation and management of DC microgrids (MGs) in the presence of renewable energy sources (RESs), storage devices, and DC loads. The DC MG concept can not only exploit the distinguished features of DC distribution systems for feeding DC loads without the presence of AC-DC converters but also provide convenient connections for DC distributed...
Software reuse has long being recognized as an important area amongst the software development companies in improving productivity and quality of their product. Reusing of early-stage software artifacts such as UML state machine diagrams increases the benefit reaped from reuse because it allows the reuse of related later-stage artifacts. Among the reuse task, matching and retrieval of similar artifacts...
Ice load causes important faults on electric transmission lines (ETL), and power outages can be seen for days because of ice load. So, ice load effect must be prevented on ETL. One of the effect methods is Joule Effect Method (JEM). In JEM, ETL conductor is heated by current, and ice on conductor is melted. But primarily ice load amount must be determined to determine value of melting current. In...
Short circuits, voltage drop, harmonic distortion and power loss which is factors affect to power quality of power line as negative. Power line parameters affect to values of these factors. Therefore, power line parameters affect the quality of the electrical energy of transmission and distribution lines. Before new load is included to power line, power line parameters must be determined and so adversely...
