Energy management systems (EMSs) have been introduced in electrical power to optimize operations of the grid infrastructure and provide support operator terms optimized decisions [...]

In order to conduct a data-driven load forecasting modeling and its application in optimal control of air-conditioning system, this study used hotel’s central air conditioning system as the research object. Based on data hotel energy management load-forecasting model based support vector regression (SVR) was established by MATLAB. working principle chiller, chilled water pump, cooling tower, co...

The replacement of conventional generation sources by DER creates the need to carefully manage reactive power maintaining system safe operation. principal trend is increase volume connected distribution network in coming years. Therefore, microgrid represents an alternative offer management due excellent controllability features embedded DER, which enable effective interaction between and netwo...

Low-frequency high-voltage alternating-current (LF-HVac) transmission scheme has been recently proposed as an alternative solution to conventional 50/60-Hz HVac and direct-current (HVdc) schemes for bulk power transfer. This paper proposes optimal planning operation loss minimization in a multi-frequency system. In such system, LF-HVac grids are interconnected using back-to-back (BTB) converter...

The paper proposes multi-operation blank localization to fit final product geometries into near net shape blanks. Groups of machining features are located subject tolerance intervals on their relative positions and a lower bound the allowance which accommodates for uncertainties measurement machining. error, i.e., deviation resulting dimensions from center is minimized. problem formulated as co...

Dividing Wall Column(DWC) offers the large potential for operating and capital cost saving in compared with conventional distillation sequence. In the studied DWC in this study, the aid of Vmin diagrams, it is shown that without a suitable value for vapor split fraction bellow the dividing wall in different operating conditions, the energy requirement increases from optimal value and it wil...
