In a microgrid connected with both intermittent and dispatchable sources, intermittency caused by sources such as solar wind power plants can be balanced dispatching hydro into the grid. Both generation consumption are stochastic in nature, not known perfectly, require future prediction. The will cause grid frequency to drift away from required range. To improve performance, operation should op...

The present paper demonstrates a proof-of-concept by introducing variable guide vane system in the draft tube of high-head Francis model turbine. aim is to examine hydraulic performance turbine while mitigating pressure pulsations tube. vanes can rotate about an axis up ±45°. mitigation studies were performed at lower- and upper-part loads. was examined all operating ranges within head. There s...

Using hydraulic energy from irrigation flows to become electrical as renewable still needs be conducted. Therefore, this research aims design a pico hydro turbine building powered by water and its tests analyses. The has been simulated with the CFD (Computational Fluid Dynamics). method used in study is solver approach simulation which analyzed flow s imulation applications using kinetic equati...
