This paper presents a coordinated approach for the tuning of power electronic controllers and stability analysis considering constant power load in a DC microgird. The system consists of AC and DC loads, comprising of constant voltage and constant power characteristics. Constant power loads can be a potential source of instability for the system to which it is connected. Coordinated tuning of all...

This paper presents the power management scheme of PV based islanded microgrid using battery and supercapacitor hybrid energy storage under dynamic load conditions. The energy management scheme employs hysteresis controlled bidirectional dc-dc converter for battery and supercapacitor. The constant power fluctuations are compensated using battery as energy buffer while transient power fluctuations...

Nonlinear model of hydroelectric turbine model with elastic water column in penstock consider the effects which cause travelling waves: pressure and flow due to elasticity of steel in penstock and compressibility of water. This paper proposes two nonlinear electrical analogue turbine models of hydroelectric plants, non-dissipative model and approximated model. Dynamic response of the proposed model...
