The need to restore and keep the grid running or fast restoration during emergencies such as extreme weather conditions is quite apparent given reliance of other infrastructure on electricity. One promising approach electricity use locally available energy resources system form isolated microgrids. In this paper, we present a black start method that forms islanded microgrids after blackout. mas...

This paper addresses the detailed modeling and small-signal stability analysis of a multi-terminal high voltage direct current (HVDC) system including large diode rectifier-connected off-shore wind power plant (WPP). The study covers both islanded connected WPP operation with different control scenarios. Islanded stands for non-conducting HVDC rectifier (DR) whereas in DR is conducting. modes i...

Abstract Motivated by the recent paper of Boggiatto–Garello (J Pseudo-Differ Oper Appl 11:93–117, 2020) where a Gabor operator is regarded as pseudodifferential with symbol $$p(x,\omega )$$ p ( x , ω ) ...

‘Separable’ uncertainty sets have been widely used in robust portfolio selection models (e.g. see [E. Erdoğan, D. Goldfarb, and G. Iyengar, Robust portfolio management, manuscript, Department of Industrial Engineering and Operations Research, Columbia University, New York, 2004; D. Goldfarb and G. Iyengar, Robust portfolio selection problems, Math. Oper. Res. 28 (2003), pp. 1–38; R.H. Tütüncü a...

Maximum power point tracking (MPPT) of a photo voltaic system with different temperature and insolation conditions used for Micro grids can be explained in this paper. The micro grid conception permits small distributed energy resources (DERs) to act during a coordinated manner to produce a necessary quantity of active power and supportive service once needed. This paper proposes an approach of...
