Power control strategies during voltage sags according to Spanish grid code [PDF]
, 2018 In order to connect any power converters into the grid there are some grid requirements to insure the safe operation of the grid. So, the control of the converters especially during abnormal condition e.g. during voltage sags is

Redispatching Active and Reactive Powers Using a Limited Number of Control Actions [PDF]
IEEE Transactions on Power Systems, 2011 This paper deals with some essential open questions in the field of optimal power flow (OPF) computations, namely: the limitation of the number of controls allowed to move, the trade-off between the objective function and the number of controls allowed to move, the computation of the minimum number of control actions needed to satisfy constraints, and ...

IET Generation, Transmission & Distribution, 2020 The photovoltaic (PV) hosting capacity of active distribution networks is usually restricted by network overvoltage at peak PV generation hours. In the literature, several methodologies are presented to mitigate this problem caused by PVs reactive power ...

Abstract Phase-space Networks Describing Reactive Dynamics
, 2013 An abstract network approach is proposed for the description of the dynamics in reactive processes. The phase space of the variables (concentrations in reactive systems) is partitioned into a finite number of segments, which constitute the nodes of the ...
