Offshore Wind Farm Power Control Using HVdc Link

Improving fault ride through capability of induction generator‐based wind farm using static compensator during asymmetrical faults

“…The coefficients c 1 À c 9 are different for various wind turbines and are selected as listed in Table 1. 31 1…”

“…These systems can also increase the efficiency of the power grid in active power flow as well as better stability of the power grid. 31 The STATCOM is a shunt reactive compensator device that can produce or absorb reactive power into the grid to improve the power quality of the grid. The identical circuit of the STATCOM is outlined in Figure 2.…”

Hybrid cuckoo search algorithm and grey wolf optimiser‐based optimal control strategy for performance enhancement of HVDC‐based offshore wind farms

“…In PMSG, a gear box is not required and the generator's stator connection with the grid is conducted through a fully rated converter [7,8]. Although, this kind of generator is characterised by the expensive materials of permanent magnet and its large outer diameter, which offers a number of advantages that make it a good choice for VSWT applications such as low weighing and compact size [9,10]. Over and above, PMSG type is more efficient, less maintenance, more reliable, and no extra supply for magnetic field excitation [4,6,11].…”
