“…The quantity of offshore wind power generation is on the increase in the UK. Wave power generation can also have a significant contribution if properly harnessed [3]. The UK has a target of 15% renewable energy consumption by 2020 which translates to a 29 GW contribution from offshore wind power [4].…”

This paper centres on the performance of PI and hysteresis controllers for AC fault ride through for an MMC VSC -HVDC transmission system. In the simulated MMC converter test system, a 600 MW VSC-HVDC transmission line connects two farms, formed from combined offshore wind turbines and wave converters, to the two onshore AC grids. The model in this study included two 300kV DC submarine cables with a cable length of 100km. In the reported simulation a three-phase to ground fault, a single line to ground fault, a double line to ground fault and a line-to-line fault were applied to the onshore AC network. The simulation results reveal reductions in DC voltage overshoot and transient energy with the PI-based controller (compared to the hysteresis controller) for 3-phase to ground, line to ground and line -to -line to ground faults respectively, with no difference for line-to-line faults.

“…Many efforts are in commercial development and simplifying the mechanical complexity [7,8]. There are reported studies about the regulatory and economic aspects of wave parks [9][10][11] and also about grid integration issues [12][13][14] and control strategies [15]. In [16] there is an analysis of the power quality for a particular case of a grid-connected wave park, no energy storage is used and the authors study the effect of aggregating models.…”

In this study, a wave park is analysed from the economic and electrical points of view. The system under consideration goes from each wave energy unit up to the point of common connection with the main grid. Time series are obtained from simulation models for a scaled prototype and include data for mild, medium and strong sea states. The simulation models have been validated against the small scale tank testing of a prime mover, a wave rider buoy and a scaled testing of the power take-off in a land-based test rig. The design of the proposed wave park layout aims to minimise its cost and power losses. A life-cycle analysis of the park is performed showing that around 30 €/MWh will be the share of the electricity price required to install and operate the wave park grid. The power quality of the wave park and its compliance with regulations are also analysed. Special emphasis is put in the study of flicker emissions concluding that the proposed wave park is within the grid code limitations and even a reduction of a 66% in the flicker coefficients is reported when considering the aggregation of several units in one model.
