“…As the wave energy resources are lower in this region of the North Sea [21], lower penetrations levels of wave power are also expected due to the definition of metric NFES. The complementarity index of all three combined sources based on [22] and [23] is shown in Fig. 4d).…”

The paper investigates the added grid value of co-locating wave energy converters with offshore wind turbine generators and floating photovoltaic solar panels. Grid value is evaluated in terms of power generation variability and electrical infrastructure utilization. Using meteorological reanalysis data for the region of the North Sea, wave, solar and wind energy converters are modelled on an hourly basis to form the power profile of the joint operation. Necessary power ratings of the transmission system are provided both for stand-alone installations and the hybrid parks and is shown to be of higher utilization for the latter case. Suitable locations of hybrid parks are also analyzed and provided in terms of water depth, solar irradiation and favorable wave and wind climate. The joint operation is found to smoothen the power profile on all time scales but influences long term variations most heavily. Added grid value strongly depends on the park configuration as well as metocean conditions. It is shown that by co-locating wave, solar and wind energy converters the utilization of the electrical transmission system is increased compared to stand-alone installations.

“…Much of the work is focused on assessing and quantifying the complementarity behavior of the energy sources, commonly using correlation coefficients, normally restricted to two sources. In [6] a method was presented to assess the complementarity of three sources using correlation coefficients, later improved in [7]. Other common metrics employed to assess complementarity are e.g.…”

An important aspect in designing co-located wind and solar photovoltaic hybrid power plants is the sizing of the energy converters to achieve as efficient power smoothening as possible. In this study, the ratio of wind-and photovoltaic energy converters in a hybrid power plant is determined by minimizing the overall stored energy that is needed to facilitate constant power output. Using Fourier transform the variability is isolated at predefined time scales that are relevant for grid integration. For the investigated time scales, energy and power ratings for energy storages are determined to counteract the variability. The resulting configuration is the one that is able to achieve constant power output with minimum stored energy. It is shown that co-locating wind-and photovoltaic energy converters smoothen seasonal energy generation, and reduce the energy storage need in both the diurnal and seasonal time scales. A case study for south-eastern Sweden is presented where the wind-& solar hybrid plant configuration that minimizes the energy storage need and therefore most closely resembles constant output power is determined. It is found that a ratio of approximately 40-45% wind power in the hybrid power plant yields the lowest need for energy storage. The presented method is valid for any number of co-located energy sources, and can also be extended to sizing of hybrid power systems.
