Abstract
Although the integration of renewable energies in power grids implies a more sustainable energy scenario, it also involves power quality problems associated with non-manageable energy resources. Ocean wave energy presents medium-long term power fluctuations (from hourly to seasonal) linked to climate, such as solar and wind energy. Moreover, wave energy conversion must also take into account the wide variety of wave energy converter (WEC) technologies available and the short-term generated-power oscillation from waves; and these power fluctuations may have an important undesired impact on the electrical grid. This paper presents a methodology to analyses the impact of these power oscillations in the electric grid and, specifically, the impact on its frequency. The analysis is based on the use of a single-bus inertial model to simulate the electric grid and in a WEC time domain model to obtain the wave farm (WFs) electric power profiles. A parametric analysis of the grid frequency deviations in a specific island has been carried out in respect of cases of: WEC positioning, incident wave angle, electric grid operating states (peak of valley consumptions zones), and sea states.
