“…These trends build a hybrid concept in terms of operation environment which has an advantage of not only the structural efficiency of transmission system but also the power utilization [31]. When composing a combine system with the wind-energy systems in the offshore regions, in particular, the tidal linear generator is being aggressively considered as a suitable cooperating device owing to their effectiveness and popularity [32].…”

For developing a large-scale combined system with a number of distributed resources, an appropriate compensation strategy based on the system components and changeable condition must be configured to handle the characteristics of the internal systems. Since renewable sources generate various fluctuations, the compensation plans for the storage device connected along with the sources should be supported by a precise expectation method. A cooperative strategy involving the sharing of the DC section with environmentally sensitive generators, like photovoltaic system (PVs) or waves, demands appropriate ESS compensation solutions, owing to its complexity. An active power-control algorithm with voltage-expectation based on the DC power flow is introduced in this paper and is applied in the designed case studies performed on the electromagnetic transient simulation. DC based multi-generation system is composed by applying tidal generator and super capacitor. To utilize wind energy, an offshore wind-wave generation system was utilized in the verification process.

This paper presents the stability and power-flow control results of a multi-machine power system connected with a hybrid offshore wind farm (OWF) of 160 MW through a unified power-flow controller (UPFC). The q-d axis equivalentcircuit model is employed to establish the complete system model of the integration of the hybrid OWF, UPFC and the multimachine power system under three-phase balanced loading conditions. Steady-state performance of the proposed UPFC on power-flow control of the studied system is evaluated. Transient simulation results under a three-phase short-circuit fault are also performed. It can be concluded from the simulation results that the proposed UPFC can achieve power-flow control and render damping to suppress oscillations of the studied multi-machine power system connected with the hybrid OWF under various operating conditions. Index Terms--Transient stability, power-flow control, multimachine power system, offshore wind farm, unified power-flow controller, transient simulations.

Abstract:A system that combines a wind turbine and a wave generator can share the off-shore platform and therefore mix the advantages of the transmission system construction and the power conversion system. The current hybrid generation system considers output limitation according to the instructions of the transmission system operator (TSO), and controls the profile using wind turbine pitch control. However, the integrated wave generation system utilizing a DC network does not adapt a power limitation scheme due to its mechanical constraints. In this paper, a control plan focusing on the electrical section of wave generators is formed in order to effectively manage the output profile of the hybrid generation system. The plan pays attention to power reserve flexibility for the utility grid using the analysis of the controllable elements. Comparison with the existing system is performed based on real offshore conditions. With the help of power system computer aided design (PSCAD) simulation, the ability of the novel technique is estimated by proposing the real power control based on the reference signal of TSO and the reactive power capacity it produces.
