“…As illustrated in Figs.1&2, this paper proposes to decouple all SGs from the network by a set of AC/DC/AC PECs, namely: network side converter (NSC) and generator side converter (GSC). This paper also proposes an updated version of the control algorithm in [28], [34] (which is illustrated in Fig.3) to control the NSCs of SGs and other CBSs. All the PECs (NSC, GSC and DERs) are controlled using the classic current-controlled VSC in dq-frame (using PI controllers).…”

This paper proposes a new paradigm in the structure of power systems to facilitate the large scale move to renewables-based distributed generation necessary to help decarbonize the current electricity networks. Since the design of the incumbent power system topologies is to control large synchronous generators, critical control metrics degrade as the penetration of converter-based units increases. Specifically, the reduction in short circuit level, phase angle movement, and rate of change of frequency limit the wider adoption of converter-based units. This paper proposes structural changes and control that inherently solve such critical performance issues through physically decoupling all synchronous generators from the network. A set of back-to-back AC/DC/AC converters controlled by a universal virtual synchronous machine-based control algorithm, introduced in the paper, allows the repurposing of existing plant to enable the integration of more converter-based units. Despite being physically disconnected, this new structure/control still benefits from inertial capacities of synchronous generators to suppress the oscillations caused by disturbances. Moreover, the method enables further exploitation of synchronous generators as energy storage mechanisms. PSCAD/EMTDC simulations demonstrate the advantages of the proposed structure and control system in different normal and abnormal scenarios.

Summary This article proposes an adaptive and modified Perturb and Observe (P&O) maximum power point tracking (MPPT) algorithm, using fuzzy logic step size controller, for a wind energy conversion system (WECS) based on wound rotor synchronous generator. The modified P&O controller uses additional current information of the dc‐link, to decrease power oscillation around MPP, and choose the correct direction of the perturbation, while wind speed increase condition, depending on the sign of dc‐link current change. So, in this contribution, a modified drift‐free P&O algorithm was chosen because it gives better results, but the duty cycle step size in the proposed MPPT controller has been varied adaptively, using a fuzzy logic inference system based on the variation of the rectifier output power and the previous change of the duty cycle to get fast convergence until the MPP is reached in increasing and decreasing wind speed conditions. Performances and robustness of the proposed speed sensorless MPPT controller are evaluated in an experiment implementation, using a WECS emulator and dSpace DS1104 controller board, where experimental results show that the proposed method guarantees fast convergence with better energy quality and high robustness against speed or load change conditions.

A new control strategy for a wind-BES (battery energy storage) microgrid is presented, which controls the power transfer and the mode of operation seamlessly from an islanded mode (IM) to the grid connected mode (GCM) and vice versa. In GCM, the DC link voltage regulation, the load reactive power compensation and harmonics current mitigation are performed by the load side voltage source converter (LVSC) using a double sinusoidal signal integrator (DSSI) based control algorithm. The maximum power from the wind generation is extracted by operating the generator side voltage source converter (GSC). At the grid fault or grid disturbances, this microgrid operates in IM and LVSC is controlled in the voltage control mode. A synchronizing controller is utilized to control the operation of synchronization. The grid current and point of common coupling (PCC) voltage distortions are kept within the limit as per the IEEE-519-2014 and the IEEE-1547 standards. The system operation is demonstrated through test results at several conditions such as, changing wind speeds, varying loads and seamless transition. 1 INTRODUCTION The contribution of renewable energy sources (RESs) in the power generation is increasing to meet the growing demand and to replace the existing conventional sources of energy, i.e. fossil fuels, which are towards depletion [1-5]. RESs are freely available in nature, and clean source of energy. The RESs with a battery energy storage (BES), forms a microgrid (MG), which works in an islanded mode (IM) and the grid connected mode (GCM) along with seamless transition with continuously supplying the loads without interruption [6]. A power interruption to the loads, may lead to damage, malfunctioning and important data loss etc. In RESs, depending on its output supply, i.e. AC or DC, one or more power converters are required to interface the MG to the utility grid. Along-with the power generation, the MG has the capabilities of supplying an active power to the utility grid. It improves the power quality (PQ) in terms of active filtering and compensates the reactive power demand of the load [7, 8]. The wind energy for the power generation is gaining popularity due to continuous improvement in the generator and power converter technology.
