“…It is also similar to the rectifier analysis in [6]. In most of the research articles, derivation or ZSCC cancellation has been carried out for two inverters or APF sh units [7][8][9][10][11]. Moreover, the control methods discussed in the literature are mainly for PWM based control system.…”

“…But it then raises the control complexity by introducing the zero-sequence circulating current (ZSCC) flow within the APF sh units which can overload the inverters of the APF units and thus increases the power losses. Other problems associated with the ZSCC flow is that it can reduce the ampacity (capacity of carrying current) of the cable, it can increase the DC link voltage, and it is harmful for the DG system like DFIG application [4][5][6][7][8].…”

Capacity enhancement and operational flexibility are two of the important limitations of the centralized shunt APF (APF sh ) unit. These limitations can be conquered by the operation of multiple APF units in parallel and connected back to back by a common DC link capacitor. In that case, a circulating current (CC) flows within the APF sh units. This CC flow becomes out of control when the APF sh units operate in hysteresis based current controlled mode. One of the difficulties of this CC flow control or reduction is the variable switching frequency of the APF sh units. In this paper, the model for CC flow is derived by the switching dynamics study of the APF sh units. It is found that the selection of design parameters plays an important role in the amount of CC flow. Detailed simulation, analysis, and real-time performance show how the selection of design parameters affects the CC flow and the reduction of CC flow can also be achieved at an acceptable level by the proper selection of design parameters.

“…Until recently, four-wire unbalanced stand-alone systems fed by DFIG have not received much attention. One exception is [12], where the use of a four-leg GSC is proposed to provide a path for the load neutral current to avoid voltage distortion at the load. Nevertheless, in [12] the full advantage of this new degree of freedom is not exploited, since the modulated voltage of the fourth leg is kept constant at half of the dc-link voltage.…”

Nevertheless, in [12] the full advantage of this new degree of freedom is not exploited, since the modulated voltage of the fourth leg is kept constant at half of the dc-link voltage. In the present work, a neutral connection to the machine is provided in order to naturally achieve sinusoidal balanced voltages at the load, and the four-leg inverter is used to balance the stator current of the generator by means of the active modulation of the fourth leg in order to improve the dc-link utilization.…”

Artículo de publicación ISIThis paper presents a topology for a three-phase generation system for an isolated unbalanced load fed by a doubly fed induction generator with a neutral wire to include single-phase loads. The challenges of unbalanced loads connected to the system are presented along with a proposal for mitigating current imbalance by employing a four-leg rectifier. The proposed compensation method is based on the sequence decomposition analysis, and thus, it is based on previous works that use current control in double synchronous reference frames. Nevertheless, a conceptual analysis is presented that vindicates the use of resonant controllers in the stationary abc frame.Fondecyt 112068

This manuscript proposes an Internet of Things (IoT) platform for energy management (EM) in multi‐microgrid (MMG) system to enhance the power quality with hybrid method. The proposed method is the consolidation of opposition based crow search optimizer (OCSO) and radial basis functional neural network (RBFNN), hence it called RBFNOCS technique. The main aim of this manuscript is to optimally managing the power and resources of distribution system (DS) by constantly track the data from IoT‐based communication framework. In the proposed work, every devices of home is interfaced with data acquisition module (DAM) that is IoT object along unique IP address resultant in large mesh wireless network. Here, the IoT‐based communication framework is used for facilitating the development of a demand response (DR) energy management system (EMS) for distribution system. The transmitted data is processed by RBFNOCS technique. By utilizing the RBFNOCS method, the active with reactive power processing for optimal capacity unbalance compensation smart VSIs share the obtainable neutral current (NC). Likewise, the DS IoT framework enhances these networks flexibility and gives feasible use of obtainable resources. Moreover, the RBFNOCS method is responsible for satisfying the total supply with energy demand. The proposed model is activated in MATLAB/Simulink site and the performance is compared with existing models, namely improved artificial bee colony, squirrel search algorithm and gravitational search algorithm based artificial neural network (SOGSNN), GOAPSNN, fruit fly optimization, and FORDF technique. When compared with the existing methods, the efficiency of the RBFNOCS method is 93.4501%.
