“…The uncoupling between

and

allows the distribution of the non-efficient current terms among the EGs present in the MG. The solution usually proposed in the literature consists of the inclusion of one shunt active power filter, as in [19] , [22] , although this solution requires an over-sized device that leads to over costs or a low use of the installed infrastructure capacity.…”

“…Evidence of the relative success of the EGs application as active agents in the non-efficient powers compensation can be found in the literature. Accordingly, developments for photovoltaic (PV) [18] , [19] , wind [20] , and battery energy storage system (BESS) combined with ancillary services for power quality improvement [21] , [22] have been presented. Although these papers report some improvements in power quality, the approach followed by most of them is to compensate all non-efficient powers in the MG from a single EG, without considering current or power limits in its output.…”

“…voltage and current control loops are shown in Figure 4, where Gbat is the transfer function of the battery converter expressed by (8), Gcbat is transfer function of battery current controller, Gcsc is transfer function of SC current controller, Gsc is transfer function of SC converter, Gv is transfer function of inductor current to the output voltage. The battery current control loop transfer function can be defined as (9). The PI-fuzzy controller is used in the dc-link voltage control loop to tackle the side effects of the HC operation of ILC [25,26].…”

“…In case of large nonlinear loads, harmonic content should be decreased using passive or active power filters which are an expensive solution, so ILCs can be effectively used to suppress harmonic currents imposed by nonlinear loads. The ILCs can contribute to voltage stability improvement [3,4], voltage unbalance compensation [5,6], flicker mitigation [7], harmonic compensation [8][9][10] and reactive power compensation [11] in MGs and distribution networks. As the number of nonlinear loads is growing rapidly in distribution systems, ILC harmonics compensation plays an interesting and important role.…”

Increasing nonlinear loads and power electronic converters lead to various power quality issues in microgrids (MGs). The interlinking converters (ILCs) can participate in these systems to harmonic control and power quality enhancement. However, ILC participation deteriorates the dc link voltage, system stability, and storage lifetime due to oscillatory current phenomena. To address these problems, a new control strategy for a hybrid energy storage system (HESS) is proposed to eliminate the adverse effects of the harmonic control operation of ILC. Specifically, battery and super-capacitor (SC) are used as HESSs that provide low and high power frequency load, respectively. The proposed strategy tries to compensate the current oscillation imposed by ILC with fuzzy control of HESS. In this method, a proportional-resonant (PR) controller integrated with harmonic compensator (HC) is employed to control the ILC for power quality enhancement and oscillatory current elimination. The main advantages of the proposed strategy are to reduce DGs power ﬂuctuations, precise DC bus voltage regulation for generation and load disturbances, improved grid power quality under nonlinear load and transition conditions. The performance of the proposed method for isolated and grid-connected modes is verified using simulation studies in the MATLAB software environment.

“…In [39], work was carried out with an i-µG, a C-HIL with an IT less than 1 µs to validate the controllers applied to a photovoltaic system, and a storage system using batteries. In [40], a C-HIL platform to validate the control strategies applied to a multifunctional converter was developed. In this platform, the controller was emulated in a dSPACE with a 6 µs IT.…”

Power Sharing Control in a Grid-Tied DC Microgrid: Controller Hardware in the Loop Validation

et al. 2021

View full text Add to dashboard Cite

This article presents the development of a low-cost control hardware in the loop platform for the validation and analysis of controllers used for the management of power sharing between the main grid and a DC microgrid. The platform is made up of two parts: a main grid interconnection system emulator (MGISE) and a controller under test (CUT). The MGISE operates on a 260 V DC bus and includes a 1000 W photovoltaic array, a DC variable load and a single H full bridge converter (HFBC). The CUT includes a phase locked loop and a main cascade control structure composed of two PI controllers. Both the MGISE and the CUT were embedded on an NI myRIO-1900 development board and programmed using LabVIEW virtual instrumentation software. These devices communicate with each other using analog signals representing the AC side current, the DC side voltage, and the HFBC control signal. The MGISE operates with an integration time of 6 µs and its performance is validated by comparing it with a simulation in PSIM. The integration time of the MGISE, the development boards used, as well as its programming environment, and the results obtained from the comparison with PSIM simulation, show that the proposed platform is useful for the validation of controllers for power sharing, with a simple implementation process compared to other hardware description methods and with a low-cost platform.
