“…Here, it would be thought provoking to note that the proposed approach can be further extended to bring the overall VQ performance of the entire DN to common index instead of just being limited to individual buses. Moreover, the same idea has been realized by the authors of the present work in the work published in Reference 43. Nevertheless, there could be situations when more than one of network's buses will function healthier though rest function poor and in such situations, the overall VQ performance of distinct buses can be accurately benchmarked via Equation (15) though the precision of the decision taken, about the overall VQ performance, will drop with an increase in the count of buses in the DN.…”

“…The practical importance of the proposed approach is validated by applying it over each bus of an IEEE 13‐bus test distribution system modified by nonlinear loads and power quality disturbances as well as simulated in MATLAB/Simulink. The typical IEEE 13‐bus test system is fundamentally a 5 MVA, 60 Hz, various voltage levels of 0.48 kV and 4.16 kV, feeding balanced along with unbalanced linear loads 43 . The base voltage of 11 kV and base MVA of 10 MVA is used for transforming all the quantities into their respective per unit.…”

Summary The quality of voltage is a fundamental characteristic that forms a crucial part of reliability in smart distribution power grids and subsequently being cautious to that is obligatory. Voltage quality (VQ) issues can be categorized into manifold categories such as voltage fluctuation, voltage harmonic distortion, voltage unbalance etc, depending upon the type of deviation from the standard sinusoidal one in terms of magnitude and frequency. For evaluating the VQ at a distribution system's bus, classically all the crucial phenomena associated indices are obligatory to be discretely measured and benchmarked for guaranteeing the global healthy VQ performance, which makes the assessment of the same a quite cumbersome. This paper attempts to streamline the overall VQ evaluation process by the application of multiple criteria decision‐making. The scores of all VQ phenomena are computed by applying the analytic hierarchy process considering the multiple criteria of impacts on the consumer. The steps of the proposed methodology result in the formulation of an overall VQ index, which is alone adequate for raking the VQ performance of all the buses in a distribution power network. The proposed approach's application importance is checked and validated using data collected from a modified IEEE 13‐bus test distribution system with and without the inclusion of distributed generation systems using MATLAB programming.

“…Conceptually the PCC bears background unbalance because of loads connected at other buses. Therefore, case-3 gives challenges for SAPF to compensation harmonics under a large distribution instead of an Figure 12(a) [41] shows the MATLAB/Simulink based model of modified IEEE 13 bus test distribution network with 3-phase chopper fed DC motor industrial drive and SAPF installed for compensation purpose while complete schematic of Lyapunov function based SAPF is depicted in figure 12(b). The parameters used in the simulation are specified by table IV.…”

Shunt active power filter (SAPF) belongs to the class of custom power devices (CPDs) and offers compensation to harmonics originated owing to customer side nonlinear loads, reactive power and unbalance in the distribution power networks functioning in current control mode (CCM). The performance of a SAPF as a harmonic compensator entirely relies on the control technique i.e. the precise detection of the harmonic current components of load that are necessary to be compensated. In the present work, a 3-phase SAPF, inspired by a Lyapunov function based control approach, has been designed for compensation of harmonics resulted in the feeder current owing to the customer side nonlinearity. A control law is determined in the proposed strategy which makes the derivative of the Lyapunov function consistently a negative one for an entire set of stable states. The DC-link capacitor voltage is regulated at constant reference through the proportional-integral (PI) controller. In this method rating of the shunt active power filter is considerably reduced than the other two broadly employed conventional methods. Furthermore, the harmonic compensation efficacy of the proposed Lyapunov function based SAPF is compared with the one based on other two conventional approaches under four different system scenarios namely a simple nonlinear load with and without utility side voltage distortion, a modified IEEE 13 bus test distribution system loaded with a 3phase chopper fed direct current (DC) motor drive at a single bus and last especially for increasing the harmonic-constrained penetration level of renewable energy. Results obtained through simulation performed in MATLAB/Simulink shows that total harmonic distortion (THD) of source current and dynamic, as well as steady-state performance with Lyapunov function based controller, is significantly improved than the other two conventional methods. Also, the robust compensation performance of the SAPF empowers it to deal with the high penetration of renewable energy.

The power quality assessment provides a reference for power quality management and control of microgrid operation. In terms of reflecting the correlation of power quality indexes and the dynamic changes of microgrid operating conditions, the traditional power quality assessment methods need to be improved. A power quality comprehensive evaluation based on CRITIC and dynamic coefficient is proposed in this paper. In this method, the objective weight of power quality indicators in single node is determined by using the intensity of conflict and contrast firstly. For the node weight calculation, the dynamic coefficient is proposed to reflect the different influence degree of node with different connected load. The proposed method in this paper can reflect both the internal characteristic of data sequence and the relationship between different data sequences. In addition, it also can reflect the dynamic changes of microgrid. Finally, an example is used to verify the feasibility of the proposed method.
