“…The simulation results are shown in Table 8. These results are compared with the RPO aiming at minimisation of active power loss [30], and the IVVC method and the control parameters of IVVC are pre‐set at Q Limit = 10 and Q Status = 2 [25]. Furthermore, simulation results are demonstrated in Fig.…”

“…In [24], a control coordination technique based on the concepts of control zone, line drop compensation, dead band, as well as the choice of controllers' parameters was proposed to minimise the interaction with other active devices. Afandi et al [25] proposed an integrated volt/VAr control (IVVC) to improve the overall voltage profile and reduce the total number of tap operations in middle‐voltage distribution networks. Reference [27] proposed a nine‐area control algorithm which is widely adopted as the local control method of the substation in China considering its simplicity and practicality [28].…”

“…References [16][17][18] for example, only elaborate strategies about regulating the voltage in the MV network while [5,19,20] aim at regulating the voltage in the LV network. While reported literature can successfully achieve the target voltage regulation, due to the separation between MV and LV networks, the proposed strategies are not sufficient in the constantly evolving active distribution networks.…”

The emergence of distributed generation such as solar systems has introduced new challenges in distribution networks that are becoming more apparent with increasing penetration levels. The time mismatch between peak load and peak generation can make voltage levels in distribution networks swing towards extreme limits during a day. Distribution network service providers are struggling to cater for new distributed generation installations while ensuring that the quality of steady state supply voltage meets stipulated requirements. The segregation between medium and low voltage networks in control strategies may result in unnecessary or worse, opposing control actions leading to voltage issues and control on one side of the distribution network influencing the other. By developing an efficient volt/var control method, the steady state voltage level and voltage unbalance in a comprehensive distribution network can be controlled simultaneously. This paper analyses voltage issues and volt/var control in medium and low voltage networks as a whole, unabridged problem. This paper proposes a pragmatic and effective volt/var control method that addresses voltage regulation and voltage unbalance simultaneously using existing infrastructure. The proposed control method is implemented on three types of representative Australian distribution networks and results obtained demonstrate that the proposed volt/var control can simultaneously manage voltage level and voltage unbalance whilst reducing the number of tap change operations and maximizing solar penetration.

Voltage Quality and Power Factor Improvement in Smart Grids Using Controlled DG Units

The increased penetration of renewable energy sources in the electrical grid, due to the rapid increase of power demand and the need of diverse energy sources, has made distributed generation (DG) units an essential part of the modern electrical grid. The integration of many DG units in smart grids requires control and coordination between them, and the grid to maximize the benefits of the DG units. Smart grids and modern electronic devices require high standards of power quality, especially voltage quality. In this paper, a new methodology is presented to improve the voltage quality and power factor in smart grids. This method depends on using voltage variation and admittance values as inputs of a controller that controls the reactive power generation in all DG units. The results show that the controller is efficient in improving the voltage quality and power factor. Real data from an electrical network have been used in the simulation model in MATLAB Simulink to test the new approach.
