“…This paper extends the analytical formulation proposed by the authors in [15] to devise a volt/var control method that regulates the voltage level across a combined MV-LV network while reducing voltage unbalance. While the proposed control in [15] has remained within a unity power factor operation of PV inverters, non-unity power factor operation of PV inverters not bounded by AS 4777.2 will mainly be considered in this paper. Active participation of PV inverters in voltage regulation will also be taken into account with the presumption that the inverters are capable of operating at full range of power factor conditions.…”

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 regulation methods in LV networks used to be isolated from the associated MV networks, with the assumption that the MV networks are not affected by the control methods [15]. However, voltage issues as well as voltage control actions on one side of the distribution network might have significant effects on the other.…”

“…These changes have become beneficial to the power system, contributing to the development of active distribution networks and taking research in new directions regarding the control and optimization of these systems so this power can be exploited in the best possible way. This is a highly complex problem, especially when controlling the voltage and challenging the traditional control of the same [24,25].…”

“…To solve the problem of controlling voltage stability with the high incidence of renewable energy as a generative source, and as power systems adapt their capacities to accept these sources, various research works have contemplated Volt-VAR control, which has been a great discovery in recent years [26]. Voltage regulation is traditionally performed only on the medium voltage (MV) side of the power grid; most distributed generation systems are installed on low voltage grids, which makes a priority front of the unidirectional power flow in power grids responsible for distribution [24].…”

“…Thus, the research/simulation should present detailed network in order to simulate network performance. Nevertheless, the medium voltage (MV) network is often represented by active and reactive power [6][7][8] to simplify the network due to large and complexity of upstream network. Plus, most of the customers' loads are connected within the downstream of MV network.…”

Urban and rural medium voltage networks reliability assessment

et al. 2020

View full text Add to dashboard Cite

Distribution network operators typically produce a report of network performance for all networks as a whole, by not segregating it in a different area; urban and rural networks. Although the report is sufficient, it does not represent the actual performance of each urban and rural networks. Therefore, this paper presents the configurations, parameters, and component rating for medium voltage urban and rural distribution networks. Both networks are assessed with analytical and Monte-Carlo simulation techniques. Each assessment was correlated with Energy Regulator requirements for accurate results. Urban area has better network performance due to sophisticated network automation and network configuration with n-1 or n-2 security compared to the rural area.
