Assessment Of Distributed Generation Impacts On Distribution Networks Using Unbalanced Three-Phase Power Flow Analysis, Md Jan-E- Alam, Kashem Muttaqi, Danny Sutanto
Assessment Of Distributed Generation Impacts On Distribution Networks Using Unbalanced Three-Phase Power Flow Analysis, Md Jan-E- Alam, Kashem Muttaqi, Danny Sutanto
Associate Professor Kashem Muttaqi
Impacts of Distributed Generation (DG) resources on distribution networks have been studied. A Newton-Raphson algorithm based three phase unbalance power flow program has been developed to incorporate the effects of system unbalance and single phase DG injection. Power flow equations have been formulated and solved in phase coordinated form. Effects of substation load-tap changer, voltage regulator, shunt capacitor and different type of load models have been considered in the development of the program. Phase asymmetry of distribution networks has been treated by modifying the Jacobian matrix. The proposed technique has been tested on IEEE 34 bus distribution test system for …

The application of renewable distributed generation (DG) could be considered as an alternative approach for distribution system expansion planning not only to reduce power loss and carbon emission, but also to improve system voltage profile. This paper investigates technical aspects relatedto voltage support and loss reduction in distribution systems with distributed wind and solar generation. The probabilistic wind, solar, and load models have been developed in order to address uncertain nature of wind speed, solar radiation, and load demand. Investigations have been carried out using Monte Carlo based probabilistic load flow analysis to estimate the probability distributions of system state …

The integration of Distributed Generation (DG) units and shunt capacitors can be considered as an alternative approach for distribution system expansion planning not only to improve power supply quality and reliability, but also to defer major system updates. In this paper, the techno-economic issues of distribution system expansion planning with optimal sizing and siting of DG units and shunt capacitors are addressed. The minimisation of overall investment cost with the integration of DG units and shunt capacitors is assessed with the consideration of supply quality, reliability and energy loss. A new planning methodology by using Particle Swarm Optimisation (PSO) is …
A Comprehensive Assessment Tool For Solar Pv Impacts On Low Voltage Three Phase Distribution Networks, M J E Alam, K Muttaqi, Danny Sutanto
A Comprehensive Assessment Tool For Solar Pv Impacts On Low Voltage Three Phase Distribution Networks, M J E Alam, K Muttaqi, Danny Sutanto
Associate Professor Kashem Muttaqi
Modern low voltage (LV) distribution networks are experiencing significant solar photovoltaic (PV) integration. Analysis of changing network behavior, resulting from daylong variation of feeder loads and PV outputs are becoming essential to capture the network response throughout the day under high PV penetration. A comprehensive tool has been presented in this paper to investigate the daylong changes in network behavior due to PV integration. The tool is capable of modeling the asymmetry and unbalance related complexities of distribution networks and also the effect of single phase PV on three phase distribution feeders. Analysis of PV impact has been performed using …

Integration of distributed generation (DG) in a distribution network may introduce adverse effects including control interaction, oscillatory transients and operational conflicts. This paper investigates the operation of multiple voltage regulators such as on-load tap changer (OLTC) and step voltage regulator (SVR), and DG in a medium voltage distribution feeder. Investigations have been carried out using time domain simulation studies conducted using MATLAB-SimPowerSystems. The results are reported for a case study involving radial distribution feeder, derived from New South Wales (NSW) electricity distribution network in Australia.
Optimal Allocation Of Renewable Enegy Resources For Minimising Emissions In The Distribution Network, M. Abdullah, A. Agalgaonkar, K. Muttaqi
Optimal Allocation Of Renewable Enegy Resources For Minimising Emissions In The Distribution Network, M. Abdullah, A. Agalgaonkar, K. Muttaqi
Associate Professor Kashem Muttaqi
Integration of renewable Distributed Generation (DG) into the distribution networks is one of the effective ways to ensure emission reduction with the added benefits of network support and transmission and distribution system expansion deferral. Emission reduction by renewable DGs mostly depends on the generation technology, size and type of DG units and curtailment of fossil fuel based grid energy. This paper proposes a strategy for evaluating the size and type of renewable DG and determining the best mix of different renewable DG technologies by minimising primary and operational emissions without violating network constraints. A methodology based on time sequential optimisation …
