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.

Dr Ashish Agalgaonkar
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 …

Secure And Practical Key Distribution For Rfid-Enabled Supply Chains, Tieyan Li, Yingjiu Li, Guilin Wang
Dr Guilin Wang
In this paper, we present a fine-grained view of an RFIDenabled supply chain and tackle the secure key distribution problem on a peer-to-peer base, In our model, we focus on any pair of consecutive parties along a supply chain, who agreed on a transaction and based on which, certain RFID-tagged goods are to be transferred by a third party from one party to the other as in common supply chain practice. Under a strong adversary model, we identify and define the security requirements with those parties during the delivery process. To meet the security goal, we first propose a resilient …
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 …

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 …

The Probability Distribution Of Distance Tss-Tls Is Organism Characteristic And Can Be Used For Promoter Prediction, Yun Dai, Ren Zhang, Yan-Xia Lin
Associate Professor Yan-Xia Lin
Transcription is a complicated process which involves the interactions of promoter cis-elements with multiple trans-protein factors. The specific interactions rely not only on the specific sequence recognition between the cis- and trans-factors but also on certain spatial arrangement of the factors in a complex. The relative positioning of involved cis-elements provides the framework for such a spatial arrangement. The distance distribution between gene transcription and translation start sites (TSS-TLS) is the subject of the present study to test an assumption that over evolution, the TSS-TLS distance becomes a distinct character for a given organism. Four representative organisms (Escherichia cloi, Saccharomyces …
