For accurate monitoring of its drinking quality water, low-cost measuring system is required. In this work we propose one such solar PV based system utilizing Wireless Sensor Networks (WSN) technology for accurate water quality monitoring. Three sensors: (a) pH Sensor (SKU: SEN0169), (b) Turbidity sensor (SKU: SEN0189) and (c) Temperature sensor (DS18B20) are employed in the system hardware. These sensors are connected with Arduino, Global System for Mobile (GSM), and liquid crystal display (LCD) for the purpose of communication and monitoring respectively. These sensors measure the required parameters (pH, turbidity, and temperature) and forward it to Arduino which are then displayed on the LCD. The measured values are transmitted through the GSM for monitoring purposes. A solar panel is used power-up the system and autonomy is provided through a lead-acid battery This allows application of system in remote areas where grid is unavailable. The system can also have other applications in the agriculture systems, aquaculture systems, domestic systems and in small industrial setups.","PeriodicalId":314530,"journal":{"name":"2018 Australasian Universities Power Engineering Conference (AUPEC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122156273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These renewable based distributed generations provide an alternative clean source of power and allow a significant portion of the load to be supplied locally, reducing the power consumed from the grid. However, in terms of distribution system operation they can cause unexpected adverse effects such as reverse power flow, voltage rise and voltage unbalance. Furthermore, the amount of rooftop solar PVs injected is expected to increase significantly. This makes it essential to reassess the distribution network performance which was originally designed for downstream power flow. This paper presents a three-phase power flow approach based on the current mismatch variant of the Newton Raphson to assess the effect of high penetration of single phase PV units and how energy storage systems can help to mitigate the undesired effect. The paper presents a comprehensive three-phase detailed modeling of the key components in the grid suitable for use with the three-phase power flow algorithm. The strategy to utilize the energy storage devices, to mitigate the issues of rooftop PVs has also been proposed. The results from a 24-hour simulation using data from an actual distribution network in NSW, Australia have validated the proposed models, demonstrated the undesired impacts of the integration of a high penetration of single phase PV units in the distribution grid, and demonstrated the role of storage devices to mitigate the undesired impacts.","PeriodicalId":314530,"journal":{"name":"2018 Australasian Universities Power Engineering Conference (AUPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129805221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents current and voltage harmonic issues of distribution networks in the frequency range of 0–9 kHz. These harmonics could affect communication and control signals in smart meters, Power Line Carrier (PLC), and ripple control signals. Power electronics systems based on Active Front End (AFE) topologies are utilized in many applications such as solar inverters. It is important to evaluate the impact of grid connected power electronics converters on harmonic emissions especially above 2 kHz in distribution networks.

Thus, this paper proposes an LVRT strategy and compares its performance with a widely used conventional LVRT strategy. The proposed strategy is designed with a capacitor connected in series with an inductor and both are connected in parallel to a resistor. This configuration is then connected to the ac side of the rotor side converter (RSC) via an R-L circuit. To validate the performance of the proposed scheme, three phase fault condition is simulated and analysed. Based on simulation results obtained in MATLAB/Simulink, there is significant improvement achieved in the stated objectives compared to the conventional LVRT scheme.","PeriodicalId":314530,"journal":{"name":"2018 Australasian Universities Power Engineering Conference (AUPEC)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127676562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A power sharing scheme is designed to give PV sources the priority of power supply. Based on the scheme, adjusted droop control strategy is employed for voltage source inverters (VSI). Considering PV power characteristics, a DC/DC converter controller is also designed for PV panels. There are two operating modes of PV sources: maximum power point tracking (MPPT) mode and power curtailment (PC) mode. MPPT mode is supported by MPPT technique combining with a frequency increment on the VSI droop controller. The traditional droop controller and DC bus voltage tracking loop support PC mode. Stability analysis is conducted. Simulation results show the control strategy can share power demand effectively among different kinds of power sources even under varying weather conditions.","PeriodicalId":314530,"journal":{"name":"2018 Australasian Universities Power Engineering Conference (AUPEC)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121932682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This trend will continue growing because of fast improvements of both computational resources and robust optimization techniques. Relevant problems associated with the voltage magnitude and reactive power may be difficult to represent in the transmission planning problem if the DC mathematical formulation is used instead of the AC formulation. However, the AC formulation remains difficult to solve even with the nowadays solution methodologies. Therefore, the development of new methods that allows to solve effectively the AC formulation are highly relevant. In this paper, novel heuristic methods to solve the transmission planning problem are proposed. The results show that the proposed heuristics for the AC transmission planning problem are both effective and efficient to solve the problem. Moreover, it has been determined the most suitable heuristic criteria for the proposed heuristics.
