The modelling examined the least and near least cost technology portfolios for a scenario that limited emissions to approximately one quarter of those from the Australian National Electricity Market (NEM) at present. It was found that all the near least cost solutions (within 15% of the least cost solution) involved wind capacity in the range of 31-51 GW, with 98.8% of these near least cost portfolios having at least 35 GW of wind installed. In contrast, the near least cost solutions consistently involved much lower quantities of PV, with 90% of the near least cost portfolios having less than 4.9 GW of installed PV capacity. This suggests that policies to promote high levels of wind deployment and grid integration are likely to be important for achieving low cost, low emissions outcomes, while policies to promote significant PV deployment may be less warranted in the absence of cost effective supporting technologies, such as battery storage or significant demand side participation.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121368474","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}

The results show that the proposed tool based on DSM information by using GIS can precisely determine the amount of solar radiation considering the solar orbit under the condition of no clouds, and evaluate an optimum location for PV installation.

In this paper, a steady state control strategy that can be used in a meshed HVDC grids is presented. The control strategy combines local primary controllers and a central secondary or supervisory controller. The objective of the primary controllers is to enable shared management of required changes in bus powers as a result of a disturbance in the system. The objective of the secondary controller is to change voltage and power settings of the primary controllers so that power flows in the transmission cables of the system are kept within the thermal limits after the disturbance. The primary controllers react first when there are disturbances in the system followed by the secondary controller which acts only when necessary.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"328 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115873985","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}

Hybrid energy storage system (HESS), which combines various ESs, can optimize energy density, power density and dynamic response. Hierarchical control of HESS is shown able to achieve dynamic power sharing among ESs with improved system reliability. However, system stability of HESS under hierarchical control, which is essential for parameter design and system operation, has not been investigated. In addition, with high penetration of constant power loads (CPLs) in DC distribution system, impact of CPL on system stability should be studied. This paper investigates stability problem in HESS with CPL under hierarchical control. A detailed small signal model for stability analysis is developed. Impacts of CPL and system parameters are analyzed. Effectiveness of the control strategy and analytical results are validated by time domain simulations.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"50 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133075871","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}

In this paper, the vibration sensors based on piezoelectric effect are attached to the oil tank of transformer to acquire the vibration signals in short circuit condition, and then the transfer function is applied to study the relationship between the vibration and short- circuit current under multiple short circuit shocks. Compared with traditional frequency domain or time- frequency domain analysis, this method can normalize the vibration in different short circuit condition and clearly illustrate the relationship between vibration and current. The conclusion shows that this method is feasible to evaluate the mechanical condition of transformer by using the correlation analysis of amplitude- frequency characteristic of transfer function in different short circuit condition.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132163914","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}

Time series estimates of distributed PV generation mapped to different Australian geographic regions are now being created from a sample of these distributed PV systems that report their generation in near real time. In this paper a range of potential applications of these spatial PV generation traces are discussed, with a focus on their potential contribution towards transmission network planning and operations.

It is mainly used to solve the power quality (PQ) problems of low power factor (PF) and three-phase unbalance. However, it pollutes the power system by producing harmonic currents during normal operation. This paper proposed a multi-objective optimal control strategy to improve the comprehensive PQ. Firstly, the total harmonic distortions (THD) of the three-phase currents are pre-estimated. Then the relations between the trigger angles and the PQ indices are deduced. The objective function is established based on the scoring function and the weights of the PQ indices. Finally, quasi-newton method is used to find the optimal trigger angles. This method improves the PQ without additional equipments. Simulation results of case studies show that the proposed control method is effective and feasible.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114483133","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}

Some uncertain factors are taken into account such as coal price, the electricity price, coal consumption, fill rates of contracted coal and coal purchased from the coal market.

But for active distribution grid, this traditional voltage regulation scheme may fail. Therefore, a novel coordinated voltage control strategy is proposed to regulate voltage of distribution network with the integration of DGs. Both OLTC and DGs are considered as voltage regulators. The voltage control zones (VCZs) of OLTC and DGs are determined initially and the hierarchical voltage regulation method is adopted in each VCZ to eliminate the overlimit voltage. Simulations carried out on the IEEE 33-bus radial distribution network demonstrate that the proposed strategy can regulate voltage more efficiently, increasing energy efficiency and reducing the number of multiple regulating devices action.","PeriodicalId":439089,"journal":{"name":"2015 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"76 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116289636","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}
