On the procurement side, retailer faces uncertainty of pool electricity price and at sell side, it sets selling price based on the elasticity of its consumer demand. The work contributes by highlighting the impact of demand behavior on a retailer's decision making for different price elasticity and providing informed decision support under pool price uncertainty to address different risk-averse nature of retailers.","PeriodicalId":286358,"journal":{"name":"2017 6th International Conference on Computer Applications In Electrical Engineering-Recent Advances (CERA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115737681","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 context, it is interesting to investigate the impact of network reconfiguration (NR) on further enhancement of these vital objectives for efficient system operation. This paper addresses a thorough investigation of NR for reliability and performance improvement in modern distribution systems considering the presence of shunt capacitors (SCs) and distributed generators (DGs). The complex combinatorial NR problem is solved using a recently developed chemical reaction optimization (CRO) algorithm that efficiently deals with the stringent radiality constraint. The investigations are carried out on benchmark IEEE 33-bus test distribution system and results of the analysis are presented explicitly.","PeriodicalId":286358,"journal":{"name":"2017 6th International Conference on Computer Applications In Electrical Engineering-Recent Advances (CERA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128276164","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 functions of robust control algorithm are load balancing, reactive power compensation, power factor correction with active power generation for proposed topology. The perturb and observe algorithm is used to extract maximum power from PV array under variable insolation levels. To adapt with variation in terminal voltage at point of common contact (PCC), PV feed forward term is also added in control algorithm to make less oscillations in grid current. The advantages of control algorithm are robustness, less complex, amplitude and frequency adaptive nature. Test results demonstrate satisfactory response for steady state and dynamic conditions at load unbalancing and variations in insolation level. The distortion in grid currents and voltages are found within limits IEEE-519 standard.","PeriodicalId":286358,"journal":{"name":"2017 6th International Conference on Computer Applications In Electrical Engineering-Recent Advances (CERA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124966473","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}

Degree of Polymerization (DP) value is perhaps the most effective parameter for determining the remaining life of an Oil-Impregnated-Paper insulation system. Due to the invasive nature of the test, DP value determination using paper samples is not practically feasible for in-situ transformers. On the other hand, commercial equipment's make it relatively easy to obtain the values of paper-moisture and tanδ. Hence, these parameters have become popular among utilities. In the present paper, paper-moisture and tanδ are used to obtain several important dielectric properties (like tensile strength, Degree of Polymerization, hotspot temperature) which are subsequently used for estimating the remaining life of several real-life power transformers. Efforts are also made to identify the method which is capable of identifying remaining life of power transformer with minimum error.","PeriodicalId":286358,"journal":{"name":"2017 6th International Conference on Computer Applications In Electrical Engineering-Recent Advances (CERA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124293810","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 voice signal is converted into an electrical signal using a microphone and this analog signal will be converted into a digital signal using appropriate quantization level and sampling rate. This digital data is then transmitted over the WLAN network using internet protocol in certain defined packet size, i.e. 8 bit digital packet. At the receiver's end, packets passed through WLAN are received as is, which are combined and converted back to the transmitted analog signal from transmitter's end. These signals can be combined into sound signal through a speaker connected with receiving computer. This method of communication over internet protocol is generally called VoIP, i.e. Voice over Internet Protocol. This method can replace the current PBX telephonic network inside organizations. The demonstration of this mode of communication has been successfully done on institute WLAN with the VoIP server.","PeriodicalId":286358,"journal":{"name":"2017 6th International Conference on Computer Applications In Electrical Engineering-Recent Advances (CERA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131588520","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}

Zero-voltage switching (ZVS) of the inverter switches for wide variations in input voltage and load is achieved by designing the converter to operate in above resonance mode. Steady state approximate AC circuit analysis method is used to analyze the converter with fixed-frequency phase shift control. LCL-T converter offers a built-in protection against short-circuiting of the load. LCL-T converter with fixed-frequency control requires a very small change in phase shift to regulate the output voltage for wide variations in input voltage and load. Due to ZVS for the entire input voltage and load variations, the operating efficiency of the converter is high. A 300 W, DC-DC, LCL-T resonant converter is designed for solar energy generation applications. The performance of the converter with the proposed fixed-frequency phase shift control is studied with PSIM simulations. The theoretical and simulation results are compared and presented.","PeriodicalId":286358,"journal":{"name":"2017 6th International Conference on Computer Applications In Electrical Engineering-Recent Advances (CERA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127812514","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 SVPWM the quality of the inverter output waveform mainly depends upon the applied switching sequence.
