However, in an event of unintentional islanding, injecting power into the grid may causes potential safety threats to people, equipment, and power system. This paper proposes an adaptive reactive power mismatch method to detect islanding events. When islanding occurs, the proposed method drifts the system frequency away from the nominal value. Then the islanding event is detected based on frequency variations. Results show that the proposed method effectively detects islanding event within 0.801 milliseconds and have negligible non-detection zone.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121304573","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}

An LBS can be automatically controlled by various signaling arrangements that are incorporated with a feeder remote terminal unit (FRTU), current transformer (CT), and voltage transformer (VT). Sometimes the metering CTs are used to detect fault currents. This can be saturated during a heavy fault. Thus, this paper proposed the simplified equivalent circuit to study the CT saturation in an LBS for a smart distribution system. The simulation was conducted by the DigSilent Power Factory and PSCAD simulation tools for verification of the proposed method. The results of the simulation software and experimental testing by using a current source transformer and on-site testing showed that there were slightly different secondary current values of these case studies. In this paper, the proposed analysis and experiment provided modeling and a measuring method of CT saturation testing in an LBS for a smart distribution system.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116345424","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 arrangement provides extra opportunity to earn revenue at high electricity tariff by discharging energy to the grid. The proposed configuration is equally capable of reactive power balance. A brushless DC (BLDC) motor is used for ancillary purpose and is powered by battery charger under grid outage condition.

The given approach entails the use of a direct formula for the formulation of modified ZN-PID controller, which obviates the need for the use of highly randomized soft computing algorithms, complex nonlinear control strategies and time consuming iterative approaches of controller design. The capability of the modified Ziegler Nichols rules is demonstrated via investigation of the transient and disturbance rejection performance of the solar tracking system.

Each loss minimization algorithm has its advantages and disadvantages. In order to achieve effective conclusion for search algorithm based loss minimization techniques (SABLMTs), a comparison between five optimization algorithms including the genetic algorithm (GA), particle swarm optimization (PSO), chaotic optimization algorithm (COA), simulated annealing (SA), and imperialist competitive algorithm (ICA) is presented. For this purpose, the induction motor and its loss model considering core loss in the d-q reference frame are used. The optimum magnetization current along with the linkage flux are determined in a way that the induction motor loss is minimized considering different loads. The performance of the online optimization-based vector-controlled IM is analyzed using MATLAB/Simulink software in which the online algorithms are implemented by Embedded Matlab Function block in the Simulink environment. The simulation results show that using the SABLMTs provides better efficiency for IM drives especially in light loads without imposing any undesired effects on the dynamic performance of the IM drives. At the end, to make a proper conclusion, different SABLMTs are compared in terms of the processing time and accuracy.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126811647","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 distribution level has historically been associated with the delivery of energy sourced from the transmission system via a wholesale electricity market. Due to the growth of embedded generation at the distribution level this flow is changing as solar and wind generation, electric vehicles, heat pumps and demand response activity via smart appliances and storage technologies develop. Therefore it is very important to integrate the retail market and distribution grid operations to optimize energy flows economically and achieve environmental targets. Therefore, at the distribution level, system modeling is required to qualify, quantify and value the installation of embedded energy storage. The aim of this paper is to establish a retail market framework to integrate embedded generation at the grid distribution level to avail of these untapped services.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123789712","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}

Therefore, this research analyses the impact of the GHI uncertainty on the economics of rooftop PV investments. This research used Semarang city as a case study. The uncertainty was modelled using the Monte Carlo simulation. The results show that the levelized cost of electricity (LCOE) is always below the tariff and above the generation cost. It implies that it is more profitable if it is built by the private sector (PLN’s customers) rather than build by PT. PLN itself.
