However, with the introduction of advanced features, such as remote control, potential cyber security threats in SASs are also increased. Additionally, crucial components in SASs, such as protection relays, usually come from third-party vendors and may not be fully trusted. Untrusted devices may stealthily perform harmful or unauthorised behaviours which could compromise or damage SASs, and therefore, bring adverse impacts to the primary plant. Thus, it is necessary to detect abnormal behaviours from an untrusted device before it brings about catastrophic impacts. Anomaly detection techniques are suitable to detect anomalies in SASs as they only bring minimal side-effects to normal system operations. Many researchers have developed various machine learning algorithms and mathematical models to improve the accuracy of anomaly detection. However, without prudent feature selection, it is difficult to achieve high accuracy when detecting attacks launched from internal trusted networks, especially for stealthy message modification attacks which only modify message payloads slightly and imitate patterns of benign behaviours. Therefore, this paper presents choices of features which improve the accuracy of anomaly detection within SASs, especially for detecting “stealthy” attacks. By including two additional features, Boolean control data from message payloads and physical values from sensors, our method improved the accuracy of anomaly detection by decreasing the false-negative rate from 25% to 5% approximately.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130782319","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 very first and utmost requirement for a resident is to know the base rate, above which the energy could be sold for getting profit. To calculate the base rate, the present work develops the levelized cost of electricity (LCOE) of 5kWp rooftop solar system by considering all the design factors including geographical location and other costs related to installation, operation & maintenance. As the geographical parameters effecting solar generation changes with location, the P2P minimum energy cost also varies. In order to study the effect of different locations, a simulation is carried out in system advisory model (SAM) software for 25 districts of Telangana state. With changes in unit rate, the model determines the base price to choose a tariff for residents to sell their solar energy in a P2P energy market. A case study of P2P energy transaction for 35 homes in a gated community is made and profit is calculated for PV and non-PV investors. This study calculates minimum price of selling solar units and it's respective profits which motivate investors and non-investors to engage in P2P energy trading. It also helps the policymakers to derive new policy required for P2P energy trading and for distribution companies to fix unit rate of feed-in-tariff (FIT).","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129201261","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}

Firstly, the topological structure and working principle of resistive superconducting fault current limiter and coupling mechanical DC circuit breaker are analyzed. Secondly, the principle of superconducting fault current limiter and coupling mechanical DC circuit breaker coordination is analyzed, and on this basis, the coordination timing sequence of superconducting fault current limiter and coupling mechanical DC circuit breaker is proposed.

In grid connected mode PV source connected inverter is operated as controlled current source using P-Q control method. In islanding mode main control objective is to control voltage and frequency within a nominal range for stable operation. V-f Control based droop control method is used in islanding mode by operating inverter as controlled voltage source. Also in PV based MG it is necessary to maintain DC bus voltage stability that occurs due to load change or grid disconnection. In islanding mode it is essential to maintain DC bus voltage stability to avoid overloading of PV source by accurate power balance. In this paper modified power management scheme is proposed so that PV source can work as controlled voltage source in grid connected mode as well as in islanding mode which is capable of maintaining dc bus voltage stability during load change or during grid disconnection. Using proposed method desire power transfer in grid connected mode and stable islanding operation as well as smooth transition between both modes are achieved. Simulations results are presented to validate the effectiveness of the control approach.","PeriodicalId":345537,"journal":{"name":"2021 13th IEEE PES Asia Pacific Power & Energy Engineering Conference (APPEEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122357359","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}
