Nevertheless, a large network of Fast Charging Stations (FCSs) is essential to enable the PEVs to be competitive with traditional vehicles for long distances. FCS creates heavy loading on the distribution system owing to the high power requirement for simultaneously charging various PEVs. This significant loading results in heavy stress on the system, which could negatively impact the grid performance. An electric energy storage system integration inside the FCS could mitigate these impacts. In this paper, an investigation of the impacts of FCSs on the distribution system has been performed. Furthermore, an analytical approach for coordination of charging/ discharging of stationary batteries (SB: a unit containing some batteries is used as an energy storage system) with FCS is developed. Which addresses technical issues such as peak demand, voltage profile deviation, and power loss in the system. The stationary batteries are used in two modes grid to the battery (G2B) and battery to the vehicle (B2V) for optimal coordination of SB with FCS. The simulations are carried out on the IEEE-33 bus distribution system.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115749681","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 proposed ENDO estimates the unknown lumped plant uncertainties, including exogenous plant disturbance and parametric uncertainty. Subsequently, a refined sliding mode control action is formulated by augmenting this estimation for effective damping of frequency oscillations of hyPS. An updated sliding manifold is introduced to accelerate state convergence rate and ensure finite time convergence. The boundedness of disturbance estimation error and closed-loop stability with an ENDO-aided frequency controller has been guaranteed considering the Lyapunov theorem. The efficacy of the developed control system has been shown over other well-known controllers reported in the literature under diverse operating conditions. Analysis of the system performances demonstrates the supremacy of the developed resilient control methodology in terms of fast damping of system oscillations, least chattering in control input, and robustness.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129627315","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 performance of wide area damping control (WADC) heavily relies on cyber and physical infrastructure. As the measured input signals used in WADC are transferred to the controller location via a communication channel, it is prone to cyber-attacks. The attacker can inject malicious data into the WADC measurements and/or control signals. This paper focuses on modeling and analyzing the impact of different types of false data injection (FDI) attacks on the WADC control signals, namely, sinusoidal attack, triangular attack, saw-tooth attack, ramp attack, pulse attack, random attack, and replay attack. The control architecture for analyzing these attacks consists of power system stabilizers placed on each generator for damping of local modes and an $H_{2}/ H_{infty} $ based WADC controller for damping of inter-area modes in Kundur’s 4-machine 2-area test system. Different types of attacks were compared for their severity, and it has been found that a sinusoidal attack has the highest severity of all the analyzed FDI attacks. The results obtained in this paper will be useful in implementing the cyber-attack detection and mitigation algorithms.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127442999","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}

As a result, fault analysis in PV arrays has evolved into a crucial task for protecting PV modules from damage and minimizing the possibility of occupational hazards. However, PV systems are covered by standard protection mechanisms, although some faults with low mismatch and high fault impedance levels may go undetectable. It might be challenging to discern an anomaly from normal operation due to the often-minute changes in electrical signal magnitude caused by malfunctioning photovoltaic components during such faults. In such cases, data-driven machine learning methods give reliable detection and classification results. This paper presents a workflow to use a machine-learning library of a distributed computing framework, PySpark. PySpark, a Python API for Apache Spark, is a powerful computational engine that efficiently handles enormous data volumes. The key characteristics of I-V curves under various fault occurrences and standard conditions are extracted from a MATLAB simulation of the PV Module for fault detection on the dc side of the PV array. The ML library in PySpark is then used to examine these attributes and detect faults. A confusion matrix addressing soft accuracy, precision, recall, etc., is used in a comparative analysis of several classification methods.","PeriodicalId":162808,"journal":{"name":"2022 22nd National Power Systems Conference (NPSC)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126304246","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}
