In this article, Exogenous and Brownian white noise as stochastic perturbation along with uncertain load disturbance is considered. In practice, uneven and abnormal disturbance which are often unpredictable in single area power system is taken into consideration. The said design ensures finite time convergence of frequency and area control error under above said disturbances with chattering free control signal. Higher order sliding mode observer estimates all the system states which are difficult to measure or are unavailable. The frequency deviation is found to be within acceptable range under random load disturbance and matched uncertainty confirming robustness of the said design. Further, performance is also observed with power system nonlinearities like generation rate constraints and dead band. The stability of sliding surface is proved theoretically using classical Lyapunov theorem and validated using MATLAB R2013b.","PeriodicalId":385912,"journal":{"name":"2018 2nd International Conference on Power, Energy and Environment: Towards Smart Technology (ICEPE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115414286","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}

It is achieved by inserting in parallel a combination of 2nd order passive low pass filter with the proportional-integral-derivative controller. The addition of the proportional-integral-derivative controller changes the characteristics of the conventional phase-locked loop and consequently reduces the settling time of the system. The mathematical model of the proposed phase-locked loop is derived in s-domain to study various aspects such as stability, settling time, phase margin, bandwidth, damping factor and overshoot. The simulation of the proposed model is performed on MATLAB platform. The simulation result shows that settling time of the proposed model is in the range of 0.0194 ns to 0.133 ns and the phase margin is in the range of 37.7 degree to 76.7 degree with damping factor as 0.704.

Flexible AC Transmission System devices (FACTS) like Static Var Compensator (SVC) can enhance line stability, improve voltage profile and minimize both the power losses and emission. Thus, the allocation of FACTS devices in power system is of great importance. However, due to their high installation cost involved, it is important to place these devices optimally in a power system. In this paper, an iterative study is carried out in Mi-power software for IEEE 57 bus test system. The severity of the line has been detected using Fast Voltage Stability Index (FVSI) and thereafter SVC is placed on the identified critical buses separately to save computation time and search space. In addition to the technical aspect, other aspects i.e. economic and environmental issues are also considered in this paper while placing SVC at the optimal location.","PeriodicalId":385912,"journal":{"name":"2018 2nd International Conference on Power, Energy and Environment: Towards Smart Technology (ICEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129156732","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, numerical investigations on solar air heater with hemispherical vortex generator have been carried out. Commercially available ANSYS 18.0 is used to carry out the overall investigation. The complex turbulent flow equations are solved using standard k-ω model. Various geometrical configurations (pitch, P=8 to 12, eccentricity, e= 0.018 to 0.04) of vortex generator and operating parameters (Reynolds no, Re= 4000 to 20000) are considered for the investigations on solar air heater with aspect ratio of 12.

Low inertia power grid causes the system frequency to change too fast after the occurrence of a severe contingency or disturbance. To deal with such issue, inertia emulation technique is proposed using battery management system (BMS) for three area power systems under deregulated scenario. Here, the control areas of the system under investigation are interconnected using high voltage direct current (HVDC) and HVAC transmission links. The measurements of frequency signal used by BMS for inertia emulation are done using derivative control technique considering the effect of phase locked loop (PLL) dynamics. Four conventional GENCOs and four DISCOs are considered in our study with photovoltaic (PV) generator penetrated in first control area. It is found that the emulated inertia can significantly improve the dynamic responses of various parameters of the power system.","PeriodicalId":385912,"journal":{"name":"2018 2nd International Conference on Power, Energy and Environment: Towards Smart Technology (ICEPE)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126512588","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}

Mostly the mathematical modeling, controlling of their kinematics, dynamics, swimming mechanism are main areas of interest. An intelligent Aquatic Robot generally exhibits three major functions, viz. guidance, control, and navigation. This paper is a discussion about the gradual development of these Fish Robots and their swimming, propulsion, locomotion mechanisms etc. that involved. The main obj ective is to bring forward a conclusive, relevant and useful conclusion from existing literature so as to boost interest in the emerging area of these Fish Robots. The fish locomotion is one of the prime inspirations of Fish Robots, and most of the bio-inspired Fish Robots are designed by mimicking the fish swimming profiles. The fish swimming can broadly be classified as Body and/or Caudal Fin (BCF)movements or using Median and/or Paired fin (MPF)propulsion. The swimming profile and characteristics of mostly used propulsion mode of various Fish Robots are discussed here in this paper. It is known that robotic fish propulsion mechanism is very complex to realize in models, it involves several aspects such as shape of the robot, hydro-dynamics involved, pattern of movement, control system involved, mechanical properties, location of various mechanical components and properties of the material used etc. Various structures and materials used in existing Fish Robots and significance of selection are reviewed.
