In this paper a non-linear gain sixth-order boost point of load converter is proposed. It is sixth-order topology, where its gain characteristic is contributed by a non-linear numerator term while denominator preserves the quadratic dependence. To examine the proposed converter performance, a detailed time-domain and steady-state analysis is presented. The L, C components expressions, along with steady-state operating point, are formulated in terms of ripple quantities. The state-space models are derived, for continuous inductor current-mode of operation, and then small-signal analysis is performed to identify the nature of the proposed converter during dynamics. Later on these transfer functions are used in the digital controller design. The proposed circuit is able to boost the load voltage to a higher value than the traditional quadratic boost converter reported in literature. A 48 V, 50 Watt prototype point of load converter with 12 V dc-battery as input is built to supply the power at constant load voltage. The proposed converter features are demonstrated both in simulations and experimentation.

This paper presents a method of reducing data communication burden in multi area load frequency control. An aperiodic event-triggered based control approach has been adopted to reduce the communication bandwidth requirements and governor operations. The control law is computed and actuated only when a pre-defined output dependent event condition is satisfied. The triggering condition in the previously reported works, depends on system states or outputs of all areas which is generally not available in an area control center of a real power system. Therefore a distributed event-triggered load frequency control has been proposed where the triggering condition in an area control center depends on output information of that particular area. A passivity based approach is adopted to ensure the system stability analytically and to derive the event triggering condition. Performance of the proposed controller was shown in terms of RMS error of frequency, tie line deviations and the reduction in communication burden for continuous load change, step load change and plant model variations in a two area test system.

This paper presents a robust least mean mixed norm (RLMMN) adaptive control scheme for multi-objective grid integrated solar photovoltaic (GPV) system under abnormal grid conditions. The control scheme serves manifold objectives such as load balancing, harmonics elimination, improving active power penetration into the distribution network while having active shunt filtering capabilities. The estimated perturb and observe (EPO) scheme is used to harvest crest power from solar photovoltaic (PV) array under variable atmospheric conditions. The proposed control scheme is robust under impulsive power system environments and has the advantages of low steady-state oscillations, low complexity, less mean square error and good dynamic response. The comparative performance with the conventional algorithms depict the satisfactory performance under dynamic condition. The DC link voltage is adapted in proportion with PCC voltage to reduce VSC (Voltage Source Converter) converter losses and its tripping under weak distributed grid conditions. Test results demonstrate the satisfactory behavior under steady-state and dynamic conditions of load unbalancing, variable solar insolation and grid voltage fluctuations. The total harmonic distortions (THDs) of grid currents are observed within limits of grid codes compliance according to an IEEE 519 standard.

Stability in voltage profile is the core issue in developing and operating electrical power systems and it's violation is reported to be the cause of blackouts all over the word. Voltage collapse can be prevented by providing reactive power support via generators power scheduling, tap changing transformer, reactive power compensating devices, capacitor banks, FACTS devices. Subsequently, the last line of defense for voltage recovery is load shedding. This paper proposes a method to optimize the shedding of load mandatory to revive the stability of point of operation while justifying the operating constraints. Optimal load shedding is done after identification of critical load buses. The approach anticipates the risk of voltage instability in the system using L-index. Black Hole Algorithm (BHA) is employed for efficient optimization of load shedding against voltage collapse. Further, results have been analogized with Bare Bones PSO (BBPSO). The computation is carried on IEEE-14 bus system.

This paper focuses on the simultaneous frequency and voltage control of an isolated hybrid wind-diesel power system using Superconducting magnetic energy storage (SMES) system and static Var compensator(SVC). Since inertia of the system is small, any disturbance in load will cause electromechanical oscillations which degrades the power quality(both voltage and frequency) of the system. Center of inertia technique (COI) is used to estimate the system frequency which is used for controlling SMES unit. SMES unit is used to modulate the active power using an adaptive predictive control scheme which generates reference power for the SMES and forces it to follow the power command. Reactive power control is achieved by SVC. Both SMES and SVC are modelled as controlled current sources and act as sources/sinks of active and reactive power respectively. Simulation results show that the deviations in voltage and frequency are reduced considerably by incorporation of SMES and SVC at a specified bus in the system.

Battery being an important prospect for energy storage for various applications, we need to use it economically taking battery health into consideration. Taking it in the context of wind farm power generation and management, whenever the forecasting power estimates are higher than the actual wind power, the deficit is supplied through the batteries. In the case of higher actual wind power than the forecasted power, we charge the batteries. This paper focuses on how we should charge and discharge the batteries so that we can decrease the number of storage elements required without harming their effective life. An economic study is presented on how to opt for a suitable methodology to balance the penalty with preferred wind forecasting schemes.

This paper presents an application of fuzzy logic theory for aerodynamic modeling of the fixed wing aircraft. For the demonstration purpose, rolling moment control and stability derivatives of ATAS aircraft are extracted from the recorded flight data of nonlinear flight profile. Fuzzy logic based Takagi Sugeno Kang (TSK) model is used to represent the nonlinear dynamics of the aircraft, which can approximate it into several locally linear models. The method shows its benefit in case when it becomes very difficult to identify the equilibrium points (trim points) due to cross coupling and nonlinear complexities associated with modern aircraft. The grid based Rusipini type fuzzy partitions are used for input spaces and two triangular type membership functions are generated per input from the training data set. The fuzzy rules are extracted based on weighted least square algorithms and each rule corresponds to local linear model for mimicking of aerodynamic (control and stability) derivatives. Fivefold cross validation method is used to access the adequacy of the generated fuzzy model. The parameter tracking trends and mean square error for training and testing data sets show commendable modeling capability of TSK fuzzy model for extraction of aerodynamic derivatives.
本文介绍了模糊逻辑理论在固定翼飞机气动建模中的应用。为了演示，从记录的非线性飞行廓线飞行数据中提取ATAS飞机的滚转力矩控制和稳定性导数。采用基于模糊逻辑的Takagi Sugeno Kang (TSK)模型来表示飞机的非线性动力学，将其近似为若干局部线性模型。在现代飞机由于交叉耦合和非线性复杂性而难以确定平衡点(纵倾点)的情况下，该方法显示出其优点。输入空间采用基于网格的Rusipini型模糊划分，每个训练数据集的输入生成两个三角型隶属函数。基于加权最小二乘算法提取模糊规则，每个规则对应一个局部线性模型，用于模拟气动(控制和稳定)导数。采用五重交叉验证法对生成的模糊模型进行充分性检验。训练和测试数据集的参数跟踪趋势和均方误差表明，TSK模糊模型在提取气动导数方面具有良好的建模能力。

This paper presents an islanding detection technique using superimposed positive sequence voltage and current for microgrid system. The conventional passive methods have the drawback of non-detection zone (NDZ), and active islanding detection methods introduce disturbance which might cause problems with reliability, stability, and power quality on a power system. Two systems are simulated using RSCAD/RTDS software and several test cases are generated to test the performance of the proposed technique.

Presence of partial discharges is a serious issue in the maintenance and condition monitoring of power cables. Under the effect of excess electrical field, the voids present in the insulation may go through breakdown, giving rise to the phenomenon of partial discharges. Repeated occurrence of partial discharges through a long period of time may lead to complete insulation failure. The partial discharge activity is dependent on the applied voltage, shape, size and location of voids and presence of minor protrusions on the conductor surface. In this study, the effect of all these factors was studied using a simulation model based on Finite Element Analysis (FEA) software. Three different void geometries were considered and their effect on partial discharge inception voltage, both in the presence and absence of protrusions, was studied. The location of the voids was also varied in the simulation study. From this work, an improved understanding of partial discharge within power cable insulation as well as its relationship with void geometry and location can be obtained.
