The increase in demand for electricity and the growing energy density in the metropolitan areas have made it necessary to extend the high voltage network right up to the consumer. Gas insulated substations provide a best solution to the above problem and have been functioning for more than 30 years around the world. SF6 gas used in GIS has excellent dielectric properties, current interruption properties and also high heat transfer capacity. Considering the increasing population and increasing power demand across the globe, a complete study of the various problems in the GIS systems has to be completed so as to ensure an un-interrupted electric power supply to the customers and increasing the GIS applications. This paper brings to light the various special problems involved in GIS like Particle infusion in GIS, Insulating spacers and their reliability, SF6 gas decomposition in GIS, VFTs. The paper also discusses the significance of these problems, analysis based upon a graphical approach and the effect of these problems on the Indian power system.

Microgrid can effectively integrates micro-sources, loads and energy storage devices; can make economic and environmental benefits by using new energy power generation; can better meet the requirements of customers for higher power quality and reliability of power supply. The optimal operation of the microgrid is a complex optimization problem, which contains multi-goal and multiple constraint situations. In this paper, it takes the minimum economic cost and the smallest power loss of the microgrid as the objective function, considers a variety of constraints then builds a multi-objective function model for the optimal operation of microgrid. This article improves the chaos optimization algorithm and applies this algorithm to the optimization of microgrid. The simulation results verify that the proposed chaos optimization algorithman commendably achieve optimal operation of microgrid under multi-objective.

The appearance of microgrid solves the shortcomings of distributed generation and attracts the attention of the whole world. What's more, it has brought both opportunities and challenges for the development of electric vehicle charging stations. But due to the increasing use of electric vehicle chargers, the harmonic pollution of microgrid is becoming more and more serious, and it causes harm to both electric equipments and large power grid. Taking measures to govern the harmonic pollution is imperative, but before governance, the accurate and real-time detection of harmonic is indispensible. So this paper puts forward to use the improved HHT to detect the harmonics. The improved HHT combines the support vector regression machine and the mirror extension to improve the end effect of HHT and make the instantaneous frequency and amplitude become more meaningful. What's more, the improved HHT can accurately detect the starting and ending time of harmonic disturbances. Through the simulation results, it can be confirmed that this method is efficient and applicable for the harmonic detection in microgrid electric vehicle charging stations.

In this paper, an experiment involving a sudden generator disconnection in Faroe Islands power system is described. Three phase voltage and current signals were measured during the experiment. A novel parameter estimator based on Unscented Transformation (UT) and Kalman filter is implemented to estimate frequency and amplitude of the processed signals simultaneously. By avoiding the use of linearization procedures, UKF performs high estimation accuracy and lower computational demand compare to classical methods (i.e. FFT and EKF). This method has shown its immunity to high level of noise and is applicable for monitoring and protection purpose in power systems.

Development of microgrid is one of the solutions for keeping the power system intact to embed the distributed generations while considering renewable energies for substantial environment. This paper investigates the operation modes for the first outdoor microgrid test bed in Taiwan, whose generation capacity is 517.5-kW. The distributed generations in the microgrid system, which has 18 AC buses and 4 DC buses, include gas turbine, wind-turbine, PV and battery. The models of rectifier, booster and inverter are considered for both transient and dynamic simulations. The operation modes (power flow and voltage-frequency) are studied for both conditions of grid-tied and islanding operations. Preliminary simulation results reveal that proper operation modes for gas-turbine generations are crucial while other distributed generations are operated in the power mode.

Advanced metering infrastructure (AMI) security has become a challenging issue now days because of its integration with the external networks, remote system, and internet world. Today's metering infrastructure employs computer based monitoring and control operations to enable application of one network to exchange data with other application of different network. Communication protocol, network topologies, and computerization plays crucial roles to make the metering infrastructure advanced and further make a grid smarter. On the other hand, cyber attacks already associated with such computer networks and communication protocol can easily affect the communication of AMI applications. Therefore, from trespasser point of view, in this paper, we explore the various possible types of undesirable security threats followed by desirable security attributes required for the AMI. The paper further describes and implements a signature based station-to-station protocol for exchanging the secret shared keys among the AMI applications to get rid from undesirable security threats.

Selection of appropriate size of capacitance is very important to buildup voltage in a self-excited induction generator (SEIG). This paper proposes a simple method of determining the actual size of capacitance needed in a three-phase SEIG to obtain a pre-specified voltage under no-load and load conditions. The problem of determining the capacitance is formulated in a very general way so that the same set of equations and the solution technique can be used for both no-load and load conditions as well as for fixed and variable speed operations. Unlike most of the previous methods, explicit expression of the equations in terms of actual unknowns is not needed and thus the lengthy and tedious algebraic manipulations of the equations can be avoided. The formulated problem is then solved using a numerical based routine given in MATLAB. The proposed method is then tested on a three-phase, 220-V, 1.5-kW induction generator for various operating conditions. The simulation results obtained by the proposed method are also compared with the corresponding actual values found through an experimental setup and are observed to be in very good agreement.

The modelling and control of proton exchange membrane fuel cell (PEMFC) possesses great challenges due to PEMFC system's inherent nonlinearities, time-varying characteristics and tight operating constraints. In this paper, we propose a constrained model predictive control (MPC) strategy based on a combined empirical and mechanistic model of PEMFC. First, we propose a hybrid modelling approach based on the combination of prior knowledge, under the form of mechanistic submodel, with empirical submodel devoted to the extraction of knowledge from operating data. The empirical submodel is a SVM model, which predicts the voltage at different stack currents and temperatures under the reference hydrogen and oxygen partial pressure. The mechanistic submodel calculates the correction voltage by taking account of hydrogen and oxygen partial pressure changes. Particle swarm optimization (PSO) algorithm and penalty function are then employed to solve the resulting nonlinear constrained predictive control problem. Simulation results demonstrate that the proposed method can deal with the constraints and achieve satisfactory performance.

Repugnancies often appear between control behaviors of the real time optimal dispatch and the reserve regulations (containing primary, secondary and tertiary regulations). Real time optimal dispatch push the power system operating point toward the optimal point, but reserve regulations pull it deviated from the optimal point, it induces that the most operating points become non-optimal points. With the continuous increment in penetration of wind energy, the contradiction becomes gradually serious. Based upon the analysis of optimal point neighborhood, further research on the contradictions mentioned above is made in this paper. There are two important characters of the optimal point neighborhood: the broad characteristic of optimal point neighborhood and the non-sensitive characteristic of objective functions in optimal point neighborhood. In this paper these characters of optimal point neighborhood are opened out to deepen the understanding of the problems and point out the correct way of treating with the relationship between the real time optimal dispatch and the reserve regulations.

This paper proposed a bidirectional contactless power transfer (CPT) system with controllers at both primary and secondary sides to regulate the power flow. By involving energy feedback mode in the converters of both sides, a backward power flow channel from load to source is achieved which helps pumping out the surplus power from the output filter capacitor to the resonant tank at the secondary side and from the resonant tank to the power supply at the primary side. Furthermore, synchronous rectifying and zero current switching technologies are involved to reducing switching losses. Therefore, with the proposed dual-side control method, rapid regulation and high efficiency can be achieved. Simulation and experimental results show that the output voltage can be controlled to be constant against load variation by regulating the power flow direction dynamically.
