    ABSTRACT: An approach to modelling of electrical and thermo-physical properties in small cylindrical volumes of cable insulation, that is, insulation spot samples is presented in this paper. Apart from small leakage currents, high currents can flow through these spots under fault conditions, at the same time heating up and destroying the cable insulation in them as well. An introduction of models for electrical and thermo-physical properties of the insulation to the nonlinear thermal finite element method (FEM) analysis of faults is demonstrated on the examples of short circuits that occurred in buried power cables. Nonlinearity of the thermal FEM model is based on the heat sources, electrical and thermo-physical properties of polyvinyl-chloride and cross-linked polyethylene insulation as functions of temperature and/or time. According to the DIN VDE standards, the cable structures considered herein correspond to the NAYY 4×120 SM 0.6/1 kV and NA2XY 4×120 SM 0.6/1-kV cables. The proposed models for insulation properties are applicable to the fault thermal FEM analysis of all multi-core power cables laid in the soils, air or water.

    ABSTRACT: This paper examines the ability of the doubly fed induction generator (DFIG) to deliver multiple reactive power objectives during variable wind conditions. The reactive power requirement is decomposed based on various control objectives (e.g. power factor control, voltage control, loss minimisation, and flicker mitigation) defined around different time frames (i.e. seconds, minutes, and hourly), and the control reference is generated by aggregating the individual reactive power requirement for each control strategy. A novel coordinated controller is implemented for the rotor-side converter and the grid-side converter considering their capability curves and illustrating that it can effectively utilise the aggregated DFIG reactive power capability for system performance enhancement. The performance of the multi-objective strategy is examined for a range of wind and network conditions, and it is shown that for the majority of the scenarios, more than 92% of the main control objective can be achieved while introducing the integrated flicker control scheme with the main reactive power control scheme. Therefore, optimal control coordination across the different control strategies can maximise the availability of ancillary services from DFIG-based wind farms without additional dynamic reactive power devices being installed in power networks.

    ABSTRACT: SUMMARY Current and force calculations in different short-circuit conditions are required for short-circuit performance analysis of a multi-winding traction transformer which is one of the most important requirements in its design process. This paper extends the available low-frequency three-winding star equivalent circuits to develop a novel equivalent circuit for the four-winding traction transformers. The leakage inductances of the traction transformer are determined and employed to calculate the parameters of this developed star model. It is shown that the star equivalent circuit is a valid and appropriate model to simulate the steady-state and dynamic performance of the traction transformer under different short-circuit conditions. To analyze the short-circuit performance of the transformer, the short-circuit currents (simulated by the introduced model) are employed to compute the electromagnetic forces for a typical dry-type traction transformer. The analytical and numerical methods are used for short-circuit force calculations, and those results are compared against each other. Copyright © 2012 John Wiley & Sons, Ltd.

    ABSTRACT: SUMMARY High penetration of distributed energy resources (DERs) has led to considerable evolution in the operational aspects of distribution systems. As a result, distribution companies (DISCOs) tend to utilize optimization in order to schedule their DERs to meet their demand as well as participation in the electricity markets. This study presents a comprehensive operation model for a distribution system which involves DISCO participation in energy production and reserve providing activities. The uncertainties are modeled by means of a chance constraint representing the confidence level of serving load by DISCO. The presented model can incorporate DERs (both dispatchable and non-dispatchable units) along with network constraints and load and wind uncertainties in order to achieve optimal decisions in both day-ahead energy and reserve markets. A modified 32-bus distribution network including dispatchable generators, electric energy storage, wind turbine units, interruptible loads, and interties is employed to illustrate the effectiveness and feasibility of the proposed method.

    ABSTRACT: This paper analyzes two control strategies of doubly fed induction generator (DFIG )-based wind turbine under unbalance d voltage which were introduced in the previou s works and then propos es a new control strategy to achiev e m o r e improved performanc e o f DFIG. Under unba lanced con ditions, the rotor si de converte r (RSC) and grid side con verter (GSC) are con trolled in two positive and negati ve ((dq) + and (dq) – ) reference frames . The control of these con verters in the (dq) + frame is the same as the conve ntional control under balanc ed grid conditions . I n the proposed con trol st rategy, the control of the RSC in the (dq) – frame is done to balance the stator currents, and also the total active power oscillations are removed by the control of the GS C i n this frame. In this strategy, the oscillati ons of both the torque and stator active power are prope rly redu ced even when the voltage unbalance is some what seve re. Consequen tly, the elimination of the stator active power oscillati on by the active power output from the GSC is acc omplished with fewer constraints. To provide t he accu ra te co or di na te d c on tr ol of the R SC and GSC, t hi s p ro po se d control strategy is implemente d in t he stator-v ol tage orie nted fr am e. The s im ul ation r es ul ts obtained fo r a 7.5-kW DFIG-b as ed wind tu rb in e v al id at e t he enhancement o f s ys tem o pe ra ti on using t he proposed control strategy during unbalanced volt age net work

    ABSTRACT: In this paper, the least squares support vector machines (LS‐SVMs) based design of superconducting magnetic energy storage (SMES) controller is proposed for wide area stability control. The LS‐SVMs for SMES controllers are trained by local and inter‐area data based on synchronized phasor measurements considering time delay. A large amount of training data set of a multi‐machine power system is reduced by the measurement of similarity among samples. The LS‐SVM parameters and the similarity threshold are optimized by a particle swarm optimization. Subsequently, the redundant data in the training set can be discarded while the reduced data are the optimal support vectors in the LS‐SVM model. The LS‐SVM control signals can be adapted by various operating conditions and different disturbances. Simulation results in a six‐area West Japan interconnected power system demonstrate that the proposed LS‐SVM for SMES controller is robust to various disturbances under wide range of operating conditions in comparison to the conventional SMES.

    ABSTRACT: In many papers, in dealing with bifurcation analysis of power systems, the power system is modelled as an ordinary differential equation system, in order to conveniently use the theory and numerical tools developed for bifurcation analysis of ordinary differential equation systems. We explain in this work how state‐of‐the‐art numerical techniques for bifurcation analysis, not well known in the power system community, can be extended to the more conventional power system model, that is a differential algebraic equation system, including power system specifics such as limits. Bordered matrices are extensively used, notably for the detection and exact localisation of singular points, as well as their continuation in two‐parameter continuation. The methods are tested on a simple power system with grid‐connected voltage source converter. Copyright © 2011 John Wiley & Sons, Ltd.

    ABSTRACT: The improved transmission line (ITL) model of a grounding grid has been already used in engineering practice for a grounding grid transient analysis. This article offers a progress to the ITL model of a grounding grid on the basis of the finite element method, where ITL model is developed using finite element method applied to the system of multiconductor telegrapher equations. To check accuracy of the proposed method, the results obtained using ITL approach has been compared with the results calculated using electromagnetic field approach and very good correlation has been obtained.
