As HVDC transmission is increasingly used in electric power grids its influence on overall voltage and power stability is under special focus. For the classic HVDC system using current sourced line-commutated converters voltage and power stability is of concern. For the light type of HVDC systems utilizing voltage sourced self-commuting converters voltage stability is in general no problem, however, transmission angle stability and, connected to this, power stability can be crucial. Essential for both types of HVDC system is the identification of unstable operating regions and their avoidance. Certain off-line analytical methods and on-line control concepts exist but they do not provide complete security. This paper demonstrates that a real-time stability analyzer and an adaptive power controller free the system from this risk of voltage and power instability. Voltage and power are stabilized at a maximum transferable power level.

Electricity networks operators must operate their network with a high degree of efficiency and reliability. Presently the drivers for lower-carbon electricity generation technologies are high, and to accommodate such technologies (e.g. large-scale wind power), significant changes have to be made to the way that Transmission and Distribution (T&D) networks are designed and operated. The Smart Grid concept has been introduced to highlight alternative, automated technologies that may bring significant benefits to the T&D networks. This paper summarizes smart grid technologies within the T&D sector that in terms of technology readiness are superior to other technologies, and are expected to be deployed in the near future. This paper summarizes the drivers behind development of the smart grid, then by introducing some smart grid technologies, their potential applications and benefits are discussed. The engineering challenges which may prevent large scale deployment of smart grid technologies is discussed

While the smart grid dream is likely to be revisited, we are witnessing a convergence of Information Technology (IT) with power system engineering. This convergence should be managed tactfully, to obtain a consistent architecture for the smart grid. Due to the complex nature of the both IT and power systems, a higher degree of complexity emerges through the smart grid. Therefore, selection of the right IT infrastructure for the smart grid is a complicated decision making problem. However, many of these decisions are made based on personal expertise, ad hoc methods and heuristic rules. They not only are highly suspected of not being optimal, but also are prone to serious mistakes. This mandates a consistent decision making method for the selection of the IT infrastructure in the smart grid. In this paper, Wymorian Tricotyledon Theory of Systems Design (T3SD) and Fuzzy Data Envelopment Analysis (FDEA), as a variation of Data Envelopment Analysis (DEA) and being capable of handling uncertainty, are employed as a decision supporting tool, to encompass the real world selection and decision issues which is presented as T3SD Fuzzy DEA method.
虽然智能电网的梦想可能会被重新审视，但我们正在见证信息技术(IT)与电力系统工程的融合。必须巧妙地管理这种融合，以获得一致的智能电网体系结构。由于IT系统和电力系统的复杂性，智能电网的复杂性更高。因此，为智能电网选择合适的IT基础设施是一个复杂的决策问题。然而，这些决定中的许多都是基于个人专业知识、特别方法和启发式规则做出的。他们不仅被高度怀疑不是最优的，而且容易犯严重的错误。这要求采用一致的决策制定方法来选择智能电网中的IT基础设施。本文将Wymorian Tricotyledon Theory of Systems Design (T3SD)和模糊数据包络分析(FDEA)作为数据包络分析(DEA)的一种变体，具有处理不确定性的能力，作为一种决策支持工具，将现实世界的选择和决策问题纳入其中，称为T3SD模糊包络分析方法。

A typical power system voltage collapse scenarios is often ended with the undesirable operation of the Zone-3 distance relay of the transmission lines. This paper presents a protection scheme to avoid power system voltage collapse using a combined method of distance relay's Zone-3 blocking scheme and a sensitivity-based load shedding selection. The Zone-3 distance relay blocking is based on the proper differentiation between transmission line overloading and line faulted conditions, using a fast estimation of power flow based on Line Outage Distribution Factor (LODF) and Generation Shift Factor (GSF). The Zone-3 distance relay of the transmission line would be blocked if the power flow change over the line is determined to be due to an overload so that more time would be available for the system to take necessary control actions. One of the important control actions is the emergency load shedding. A method based on the calculated sensitivities GSF to identify the most effective load shedding positions and amounts is proposed. The proposed method has been implemented in the Advanced Real-Time Interactive Simulator for Training and Operation (ARISTO) software with the Nordic 32-bus test system. ARISTO offers the possibility to test the proposed scheme since it can be seen as the virtual power system with all live information. The analyses of power system voltage collapse scenarios with and without the proposed scheme implemented have shown the effectiveness of the scheme to prevent the voltage collapses.

Higher percentages of wind generation are anticipated to reduce effective inertia on the electric power grid, presenting challenges to electromechanical stability. Two technologies will help mitigate these stability problems: (i) advanced control systems on wind turbines, exploiting Phasor Measurement Units (PMUs), and (ii) deployment of controllable energy storage. This paper extends state feedback-based, centrally-coordinated control design for energy storage and wind generation to consider distributed, observer-based implementations. Establishing that a local bus PMU measurement at each controller is inappropriate, we demonstrate the feasibility of limiting each local controller to a very small set of remote PMU measurements. An approach is developed that characterizes the practical degree of observability achieved on a subspace of lightly damped electromechanical modes of interest. In a representative power system model, the measurement selection methodology and local observer design is shown to yield control performance very closely approximating that obtained in the centralized, full state feedback case.

This paper presents a modeling of photovoltaic (PV) module in PSCAD/EMTDC and design of maximum power point tracking (MPPT) using boost converter. The model can be used for simulation studies of grid interface applications using voltage source converter in the PSCAD. The validity of the PV model developed has been verified using the set of data collected experimentally. In order to extract maximum power from the PV module the boost converter can be controlled through the Hill Top algorithm. All the simulation study has been done in the PSCAD/EMTDC simulation software.

This paper presents the theory, design and implementation of two real time virtual instruments to measure the power quality indices such as current harmonic distortion, voltage harmonic distortion and power factor as given by the IEEE standard. Different windowing techniques are explored in the estimation of the spectra. Cross spectral analysis is used for the measurement of phase angles in voltage and current signal. The virtual instrument integrates digital signal processing (DSP) methods such as windowing techniques and Cross-spectral density estimation with Welch spectral estimation to calculate voltage and current phasors. Moreover a tunable Kalman filter with a forgetting factor is applied to further enhance the results due to noise in the measurement. Simulations followed by a real time experiment using a rectified AC waveform applied across an RL circuit is followed to support the theoretical claims and further to show the robustness of the virtual instruments. Finally the two instruments are compared with each other in terms of performance and speed.

The current transition from passive to active electric distribution networks comes with problems and challenges on bi-directional power flow in the network and the uncertainty in the forecast of power generation from grid-connected renewable and distributed energy sources. The power flow management would need to be distributed, flexible, and intelligent in order to cope with these challenges. Considering the optimal power flow (OPF) problem as a minimum cost flow represented with the graph, this paper applies a cost-scaling push-relabel algorithm in order to solve the OPF in a distributed agent environment. The algorithm's performance is compared with the successive shortest path algorithm developed in our previous work. The simulation is implemented for both meshed and radial networks. The simulation results show the advantages of the cost-scaling push-relabel algorithm over the shortest path algorithm in the radial networks with respect to significantly reduced number of exchanged messages on the agent platform, and thus the reduced time for calculation. This will be of great importance if the method is to be applied to a large system.

This paper discusses the modeling of single-diode photovoltaic cell to estimate the maximum power with respect to changes in environmental factors that effects its efficiency performance. The parameters, i.e. resistances for the modeling of PV cell are determined for nonlinear I-V characteristics to replicate the maximum power point. These values are determined at various environmental factors like; dust, solar radiation intensity, shadow, temperature and wind velocity.

Induced by a very unfavorable scenario of nontechnical losses (electricity theft), some electrical distribution companies in Brazil have moved from the traditional one meter per residence measurement process to a centralized multi-residences meter with two-way communication features, enabling both automatic reads and remote connect/disconnect of energy supplies. Those improvements can be seen as a natural transition toward an effective Smart grid, and have brought together the needs of a deep revision on regulatory procedures for the electrical meters evaluation conducted by the Brazilian Metrology Office. This paper shows that the increasing complexity from those new electrical grid equipments, particularly conveyed by additional software procedures, is a major issue and needs to be rapidly assimilated by metrological controls to avoid the appearance of stepping stones in the smart grid pathway. This paper aims to describe the whole set of relevant aspects revealed in this particular Brazilian experience, discussing the real scene and the respective challenges opposed.
