A self-calibrating wireless sensor network (WSN) of radiometers designed to detect PD radiation is proposed as a low-cost approach to real-time condition monitoring, asset management and operational optimization in the future smart grid. The principles of the proposed PD WSN are described in detail. Some early progress in the development of subsystems for a proof-of-principle prototype is also presented.

Energy conservation becomes more important nowadays. The use of smart meters and, in the near future, smart appliances, are the key to achieve reduction in energy consumption. This research proposes a non-intrusive appliance monitor and recognition system for implementation on an embedded system. The research focuses on computational efficiency of such a system as embedded systems usually have limited computation power. In this paper, research has been done on the effects on the accuracy of the sample frequency. The algorithm first detects an event in which an appliance is turned either on or off. Subsequently its profile is extracted. A hierarchical support vector machine (HSVM) is used to classify the appliance. The result is a complete algorithm that recognizes individual appliances within a household. Tests on this appliance recognizer show that the proposed algorithm can correctly detect appliances with reasonable accuracy.

Fault location research in compensated network has led to several ideas; from the classic use of the steady state to the use of the charging transient. This paper explores a new way to locate the fault in compensated network. The distribution networks have more and more loop structures which could bring significant information for the fault location. The proposed method uses the communications that can be brought by a smarter distribution network. Multiple measurements provide an implicit equation of the fault location. This equation reduces the use of badly known parameters. Monte Carlo results are presented to compare the method with single measurement point and the methods with two measurement points. Overhead lines and cables are both studied with PI line model in this paper. Homogeneous line is first studied and a more complex model is analyzed with heterogeneous line and its impact on the location accuracy.

To utilize renewable energy (RE) sources and energy storage will be common key components in smart grid vision. In Japan, a large scale penetration of photovoltaic generation is promoted, and there is a concern about its influence on load frequency control (LFC). Utilization of battery energy storage system (BESS) for LFC is expected as one of the countermeasures against it. In this paper, area control error (ACE) assignment suitable for making effective use of both of existing LFC unit and BESS is investigated under large-scale RE penetration condition. It is verified through numerical dynamic simulations that a filter-based ACE assignment can reduce the required capacity of BESS compared with a proportional ACE assignment.

The ADDRESS European project aims to develop a comprehensive commercial and technical framework for the development of “Active Demand” and the market-based exploitation of its benefits. In ADDRESS, “Active Demand” (AD) means the active participation of domestic and small commercial consumers in the electricity markets and in the provision of services to the other electricity system participants. This paper first recalls the project main concepts and briefly describes the proposed solutions. Then it gives an overview of the laboratory tests and the first results of the demonstrations that take place in three field test sites with different demographic and electricity supply characteristics in Italy, Spain and France. The first results of the consumers' acceptance study are also presented.

This paper presents big bang-big crunch (BB-BC) method for the optimization of preventive control action to enhance the dynamic security of the power system against transient instabilities. In the proposed approach, generation rescheduling is selected as a preventive control action and this control action is considered as a constrained optimization problems where the constraints are dynamic security of the system, generation limits and loading capabilities of transmission lines. The security constrained generation rescheduling is implemented through BB-BC method which optimizes the total fuel cost during the preventive control. The proposed method is applied to 50 generator 145 bus IEEE test system and the effectiveness of the approach is discussed.

The adaptive emergency control concept is based on realization of a tradeoff between preventive and emergency control by combining preventive and emergency actions. The paper proposes to complement the existing control strategies by predictive control strategy - adaptive emergency control, which implies identification of the emergency, until the emergency has occurred. In this paper presented the smart predictive voltage stability assessment (VSA) for the adaptive emergency control techniques on the basis of the artificial neural network methodology. The main idea of the smart predictive VSA here is a creation of a neural network model, based on a self-organized Kohonen map SOM that will be able to perform monitoring and prediction of emergency condition. Simulation results are obtained by the proposed scheme for different power system networks to assess the security level of the network.

Conditioning of network impedance by insertion of a virtual inductance as an inherent feature of the converter control system has the potential to extend the range of stable operation of the overall system. This paper presents a scenario in which such potential is explored and its range of application is identified. It shows first that implementation of a virtual inductance is naturally suited for combination with Virtual Flux-based control systems, and that it can be extended to the more general case of a virtual reactance. The paper then presents the structure of a control system for operation under unbalanced conditions, where the virtual inductance directly influences the current reference calculation. Compared with the standard approach of unity power factor control of grid integrated converters, the suggested technique allows for improving the stability range of converters operating in high-impedance grids, and for remote point control of reactive power or power factor.

Machine to machine (M2M) communication has been gaining momentum in recent years as a key enabling technology for a wide range of applications including smart grid, e-health, home/industrial automation, and smart cities. However, with the current communication systems mainly optimized for human to human communications, there are important capabilities that need to be developed in M2M systems in order to fully realize the new smart services enabled by M2M. In this paper, we provide an overview of M2M and its applications to smart grid. In particular, we discuss technical areas where data mining and machine learning can play an important role in realizing various smart functionalities in the future power grid. As a case study, we also present a novel phase identification technique in smart grid based on smart meter data. Preliminary results have demonstrated the effectiveness of the proposed algorithm.

The existing power systems are challenged as the share at MV distribution level of distributed generation is increasing. In order to ensure the security of operation and power quality in these grids, transmission and distribution power system operators have issued connection and operation guidelines related to integration of distributed generation. Some of these guidelines are designed to assess fault ride-through capabilities when dynamic connection studies are performed for distributed generation units. While most of the ongoing research have addressed especially the fault ride-through capabilities of the investigated generation unit when the most severe fault occur close to the point of common coupling, some research questions remain related to the adequacy of the representation of the external grid. This paper will compare several representations of external grid proposed by different authors for achieving more accurate results of fault ride-through capabilities of small scale hydro units.
