The penetration of wind energy in power system is growing dramatically world wide. Consequently, there are some new challenges appeared on power system. Smart demand technology involves new communication technologies to make sure actions can be fast enough to prevent instability situation of generators. Due to the high level of renewable energy in power system, flexible demand becomes a future option for wind intermittency situation. Intertrip is one of the automatic actions that can help release overload and stability situation. It is normally used for generations to be disconnected followed by a trip of circuit. It can also be used for demand side intertrip. This paper will show how demand disconnection and intertripping technology can improve power system stability. Power Transfer Distribution Factor (PTDF) will be used to define wind transfer corridor circuits. After the corridor is located, the sensitivity of individual demand will be calculated by using PTDF method. This sensitivity factor will be used to select demand intertrip accordingly. It is defined as smart intertrip controller in the paper. A reduced UK model will be used in the paper to prove how demand side intertrip technology can improve system stability during high wind scenario.

Information and communication infrastructure inevitably impact the control and monitoring of smart grid. Smart grid communication need to be reliable, high-efficiency, secure and real-time. This is demanded by the flexible integration of units such as distributed generators, smart meters, dynamic demand-side response, and smart appliances etc. Conventional power grid communication requires upgrading but special and dedicated communication networks are feasible for distribution system due to high costs and long construction time. Data distribution service is a new data delivery service that can addressed the communication challenges causes by distributed energy management. The middleware technology can provide fast prototyping way to provide an efficient and reliable data communication for smart micro-grid monitoring. The purpose of this paper is presenting an implementation of DDS middleware based data monitoring in smart micro-grid.

Evaluation of the field performance of composite insulators is essential for maintaining the desired levels of reliability in power networks. Field performance of composite insulators depends on many factors, including the insulator design, material quality and service conditions experienced. The most critical part of the composite insulator is its external housing, usually made of silicone rubber having the advantage of recovering its hydrophobic properties in polluted conditions. Thus, condition assessment of the hydrophobic properties of the housing material especially under erosion and tracking processes is of major importance. In this study performance evaluation of the housing material of 150 kV field-aged silicone rubber insulators is carried out through physical, electrical and material analysis techniques. The hydrophobic properties of the housing material were found degraded to a different extent between field-aged insulators due to differences in material structure and pollution conditions. Hydrophobicity can be better assessed if the relevant diagnostic techniques are also applied after inclined plane tests.

Reconfiguration of a power distribution system consists in changing the functional links among its elements and represents one of the most important actions for the improvement of system performance in operation. In the last few years, some authors have proposed approaches based on Pareto optimality for problem formulation of reconfiguration, with active power losses and reliability indices as objectives. The study highlights the optimization importance of reliability indices which refer to the interruption frequency, especially because, in the context of smart grids, the fastness of the reconfiguration method contributes, by itself, to reduce the duration of interruptions. There is no unique recognition concerning which approach is the most suitable to be used in order to solve the reconfiguration as a Pareto-optimal problem. The most important aspect is the way in which the specific information of the problem field is modelled in the implementation. Also, the dimension of a Pareto-front can vary widely from a test system to another.

As a consequence of higher levels of wind generation on power systems, the inertia which has been provided by conventional synchronous generators is reduced as a result of the introduction of newer, variable speed generators. This includes double-fed induction generators (DFIG) and fully rated converter generators (FRCG). With reduced system inertia, the likelihood of higher rate of change of frequency (RoCoF) levels in response to major system events is increased. Higher RoCoF has possible implications for conventional generation and can cause inadvertent tripping of anti-islanding protection systems. This paper presents the simulation results of a model power system with varying levels of wind generation penetration and examines the possible measures available to enhance inertia. In particular, the paper considers the control system requirements for wind generators providing emulated inertia capabilities.

The paper deals with a microcogenerator prototype of 10 kW of electric power and about 20 kW of thermal power, suitable for indipendent local grids (such as small farms or small residential sites) fuelled by gas produced from biomass (both gasifiers or biogas plants). Small power systems (i.e. about 10 kW of electric power) are not optimized to be fed by low heat value gaseous fuels produced by gasifier or biomass plants or blends of them. Most of them have been provided with induction generators and conceived to be grid connected, while in most cases these plants must represent a form of indipendent energy production system, so not making easily possible their running in remote locations. The protoype presented in the paper was conceived since the beginning in the simplest way: the internal combustion engine maintains many technical solutions and constructive elements adopted for a previous prototype derived from a Diesel automotive engine, then converted in a spark ignition unit. The same has been modified in order to be multi-fuelled and compliant with different blends of methane, LPG, and other mixtures of combustible gasses deriving from biomass conversion. This last aspect asked for deep modification of the unit itself, if compared to previous prototypes, but gave a clear flexibility in terms of different fuels. The electric generator is a permanent magnet generator fed by a simple inverter which is a good solution for islanded systems.

Romanian Balancing Market is enforced since July 2005 when Romanian Operator Transmission and System (CN TRANSELECTRICA SA) begun the activity as Balancing Market Operator. Since then, the Romanian Balancing Market was based on the Wholesale Electricity Commercial Code which was published in 2004. After some years of activity and operation of Balancing Market, the Romanian Regulatory Authority proposed a new Wholesale Electricity Commercial Code which is under discussion since 2007. The new Commercial Code proposes some modification especially on the Settlement chapters. The present paper proposes to compare the resulting prices on Secondary Regulation.

Smart Grid has been characterized as the next generation power grid in which modern Information and Communication Technologies (ICT) will improve control, reliability and safety. Although the adoption of generic off-the-shelf ICT in Smart Grid provisions indisputable advantages and benefits, it raises several issues concerning the reliability and security of communications - the core infrastructure of Smart Grid. Cloud computing has developed and evolved over the past years becoming a real choice for Smart Grids infrastructure because of the availability, scalability, performance and interoperability that it offers. In this paper we present a survey of the existing cloud-based software platforms for implementing secure Smart Grids. Security issues like authentication and authorization of users, data encryption, availability, attacker impact, detection and trust management have received significant attention in previous work. Nevertheless, as shown in this paper, their integration and adaptation to emerging fields such as Smart Grid is still in an embryonic state. As such, we report recent advancements and software platforms specifically for Smart Grid and we outline several issues as well as suggestions for designing security-aware platforms for Smart Grid.

Offshore wind power generation is expected to increase in the following years, but there are still some economic and technical challenges to overcome. Because of the difficult access to the offshore facilities, the reduction of maintenance is an essential point. The use of Permanent Magnet Synchronous Generators (PMSG) is considered a suitable option in this wind farm topology to satisfy this purpose. On the other hand, these generators along with full-rated Voltage Source Converters (VSC) are expected to provide ancillary services for the onshore AC grid. Particularly, Inertial Frequency Response is an interesting option considering the stored kinetic energy in the rotor of the wind turbines. Therefore, in this paper a description of the model and control system of a PMSG using full-rated VSC are reviewed and their Inertial Frequency Response capability is presented through two methodologies. At the end, simulation and experimental tests results are shown in order to compare these two different options and analyse their viability.
