Finding an optimal location for a Static Synchronous Series Compensator (SSSC) device in an electrical network can be a significant concern. In this paper, the use of Distributed Static Series Compensation (DSSC) is suggested to improve the voltage profile in LV 11 kV distribution networks and for network power flow control.

A large number of new and decentralized energy conversion systems (ECSs) in combination with renewable energy sources (RESs) have recently been integrated into the conventional grid to build up sustainable energy supply systems. This is one of main challenge of future smart grids. Thus, currently there are plenty researches focusing on the grid integration such as clustering concept. By clustering concept, it has a possibility to form the distributed generation (DG) units in a small group, which can establish an advance control function in order to make this small group to behave like a virtual power plant. Therefore, the grid integration can be completed in an easily way. However by adding the new grids, the fluctuation of dynamic behavior can cause the unstable power systems, for example, the voltage profile can temporally be out of the nominal rated condition. To avoid the unstable condition, the basic description such as the power flow between connected- or decoupling positions must be clarified and analyzed. In general analysis, the power system analysis needs to recreate the model structure when the new grid is joining the existing grids. This results in an increased complexity of power system analysis. Therefore, this paper introduces the decoupling power system analysis, which can analyze separately on each grid and no need to recreate new model when power systems structure is changed by adding the new grid. To validate the proposed method, the simulation case studies are provided and the results prove that the proposed method can be utilized as the general analysis method.

The paper adopts the Latin Hypercube Sampling with Dependence (LHSD) method to solve the Probabilistic Load Flow (PLF) problem with correlated random variables for distribution networks. The proposed method is investigated using modified IEEE 34 distribution system with random loads, Wind power and Photovoltaics (PVs). Three different cases are studied and the comparison results shows that the LHSD method handles correlations efficiently and presents an accurate simulation result with a much smaller simulation size. The method has the potential to be applied in many power system probabilistic problems.

Future smart cities are expected to be very large and complex ecosystems, where interactions among the various involved entities may lead to emergent behaviours (system of systems characteristic). Managing better the energy footprint is one of those challenging goals, and the smartgrid may provide a key tool in achieving that. We expect that smart city neighbourhoods will be more autonomous and able to manage more efficiently and dynamically their energy by taking into consideration local resources, prosumption and needs of their stakeholders. Additionally they will be able to interact with each-other and enable the smart city to dynamically take advantage of its optimal resource usage. We explore here directions that we follow in order to realize this view with the help of the smartgrid infrastructure, prosumer interactions, enterprise energy services and neighbourhood energy marketplaces.

Numerous studies have shown that households' consumption is an important part of the total energy consumed in different countries. However, there is very little work done on finding appropriate strategies of giving households' effective feedback on their energy consumption. This study analyzes several indicators that could be considered before analyzing residential overall energy consumption and providing information, feedback, or developing demand-response measures. A questionnaire sent out to 2000 households having 33% response rate shows that the total households' income and characteristics, occupants' age and users' energy attitudes and interest are the key components designing relevant energy information strategies.

A literature review of the existing developments in smart grid technology is provided which identifies the need for further development in tools to simulate the end-use stage of the smart grids. A new modelling tool which captures the electrical, heat transfer, communication and software control elements of domestic smart grid systems is presented. Following a description of the operation of this tool, a case study into a “smart” domestic heating system which can respond in real time to grid pricing signals is presented. Results of the modelling of this system in the new simulation tool are reported.

The paper will present the usage of Broadband Powerline (BPL) communication technology as a backbone communication infrastructure for smart metering and smart grid applications and systems. BPL provides transparent real-time TCP/IP communication over existing MV/LV grids. The technology is being used, for example, as the communications platform for the Smart City Mannheim (MoMa) project, where more than 10 000 BPL modems in total are deployed, covering most of the city area and giving access to BPL TCP/IP connectivity to more than 120 000 households.

In this paper we present the Active House industrial demonstrator, exhibited at the ELFACK fair (May 2011), which demonstrates the role of home/building automation systems in energy management at home. Moreover, we introduce the Active House deployment architecture in the smart grid that provides the basis for the industrial demonstrator. We discuss the demonstrator as the proof-of-concept that allows us to evaluate the applicability of the architectural solution and validate whether the Active House architecture can provide the right starting point for integrating the Active House into the grid.

The concern about the complete depletion of fossil fuels along with the negative environmental impact of most of the current energy sources are significant reasons to think of a different way to produce electrical energy and, at the same time, satisfy the necessities for urban mobility. In this context, microgrids (MGs) are power networks which, among other properties, allow more flexible demand consumption, and also help with, the efficient integration of renewable resources and electric vehicles (EVs). However, the effect of the incorporation of EVs has to be taken into consideration with care, since that situation may drive to unfeasible operations in grids which have not been designed to support these particular elements. In this paper, a system composed of different agents is used to develop a market-oriented operation in a MG with several EV charge stations. It is expected that the system takes to an optimal management allowing a technically feasible operation considering the behaviour of every agent involved. The demand shifting and the flexible operation of EVs, spatial and temporal, are features that reduce costs and thus improve the benefit of the participants.

The expected large-scale implementation of distributed generation (DG) requires a change in the current structure and operation of distribution networks. The future distribution network must be able to manage power flow in a bidirectional way, cope with uncertainties of renewable power generation and adjust to demands of more sophisticated customers. This paper introduces the concept of a power routing function to avoid congestion, minimize the operating cost, and adequately serve the requirements of customers. This function considers the optimal power flow as a problem of minimum cost flow in the graph theory. The Scaling Push-Relabel (SPR) algorithm is used to solve that problem. It will be implemented in a distributed agent environment which is suitable with a design concept of Active Distribution Networks. The performance of the power routing function is tested on a simulation of the medium voltage 32-bus network. Simulation results show the effectiveness and flexibility of the proposed function in dealing with issues of load demand increases and network configuration changes.
