Although numerous proposals for electrical and communication topologies for distribution automation had been presented, not all of them are suitable for the use of renewable energy as a source of electricity. Selecting the most appropriate topology requires good knowledge of the particular characteristics and requirements. This paper presents the analysis of the basic characteristics, topologies and the main functions of the distribution network and evaluates the communication architecture suitable for a sustainable energy resources integration. Finally, recommendations for a new architecture are presented as well as for the communication to use.

This paper is part one of a two-part series discussing how Regulator requirements for continuity of supply could be incorporated in the reliability analysis of existing electricity networks and future “smart grids”. The paper uses examples of overall and guaranteed standards of performance from the UK and Italy, specifying requirements that network operators should satisfy with respect to excessively long and/or too frequent supply interruptions. Besides the relevant Regulator requirements, this paper presents input data, parameters and models required for comprehensive reliability assessment, while Part 2 paper presents scenarios and results for test network based on both analytical and probabilistic reliability procedures.

In this paper a concept of real-time reactive power control by electric vehicles is discussed. Electric vehicles pose potential issues for low-voltage distribution grids, such as violations of the minimum voltage boundary. Grid reinforcement can be prevented with innovative control concepts utilizing the existing power electronics in electric vehicles. The Fraunhofer Institute for Solar Energy Systems in Freiburg, Germany, developed and evaluated an on-board charging system featuring a four-quadrant charger and an on-board grid controller, the communication and control strategies. Simulation studies show significant effects in the low-voltage grid. The proof-of-principle was carried out in the lab, demonstrating the complete signal processing chain.

Demand side management (DSM) has become important for energy conservation and power system control. This paper proposes a technique that could be integrated into smart meters to identify two types of stress occurring within the electric power system across all three voltage levels, namely: high voltage (HV), medium voltage (MV) and low voltage (LV). Unlike other centralized approaches for smart grid control which are communication based, this technique only needs the voltage measurement from the local feeder and doesn't require real-time communication with a central controller. This technique uses the frequency to determine the HV network stress condition. For the MV level, a classification approach is used to detect switching events associated with the on-load tap changer (OLTC) transformer at the 33/11 kV substation; this allows the MV network's stress to be inferred. While the voltage behavior in the LV network is masked by the OLTC switching events in the MV network, this technique can unwind the effect of the tap changes and represent a real voltage behavior of the voltage measurement location. Knowledge of stresses occurring on all three levels would help to inform a strategy for DSM.

The location of power quality disturbances origin has been widely studied but remains unsolved so far. As disturbances location cannot be established, any evaluation regarding the cause of such disturbances cannot be completely provided either. The Method of Disturbances Interaction - MDI has proven to provide a solution to quantify the contribution of each circuit connected to a point of common coupling, allowing to identify where disturbances are concentrated. This paper goes further analysing the indicators derived from MDI in order to identify the causes of stationary power quality disturbances. Causality is evaluated by means of statistical procedures typically employed in epidemiology. Based on the results a novel discussion on responsibilities assignment is presented.

Fast Cut Back (FCB) thermal power units can be used as black-start units to boot up the power system after blackout. Based on the analysis of the important role of FCB units in restoring a power system, the optimal location of FCB units are determined with an optimization model. The objective function of this model is to minimize all the generators' restoration time, considering the constraints such as generating units' characteristics and transmission lines' charging time, etc. Such a model is computational intensive due to its combinational nature. Ordinal Optimization technique is thus applied in this paper as an efficient tool to obtain enough good solutions with a high probability. This technique succeeds in reducing the computational burden remarkably and well satisfies the engineering requirements. The simulation results of a practical power system prove that the reasonable location of FCB units based on the optimization can significantly contribute to reduce the restoration time.

Microgrid (MG) islanding is considered as an effective measure to minimize power outage and therefore to maximize usage of renewable energy resources. One of the most challenging technical difficulties associated with islanding is out-of-phase reclosing caused by asynchronism of MG with the electric power system (EPS). In this paper, a novel control methodology is proposed to synchronize MG with the main power grid so that smooth transition from islanded mode to grid-tied mode can be guaranteed. Synchronization is achieved by eliminating the voltage phase angle difference across the circuit breaker/recloser at the point of common coupling (PCC). The proposed control employs synchrophasor measurements transmitted via Internet Protocol (IP) communications. A MG hardware testbed with multiple distributed generators and loads is built to validate the performance of the proposed method.

A Virtual Power Plant (VPP) concept is utilized to manage multiple geographically dispersed energy resources. The purpose is to incorporate Distributed Energy Resources (DERs), Photovoltaic (PV) and energy storage units into the grid and to realize their economic and stable cooperation in a liberalized energy market. The paper proposed a centralized two-level hierarchical VPP controller to address both its commercial concerns and the participation into the energy market as well as the ancillary service market. The controller targets are attained with the Model Predictive Control (MPC) strategy, with different objective functions and constraints in the two levels. The primary control employs the Lasso MPC approach to allocate power imbalance commands between PV energy system and the Battery Energy Storage System (BESS). The secondary control mainly considers the income of the VPP, minimizing power purchase from the utility grid. Finally, a numerical demonstration is conducted using lumped system models, real weather and solar insolation data, as well as load data from the grid.

DC microgrid with multiple slack terminals has higher system reliability in case of slack terminal outage and communication failure. However, system bus voltage deviation from the nominal value and power sharing error are the main drawbacks of the droop-based distributed control. A three-level Energy Management System (EMS) is proposed in this paper to ensure both fast response and accurate control of the multiple-slack-terminal DC microgrid. All Energy Storages (ESs) are scheduled to operate in voltage regulation mode in level I control. The bus voltage regulation and power sharing among ESs are realized based on local bus voltage autonomously. In level II, bus voltage restoration and power sharing compensation are implemented to eliminate voltage deviation and power sharing error accordingly. Level III control takes the constraints of ESs' power capacity and energy capacity into consideration. Load shedding and generation curtailment are to be activated based on the real-time system net power and ESs' State of Charge (SoC). Case studies based on MATLAB simulation were carried out to verify the effectiveness of proposed methods.

This paper introduces the concept of prosumption control where intelligent loads and distributed generation are aggregated and controlled to improve power system security. It is expected that intelligent load and generation units can respond to control / market signals and thus present an opportunity of available resources for changing the operating point (OP) of a system to one that is more secure. A prosumption pattern is then a signal to prosumers to shift their demand in time. This makes it possible to temporarily change the distribution of the power demand. A prosumption pattern is balanced, such that frequency can be maintained by other smart grid technologies. To find a prosumption pattern which can improve security, it is necessary to determine sensitivities of stability indicators such that beneficial load permutations can be identified. After introducing prosumption control and patterns, stability indicators for aperiodic small signal angular stability (ASSA) are examined, while the concept of prosumption is described. The methodology presented is shown to be able to assess the margin to instability and to predict how this margin can be affected if a load is changed in the grid. The resulting sensitivities are described and their suitability to be used to search for a prosumption pattern is evaluated.
