A multiagent system (MAS) is proposed for managing energy on a microgrid (MG). Buses in the MG constitute different electrical zones, which are coordinated by an agent who shares information amongst the other agents. An optimal formulation is solved on a decentralized manner coordinated by such agents in order to manage the energy of the wind, the sun, conventional sources, and elements of storage. Results are promising for attaining a simple and rapid way to manage the microgrid's energy.

Most of transmission line faults are line to ground and most of them are transitory in nature. In this sense, high speed auto reclosing improves the system stability, but there must be certainty that the arc has been extinguished. For shunt compensated transmission lines, frequently, an additional singlephase reactor is connected between neutral and ground. This reactor contributes to coupling reduction and is important to reduce secondary arc current amplitude, which in turn will decrease the secondary arc extinction time during single pole reclosing This paper examines different aspects related to the neutral reactor optimization and its effects for arc extinction time reduction during three-phase reclosing. Additionally, the result of applying a switching method to reduce overvoltages during three-phase reclosing is presented.

This article presents the development of a portable stand-alone photovoltaic system (SAPS) and the mathematical model that allows simulating its behavior and optimizing the design. The purpose of this system is developing an auxiliary source of energy for portable information and communication technologies devices (ICTs). The SAPS was implemented from a 20 Wp foldable photovoltaic generator and a 5200 mAh Ion-Lithium battery bank linked to a netbook from the Programa Conectar Igualdad of Argentina (PCI). The model validation was carried out through experimental results obtained by testing a specific application of this type of systems. The results demonstrate an optimization of the equipment fed by the system (netbook), increasing autonomy by 5 hours on a clear day in a month of winter in the city of Corrientes, Argentina. By comparing the theoretical and experimental results it was possible to verify an adequate development of the system for the specific application and the utility of the model as a systems design tool for this type of applications

The problem of improving the quality of electricity in medium voltage (MV) distribution electric networks (DEN) can be solved with the help of intelligent semiconductor booster devices. A variant of such a device is the thyristor regulator of booster voltage (TRBV), developed by the NNSTU. The operation of semiconductor devices causes a non-sinusoidal voltage of the network. The article is devoted to the investigation of the TRBV output voltage harmonic composition. The developed Simulinkmodel of a MV DEN segment with TRBV allows conducting the research. The modes of the longitudinal, transverse and longitudinal-transverse voltage regulation are considered. The output voltage of the TRBV meets the requirements of the regulatory standards.

This paper studies the possible benefits/overcharges for a Distribution Network Operator (DNO) in the process of Planning the Distribution Network, when Distributed Generation (DG), and/or Demand Response (DR) policies are incorporated in the Distribution network. The results obtained for the design of the new grid with this participation are incorporated into the network planning process with different types of DG power plants and DR in their demand nodes, compared with the base case of demand obtained in the case of a network without changes in their consumption patterns neither DG incorporation. For the planning process of the new network in either cases, the classic Distribution Network Planning methodology was used, which is based on the classic economic theory of Minimum Total Cost (MTC) through which the Investment Plan of the Distribution Network of the Electrical Distribution Company is drawn up. The solutions obtained guarantee the supply of the power and energy demand of its customers at all times (all scenarios), minimizing the total cost equation and complying with the physical design constraints during the network planning horizon of 20 years. A genetic algorithm (GA) was used to search for the optimal solution (minim total cost) in a technical-economic point of view of the electricity network.

This paper proposes a methodology of integrated generation-transmission planning of power systems, that considers the penetration of renewable generation sources to be shared by two AC independent systems. Additionally, the methodology also deals with the interconnection of independent AC systems by means of HVDC grids. The methodology makes use of differential evolution optimization algorithms to search the optimal solution of the configuration of the HVDC grid. The methodology is tested on a proposed test system that interconnects IEEE-RTS system and the IEEE 39 bus system and two large generation sources, one a wind farm and the other one large hydroelectric source.

This paper presents a methodology for analyzing the feasibility of the insertion of energy storage systems in electric distribution networks due to different regulatory policies. Various topologies are used as input data, and as output, we have the maximum possible cost that the energy storage system may have to be considered viable by the potential investor. With the input data is possible any combination of these 8 regulatory policies, generating 255 scenarios for evaluation. For each scenario, the possible revenue was estimated, with each one scenario generating 441 sub-scenarios resulting from the test of several levels of WACC and taxes. Thus, in all, there are 112,455 possible regulatory configurations for evaluation. Based on the calculation of cash flow in each sub-scenario, the work determined the maximum possible cost in each of these. The proposed method allows the validation of which energy storage technologies are feasible or not, and which technological development they need to achieve considering the regulatory framework in which they are inserted. Through simulations with standard distribution networks using worldwide economical reference values, it is possible to determine which changes regulatory agents must make to enable the rise of storage systems in power distribution networks.

Changes in electric grid structure and dynamics are driving utilities and grid operators towards the need of better awareness of state of entire electric grid, from distribution system to end-user asset control and coordination. However, a complete, comprehensive and integrated situational awareness (information) of the dynamic state of the overall grid is lacking due to not enough sensing devices in critical location. The barrier to deploying more sensors are cost, complexity and data overload. This paper addresses fundamental functional requirements for new electrical transducers for the smart grid, from electrical performance to cyber-security aspects.
