Inverter Interfaced Distributed Generation (DG) in the Smart Grid has the potential to contribute to the reactive power support of the overall power system. However, because of the large numbers and distributed nature of the DG units, using a fully centralized communication structure to achieve coordination can be prohibitive. A decentralized coordination approach is a good candidate solution to address this problem. In the literature, asymptotic consensus based algorithms have been proposed, in order to coordinate a set of DG units so that they collectively provide a certain reference reactive power. This paper presents an alternative decentralized coordination methodology that achieves the same objective in finite time. The protocol is based on linear iterative updates and known observability results from graph structured linear systems. In this paper, the methodology is customized to solve the reactive support coordination problem from distribution-connected inverters and it is modified to reduce the number of operations per step, ensuring applicability to a large distribution network. The IEEE 37-node test feeder is used as a test system, with added inverter interfaced generation in each node. For this sample system, the proposed approach is shown to coordinate the nodes faster than the asymptotic consensus approach.

The next generation power grid demands high reliability, robustness and real time communication of control information related to power flow in the grid. This paper proposes a probabilistic framework of smart grid power network with statistical decision theory to evaluate system performance in steady state as well as under dynamical case and identify the probable critical links which can cause cascade failure. Proposed model for cascade failure prediction has been tested on the IEEE 30 bus test bed system. Simulation results validated critical links in probabilistic model of power grid system with deterministic power flow analysis. The key contribution of this paper is, performance evaluation of smart grid power network and identification as well as prediction of critical links which may lead to system blackout. In addition to this, a graphical model has been developed using minimum spanning tree to analyze topology and structural connectivity of IEEE 30 bus system.

One of the major challenges faced by the power sector of a developing country like India is the frequent power outages. Consumers are forced to spend money on back-up systems such as Diesel Generators. The depletion of fossil fuel necessitates the use of renewable energy sources such as solar energy. This paper presents strategies to reduce diesel power consumption which is twice as costly as grid power. To balance the shortage solar power is used along with strategies of Demand Side Management, to optimize the cost of the consumer. A day ahead DSM strategy is planned to enable the consumer to be equipped with required fuel for DG set. Graphical User Interfaces are developed to help the consumer know a priory the strategy with the cost saving increased for a particular consumer load pattern.

The continuous increase of power demand stresses the system, and adversely affects its security. It may lead to components overload and their outage, voltage decline and its collapse, which may cause entire system blackout. As well, the normal flow of power in transmission lines is not the best possible. In this paper, the Phase Angle Regulator (PAR) and Sen Transformer (ST) are suggested to be used for better utilization of the transmission lines, and to enhance power system security. In this work, the PAR and ST are modelled, and connected in a five bus test system using MATLAB/SIMULINK. The simulation results showed validity of both PAR and ST, and the superiority of ST, since it enhances both power flow and voltage security. Based on the results, the new emerging smart power and voltage control device ST is a very effective tool that can be combined into Smart Grids (SGs). It is found that, usage of ST not only manages line flow congestion and maintains bus voltage, but also increases overall efficiency.

Since busbar protection is the cornerstone of smart grid stability, a wireless sensor network (WSN) of distribution busbar protection is presented, and architecture of the WSN and busbar protection principles are proposed in this paper. The fault detection, analysis and judgment of WSN protection owns a unique feature but still has common characteristics with traditional protection scheme. Based on the traveling-wave generated in power system, when a fault occurs, a novel time synchronization scheme is employed to improve the protection performance and accuracy. Simulation results indicate that the scheme can acquire synchronization time and reduce the possibility of mis-operation of WSN based protection.

A new decentralized power oscillation dampers (POD) design of doubly-fed induction generator (DFIG) wind turbines for damping of inter-area oscillation is presented in this paper. The practical 2nd-order lead/lag compensator with single input signal is used for the POD structure. The POD is equipped with the voltage controller of rotor side converter of DFIG. With the damping signal from POD, the reactive power output of DFIG can be modulated to damp out the oscillations. The parameters optimization of decentralized PODs is conducted over a wide range of tie-line power flow levels so that the damping performance of PODs can be enhanced. The improved firefly algorithm is used to achieve the optimal POD parameters automatically. Study results in a two-area four-machine interconnected system show that the stabilizing effect of proposed decentralized POD is higher than the conventional POD under severe faults, heavy power flows, and wind speeds.

Electric vehicles (EVs) are considered to be an important component of distributed energy storage and supply devices in smart grids. EVs can serve as a distributed mobile energy resource in the electricity market. They can be used to store and transport energy from one geographical area to another as supportive energy supply. EVs should be included in future electricity demand management and consumption optimization system. This paper presents a dynamic optimization framework to formulate the optimal charging problem. The framework considers an aggregated charging station where a large number of EVs can be charged simultaneously during permitted time. The optimization will provide every individual EV an optimal charging strategy to proactively control their charging rates in order to minimise the charging costs. The optimization is based on stochastic optimal control methods. Numerical results are presented to demonstrate the proposed framework.
