The paper discusses reactive power-voltage (Q-V) control in a multi-machine steam power plant (SPP). After briefly introducing some of the basic characteristics of synchronous generator's voltage control through automatic voltage regulators, the practices of widely applied manual voltage references setting for Q-V control in SPP is illustrated through several examples of SPP response recorded at site. Further the case studies were developed with the emphasis on the drawbacks of manual intra-plant Q-V control by building a mathematical model of realistic SPP in Matlab-Simulink. Relying on noticed drawbacks the paper highlights the requirements for enhancing SPP reactive power response and voltage support to the power system by coordinated Q-V control at power plant level. Finally, the paper illustrates the achieved performances of coordinated Q-V controller in real SPP.

The New Zealand Electricity Market (NZEM) is a locational marginal price (LMP) market. The market clearing engine, called Scheduling Pricing and Dispatch (SPD), is based on security constrained DC OPF and is formulated as a Linear programming problem (LPP). There are significant differences between how SPD calculates the LMPs at each node and those calculated in many other LMP markets. In the NZEM, the LMP which is the dual variable associated with power balance equality constraint captures all three cost components readily available in the SPD solution. These three components are marginal cost of generation, marginal cost of losses and the marginal cost of network congestion. SPD currently uses a piece-wise linear loss model to capture the losses of each branch. The objective of this paper is to present difference in losses with the number of linear loss segments, and highlight the problems encountered by such models.

This paper presents a distributed Flywheel Energy Storage System (FESS) for mitigating the effects of pulsed loads such as those exist in Shipboard Power Systems (SPS). A comparison between distributed and centralized allocation of FESS was provided with and without the utilization of ultra-capacitors on the DC side. A model for hybrid AC/DC SPS with zonal distribution architecture was built in a simulation software. In order to accurately evaluate the performance of the system, three different case studies are presented with and without the FESS. The results of each case are analyzed and discussed. It can be shown that the distributed allocation of FESS can reduce the overloading on the generators and frequency fluctuations.

It is described that controlling or shedding by price the power consumption of a population of thermostatic loads introduces in the aggregate consumption dynamic effects that cannot be disregarded if electrical flexible demand is meant to supply power system services. It is shown that inducing a desynchronization in the consumption contributes to damp the oscillations. Results are supported by Monte Carlo simulations of a population of buildings equipped with electric space heating whose consumption is indirect controlled by a dynamic price of the electricity.

Summary form only given. This paper presents a new planning expansion model of an electricity and natural gas distribution system that has high penetration of distributed generation based on natural gas. The model entails lower investment costs as compared to traditional planning models that consider both systems (electricity and natural gas) as independent networks. This model is especially convenient for utilities that own both systems, as electricity and natural gas customers can derive benefits (via electricity or natural gas tariffs) if there are significant savings in investment costs. For fast-growing economies, the merging of electricity and natural gas distribution systems is seen as a promising business opportunity in which economies of scope can have lower investment costs, so there is a definite need for this type of approach.

The paper presents a method of designing a low order robust wide-area damping controller (WADC) for large-scale photovoltaic (PV) power plants. The controller design procedure is focused on designing a second-order wide-area damping controller by convex optimization method. A Hankel singular value (HSV) based hybrid signal selection method is also proposed for optimal selection of the control signal. The performance of the synthesized controller is investigated on a 16-machine 68-bus system, typically used for power system oscillation studies.

Series Flexible AC Transmission Systems (FACTS) devices have been employed to increase power transfer capability of transmission networks and to provide direct control of power flow over designated transmission routes. However, high costs and reliability concerns associated with implementing one large FACTS device capable of altering the power flow in a wide transmission network have limited widespread deployment of FACTS solutions. Recently, concept of Distributed FACTS (D-FACTS) was proposed as an alternative approach to realize cost-effective power flow control through multiple, small, fixed series impedance injections. This paper extends the functionality of D-FACTS concept by introducing variability in impedance injection of D-FACTS devices, thereby improving their controllability. Furthermore, this paper also presents a more detailed analytical treatment of such a topology termed enhanced Power Flow Controller (ePFC). It is shown that employing 1st order (assume s sinusoidal voltage across compensation capacitor) and 2nd order (assumes sinusoidal current in the transmission line) fundamental impedance model are inaccurate methods to analyze effective impedance inserted by ePFC. Instead, a new mathematical model that is based on sinusoidal voltage difference between two end buses is proposed. The efficacy of this approach and its advantages as compared to existing models are presented.

Summary form only given. The complexity of the power systems is increasing. More and more generations based on renewable energy are installed in the system. Some are dispersed (PV in distribution system) or others far way from load centers (off shore wind). They are generally intermittent (day ahead forecasts are not very accurate). TSOs have a lot of difficulties to build overhead power lines. People don't like their impact on the landscape and they are now afraid of hypothetical effect of EMF on health. We must use more complex solutions: numerous Phase Shifters Transformers, upgrades of existing corridors by using new conductors (ACSS), underground cables, HVDC links embedded in AC systems. The Single European Electricity market is an optimizer which maximizes the use of existing assets, pushing the system to its limits. To operate such a very large and complex system, new tools are needed to help operators to make decisions. One of the challenges is the very large scale, the full European system must be taken into account, electrical phenomena don't stop at administrative borders, (10000 electrical buses, 2000 generators, 100 PSTs, 10 HVDC links, ...). More and more post-fault actions are implemented to control the system using topological actions and flexible devices (PST, HVDC link,). In iTesla, ongoing project funded by the European Commission, we propose to develop a platform to offer solutions to tackle some of these issues. The Online Security Assessment is based on “Dynamic Security Assessment”. Corrective or remedial actions are performed after the occurrence of a fault, they are post-fault actions. The actions are event-based or measurement-based. They are implemented via automatic devices (SPS) or human actions (operating rules in control rooms). Interactions between these multi-actions can't be easily understood without a time domain simulation. The possible failure of one of these corrective actions implemented through IT systems which can't be considered as hundred percent reliable, must be considered. Moreover, post-fault steady states depend on the trajectory and can't any longer be computed using a conventional power flow. We are operating the system with less margin and unstable dynamic phenomena could appear (for example, poorly damped inter area oscillation). Local dynamic problems (for example, Voltage collapse or transient stability issue) could initiate a cascade of events leading to a very large blackout. The only practical tool available today to assess these possible phenomena is time domain simulation. This time domain simulation must cover the whole Pan-European system which is a very large system (around 125.000 state variables); this is also a tough mathematical problem: Non-linear, stiff, oscillating, poorly damped, discontinuous...

Power systems are becoming older and more intense. Thus, disturbances are inevitable and it is important to develop a powerful methodology to lessen the damages afterward. This paper proposes a new linear formulation based on an approximated version of AC power flow model to compromise between speed and accuracy of decision making process. In the proposed method, voltage and reactive power violations as well as transmission system overloads are alleviated by either or both of generation rescheduling and load shedding. The developed method adopts the line flows and square of voltage magnitudes as the problem state variables. Simulation results on the IEEE-RTS96 system reveal that the proposed method outperforms both the conventional and heuristic approaches from the execution time and the computational effort viewpoints while keeping the accuracy of the results.

The goal of this paper is to present a robust survivability strategy for the communication network in smart grids when communication failure happens because (1) communication failure is inevitable, (2) communication failure can impact smart grid performance. A communication failure can be temporary or permanent. A temporary failure is often caused by electromagnetic interference, storms, obstructions, and other temporary factors while a permanent failure is usually due to terminal or transmitter breakdown. A communication failure causes temporary or permanent unavailability of the communication link. Thus, the message broadcasted from the sending device may never reach the intended receiving device. A simple but realistic strategy will be proposed to model communication failure in a smart grid simulation test bed. Then, a solution to overcome the communication failure will be presented. The strategy will be tested on the modified IEEE 34 node test feeder.
