ModeMeter techniques for real-time small-signal stability monitoring continue to mature, and more and more phasor measurements are available in power systems. It has come to the stage to bring modal information into real-time power system operation. This paper proposes to establish a procedure for Modal Analysis for Grid Operations (MANGO). Complementary to PSS and other traditional modulation-based control, MANGO aims to provide suggestions such as redispatching generation for operators to mitigate low-frequency oscillations. Load would normally not be reduced except as a last resort. Different from modulation-based control, the MANGO procedure proactively maintains adequate damping at all times, rather than reacting to disturbances when they occur. The effect of operating points on small-signal stability is presented in this paper. Implementation with existing operating procedures is discussed. Several approaches for modal sensitivity estimation are investigated to associate modal damping and operating parameters. The effectiveness of the MANGO procedure is confirmed through simulation studies of several test systems.

This paper reports on the modeling and simulation of a stand-alone photovoltaic (PV) plant with maximum power point tracking (MPPT) feature and dedicated battery storage. The overall plant comprises the PV module, battery bank, MPPT module, controller, inverter and a resistive load. The load is supplied by both the PV and the battery bank. The fluctuations in the output of the PV module are controlled and held at maximum power output by the MPPT module. The battery controller is included to control the charging and discharging of the battery. The overall plant model is an integration of individual PV, MPPT, controller, inverter, battery and load models. The proposed model is used to determine the voltage, current and power at the maximum power point and then investigate the quality of voltage available at load terminals for different operating scenarios. The plant model has been found to be accurate to reflect satisfactorily the system behaviour for different loads as well as for different solar irradiance values. Response of the stand-alone plant to various changes in load demand as well as changes in solar irradiance and ambient temperature are presented along with the analysis of the simulated results.

The abundance of data available under the smart grid paradigm makes it possible for the system operator to enhance the situational awareness across the power network. More accurate data logging and reporting, especially in the newly adopted object oriented based communication protocols such as IEC 61850, allows for more efficient analysis and interpretation of the state of the network. This paper explores one of such applications that arise from employment of the standard IEC 61850 in substations. It is proposed here that the integrity of the data available from across the substation can be verified using the quality and validity data available from different devices and control/protection functions in the substation. A fuzzy cognitive map is used here that derives relationships and associations between various functions within the substation and determines a level of confidence on the data available. Although this scheme is developed for a substation in this paper, it can be equally well applied to other applications beyond substations and across the distribution automation domain.

Modern day power systems in the restructured environment have grown to a level of complexity that the use of automation has become imperative for secure operation and control. The volume of significant events that occur in a multi-area interconnected power system has become enormous to an extent that system operators need intelligent systems to support them in decision making. This paper presents an implementation of complex event processor (CEP) for processing high level power system events from the perspective of a multi-area system. The definition and modeling of basic and complex high level events is carried out and an event processing engine is employed to process data streams in real time to detect the occurrence of the events. Online real time data on the high voltage Indian national grid is used in this paper for driving the CEP system with the objective of detecting the occurrence of complex events. The methodology, implementation and results of the proposed CEP system are presented.

According to the requirement for a protection scheme based on synchronized phasor measurement in distribution networks with distributed generations, a RPR-based PPS distribution scheme was proposed. In this scheme, reserved control code group K28.6 in Ethernet physical coding layer is used as PPS positive edge transferred with preemptive priority in both ringlets of RPR. And a compensation algorithm is applied to balance out the propagation delay. And tolerance analysis and hardware design were presented in the paper. Simulation results indicate PPS distribution precision is up to nanoseconds level. The scheme enables the merger of both communication network and PPS synchronization network.

This paper presents an accurate track modeling for fault current on dc railways based on MATLAB/Simulink. With the introduction of skin effect of short-circuit current, the simulation of short-circuit fault based on MATLAB/Simulink is proposed. By comparing and investigating the waveforms of remote short-circuit current with and without skin effect, the paper pointed out the difference between these two currents. Moreover, the calculation of time constant proves the effectiveness of this result.

Locational marginal price (LMP) is a fundamental principle in the majority of electricity markets and is increasingly being employed at a number of ISO's such as PJM, california ISO, etc. It is essential to obtain the accurate value of LMPs. This paper presents an OPF formulation with a composite dynamic load models which is a composite of ZIP and induction motor loads. An improved locational marginal price (LMP) decomposition model for this formulation is also given, which can effectively decompose the LMP into three components. Case studies on a modified IEEE 30-bus and IEEE 118-bus system are reported to illustrate the impacts of composite load models on LMPs and its decomposition.

In this paper, a design and deployment of a Multi-Agent System (MAS) for a power system reconfiguration, restoration and load shedding is realized. The designed MAS is based on the human Immune System (IS) behavior in which different cells interact in order to heal the body. The proposed MAS is able to detect and isolate faults, reconfigure and restore power to the healthy loads and perform load shedding when necessary. The MAS system is implemented in microcontroller hardware and deployed on a power system testbed. The prototype is based on a shipboard power system and it is built for real time testing and development of Multi-agent systems. The simulation and experimental results show that the proposed MAS is very effective and promising in solving complex problems in power systems in general and specifically shipboard power systems.
