Wave energy is an important renewable source of electricity that can be exploited. The reliability is an important issue for these energy converters due to the fact that they must be installed in harsh environments. The paper presents a reliability analysis of the linear generator type wave energy converters and shows the impact of the environment on the components of these devices.
Resiliency with respect to extreme events, such as a major hurricane, is considered one of the key features of smart distribution systems by the U.S. Department of Energy (DOE). In this paper, approaches to resilient distribution systems are reviewed and analyzed. Three important measures to enhance resiliency, i.e., utilization of microgrids, distribution automation (DA), and vulnerability analysis,...
With increasing penetration of plug-in hybrid electric vehicles (PHEVs), it is necessary to introduce a two-way interactive mechanism between PHEVs and the power system to improve system reliability and satisfy the PHEV charging requirements. To address these requirements, a bidirectional charging power control method, based on the time series model of PHEV charging, is developed. The control strategy...
As the end point of power delivery, a distribution system is directly connected with the consumers. It has complex structures and various operation modes which make the reliability even more important. However, the traditional FMEA cannot be applied to the complex distribution system which contains ring networks. Taking the capacity constraint of distribution system into consideration, this paper...
According to the character of certain missile power system zero-failure data, this paper presented Bayesian estimation method of zero-failure under entropy error loss. Firstly, we discussed Bayesian estimation of fixed-time censored data. Secondly, we obtained Bayesian estimation of zero-failure data by considering zero-failure data as the result of fixed-time censored test one by one. Using correlative...
This paper highlights the U.S. Department of Energy's Smart Grid R&D projects on dynamic optimization of distribution grid operations through integration of advanced sensing, communication, and control technologies. The progress and planned activities of the following programs are discussed: Renewable and Distributed Systems Integration demonstrations, microgrid developments, the Smart Grid Regional...
In the process of determining and investigating the reasonable operation mode of transformer, how to consider reliability and economic operation of transformer is a very important and necessary work. This dissertation chiefly studies the topic of accounting reliability and economic operation of transformer. Economy and reliability are the most two important index of Power System, but also contradictory...
The Ant Colony Algorithm is introduced to network planning for searching a group of network constructions within the constrains of distribution system. Several evaluating indexes such as power losses, mass loading ratio, H-1 certification are mentioned, and the weights of every factor are obtained by Analytical Hierarchy Process. Mathematical function is used to analyze every network, and the optimal...
Given a large and complex plant to operate, a real-time understanding of the networks and their situational reliability is important to operational decision support. This paper introduces using a unified model to help operators to minimize real-time problems, and also provide a mimic-real time play-back mechanism for system planners on how to upgrade the grid. Real-time simulation architecture is...
