Book excerpt: The large service interruptions of power supply in the transmission system have significant impact on modern society. The aim of the power system engineers is to prevent and mitigate such events with optimal decisions in design, planning, operation and maintenance. Due to the rapid growth in the power demand and competitive power market scenario, the transmission and distribution systems are frequently being operated under heavily loaded conditions. This tends to make failure of components more frequent in the power system necessitating large downtime to repair or replace the equipment. A majority of the service interruptions are happening due to lack of proper planning and operation of power system. Therefore, complete reliability assessment in generation, transmission and distribution systems is needed at the planning stage. The reliability assessment in smart grids is very much beneficial to the power operator and reduces the risk of grid failure due to failure of major components in power systems. This chapter is confined to composite power system reliability assessment. The composite power system combines both the generation and transmission systems' adequacy. The generation system in the composite power system includes both conventional and renewable sources. The composite power system reliability assessment is quite difficult due to the large number of equipment, interconnected network topology and uncertainties in generation capacity. The reliability assessment concentrates mainly on the use of probabilistic states of components in generation and transmission systems to evaluate the overall reliability. This analysis will result in a cost-effective system configuration to provide continuous power supply to the consumers at reasonable cost. The reliability level of the system is measured by the defined indices. One of these indices is the probability of average power availability at load bus. This reliability assessment mainly focuses on development of methods to evaluate the probability of average power availability at load buses for a specified system configuration. This chapter discusses the two main techniques called node elimination method and modified minimal cut set method.

Green (II.) and published by . This book was released on 2012 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The probabilistic reliability evaluation of power systems is a complex and highly dimensional problem that often requires a large amount of computational resources, particularly processing power and time. The complexity of this problem is only increasing with the advent of the smart grid and its accompanying technologies, such as plug-in hybrid electric vehicles (PHEVs). Such technologies, while they add convenience, intelligence, and reduce environmental impacts, also add dynamic and stochastic loads that challenge the current reliability and security of the power grid. One method that is often used to evaluate the reliability of power systems is Monte Carlo simulation (MCS). As the complexity and dimensionality of a power system grows, MCS requires more and more resources leading to longer computational times. Multiple methods have previously been developed that aid in reducing the computational resources necessary for MCS in order to achieve a more efficient and timely convergence while continuing to accurately assess the reliability of a given system. Examples include analytical state space decomposition, population based metaheuristic algorithms (PBMs), and the use of high performance computing (HPC). In order to address these issues, this dissertation is focused on improving the performance of algorithms used to examine the level of reliability in composite power systems through the use of computational intelligence (CI) and HPC, while also investigating the impact of PHEVs on the power grid at the composite and distribution levels. Contributions include the development and exploration of 3 variations of a new, hybrid algorithm called intelligent state space pruning (ISSP) that combines PBMs with non-sequential MCS in order to intelligently decompose, or prune, a given state space and improve computational efficiency, an evaluation of the use of latin hypercube sampling and low discrepancy sequences in place of MCS, the use of serial and parallel support vector machines for state classification when evaluating power system reliability using MCS, an investigation of the impact that PHEVs will have when integrated into the power grid at the distribution level, and the development of a new model for the probabilistic evaluation of composite system reliability that includes one of the key technologies in the smart grid, PHEVs.
Book Synopsis New Approaches to Composite Reliability Assessment of Smart Power Systems by : Badr Lami
Download or read book New Approaches to Composite Reliability Assessment of Smart Power Systems written by Badr Lami and published by . This book was released on 2017 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric power networks are complex systems because of their geographic spread and the consequent need for interconnections and integration of different components such as generators, transformers, lines, reactors, relays, and loads. Therefore, power utilities seek to ensure an acceptable degree of reliability in planning and operations, and accordingly, need information on component outages while satisfying the growing demand in order to ensure the availability of the system and prevent downtimes. Power systems of today are facing major challenges because of the rapid increase in penetration of energy resources (ERs) and plug-in electric vehicles (PEV). This thesis focuses on the evaluation of composite system reliability using direct probabilistic analysis techniques. The research presents the mathematical foundations, evaluation procedures, and reliability and risk indices associated with composite power system reliability evaluation using the minimal cut set calculations. The concept of minimal cut sets is applied to evaluate two sets of reliability and risk indices, system indices and nodal indices. System indices are essential for system planners and operators to determine the likelihood of interruption of supply, while nodal indices provide useful information on significant load points. The performance of the system under outage condition of generators, transmission lines, or both, is examined by conducting an appropriate power flow study. An optimal power flow (OPF) model is solved to find the system and nodal minimal cut sets and the associated indices. The thesis presents a novel composite system reliability based planning for ERs with clustering techniques based approaches to determine the optimal location, size and year of installation of ERs in the system. The K-means clustering and Fuzzy C-means clustering techniques are applied to the set of reliability indices, Load Not Served per Interruption (LNSI), which are determined using nodal minimal cut sets. The nodal minimal cut sets are obtained using an OPF based approach. Once the optimal sizes and locations of ERs are obtained, the earliest year of their penetration into the system is determined using an adequacy check algorithm. The thesis further presents a novel method to detect the critical components of composite power systems under steady-state conditions and short-term operations in order to help planners make economic decisions on new investments in generation capacities and transmission lines upgrades, and also to help operators maintain the delivery of electricity during system failure and disturbance events. Each component is ranked based on minimal cut set outage probability and the consequent loss of load arising from the outages of components belonging to a minimal cut set. Finally, the thesis presents a novel framework to evaluate the impact of PEV charging loads on composite power system reliability. A Smart-OPF model combined with a minimum cut set approach is proposed to evaluate the system reliability indices. Demand response (DR) is included in the proposed procedure and its impact on system reliability indices is studied. The procedure to determine the critical components of the power system in the presence of PEV loads and DR is also proposed.

Book Synopsis Reliability Evaluation of Composite Power Systems Including the Effects of Hurricanes by : Yong Liu
Download or read book Reliability Evaluation of Composite Power Systems Including the Effects of Hurricanes written by Yong Liu and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Adverse weather such as hurricanes can significantly affect the reliability of composite power systems. Predicting the impact of hurricanes can help utilities for better preparedness and make appropriate restoration arrangements. In this dissertation, the impact of hurricanes on the reliability of composite power systems is investigated. Firstly, the impact of adverse weather on the long-term reliability of composite power systems is investigated by using Markov cut-set method. The Algorithms for the implementation is developed. Here, two-state weather model is used. An algorithm for sequential simulation is also developed to achieve the same goal. The results obtained by using the two methods are compared. The comparison shows that the analytical method can obtain comparable results and meantime it can be faster than the simulation method. Secondly, the impact of hurricanes on the short-term reliability of composite power systems is investigated. A fuzzy inference system is used to assess the failure rate increment of system components. Here, different methods are used to build two types of fuzzy inference systems. Considering the fact that hurricanes usually last only a few days, short-term minimal cut-set method is proposed to compute the time-specific system and nodal reliability indices of composite power systems. The implementation demonstrates that the proposed methodology is effective and efficient and is flexible in its applications. Thirdly, the impact of hurricanes on the short-term reliability of composite power systems including common-cause failures is investigated. Here, two methods are proposed to archive this goal. One of them uses a Bayesian network to alleviate the dimensionality problem of conditional probability method. Another method extends minimal cut-set method to accommodate common-cause failures. The implementation results obtained by using the two methods are compared and their discrepancy is analyzed. Finally, the proposed methods in this dissertation are also applicable to other applications in power systems.
