In this article, an automated statistical test approach for the systematic quality assurance of component-based systems is presented. From state-based component models a compact interaction test model is constructed, which describes component interactions and interaction sequences. The model is annotated with an interaction profile to facilitate the generation of representative test cases and t...

This article proposes a novel approach to quantitative software reliability assessment ensuring high interplay coverage for software components and decentralized (sub-)systems. The generation of adequate test cases is based on the measurement of their operational representativeness, stochastic independence and interaction coverage. The underlying multi-objective optimization problem is solved b...

Provide a methodology to simulate the financial response of multiple participants of a two sided auction including reliability, substitutes, and other ancillary services. Methodology would provide justification for generation and customer equipment as required for system expansion with an optimal portfolio of equipment to maximize system operation at a specified level of reliability. Research S...

Recent advancements in photovoltaic (PV) system technologies have decreased their investment cost and enabled the construction of large PV farms for bulk power generations. The output power of PV farms is aaected by both failure of composed components and solar radiation variability. These two factors cause the output power of PV farms be random and diierent from that of conventional units. The...

Existing input domain-based reliability models do not account for software reliability growth, because they do not consider fault corrections. This paper proposes an input domain-based reliability growth model with fault correction history being taken into account. Both partition and random testing can be used to generate input cases for test runs. It is generally considered in the model that i...

This paper presents an algorithm for the microgrid planning as an alternative to the co-optimization of generation and transmission expansion planning in electric power systems. The integration of microgrids in distribution systems will offer a decentralized control of local resources for satisfying the network reliability and the power quality required by local loads. The objective in this pap...

Today’s integrated circuits are becoming more susceptible to faults due to effects caused by aggressive technology scaling. However, to meet the ever-increasing reliability requirements of safety-related applications, the system has to function correctly even in the presence of faults. This leads to the challenging problem of fault-tolerant system design. Here, the goal is to meet the required ...

In this paper we develop a possible notion of shortterm value-based reliability for operating an electric power network. As the electric power industry goes through the restructuring process, the operation based on the value-based reliability may be more appropriate than based on the traditional (N1) security criteria. The value-based reliability requires a framework where the factors to be con...

Low-CO2-emission wind generation can alleviate the world energy crisis, but intermittent wind generation influences the reliability of power systems. Energy storage might smooth the wind power fluctuations and effectively improve system reliability. The contribution of energy storage to system reliability cannot be comprehensively assessed by the installed capacity of energy storage. The primar...
