    Demand side management for residential consumers considering distribution system requirements
    (IEEE, 2021-04-11) Gomes, T. N; Nandasiri, N; Hettiarachchige Don, A. C. S; Aravinthan, V
    One of the focus areas of the smart-grid initiative is the residential level demand response. Recent surveys have analyzed price-responsive demand response optimization, mathematical modeling of demand response, responsive demand forecasting, and communication requirements. This paper identifies the benefit of the demand response programs available in the literature and presents an approach to incorporate utility-focused demand response benefits into distribution system operation. A two-stage demand-side management method is proposed using modified AC optimal power flow to maintain system requirements such as minimal deviations in nodal voltages and maintaining power factor. The results have been analyzed further by categorizing them into two areas; how the rescheduling has benefitted the consumers and the utility.

    Impact of non-functional requirements on the success of ubiquitous systems
    (IEEE, 2020-12-10) Sandeepani, S; Nawinna, D. P
    With the recent advancements of technology, Ubiquitous Systems have rapidly become popular all over the world. It is a new paradigm that focuses on smooth integration of technology in human environments enabling users to access information and functionality anytime and anywhere. Software development companies nowadays increasingly invest in the ubiquitous system development projects in order to stay competitive and survive in the IT Industry. Success of ubiquitous system development projects heavily depends on Nonfunctional user requirements. Identification of the nonfunctional requirements is challenging since it represents the quality attributes of the system and are not directly measurable. This quantitative research aims to evaluate the different types of non-functional requirements that significantly contribute to the success of ubiquitous system development projects. This study was based on the data collected from the software industry in Sri Lanka. The results of this study indicate that both the product-related and organizational-related nonfunctional requirements strongly affect the ubiquitous systems success. The findings provide insights to the vendors of ubiquitous system development companies in the software industry.
