[IEEE 2018 IEEE Power & Energy Society General Meeting (PESGM) - Portland, OR, USA (2018.8.5-2018.8.10)] 2018 IEEE Power & Energy Society General Meeting (PESGM) - An Innovative Methodology for Load and Generation Modelling in a Reliability Assessment with PV and Smart Meter Readings
摘要： With a paradigm shift from centralized to decentralized integration of distributed generation, particularly the photovoltaic (PV) systems made significant impacts on the reliability of power systems. The intermittency of PV and the stochastic nature of load results in a complex interaction of PV and load profiles, in a reliability assessment. In order to reduce the complexities of intermittent power generation interaction with smart meter customer consumptions, this paper presents an innovative methodology for the modeling of intermittent PV generation and smart meter readings in a reliability assessment in a power system. A case study was performed incorporating different scenarios of PV integrations with real-world smart meter load data, and climate projections weather in a UK environment. The results validate robustness of the proposed modeling framework for the reliability assessment in a power system with an accuracy of more than 99.5% and 97.5%, compared with actual generation and load profiles respectively.

Evaluation of the reliability of solar micro-grids in emerging markets – Issues and solutions
摘要： One of the most important technical features of a power system is its ability to deliver electricity reliably to the customers. Based on interviews with 12 energy service companies (ESCO) currently operating solar micro-grids in northern rural India, this study identified important factors related to technical design, customer behaviour and operations and management (O&M) that may result in contingencies in service. In addition, the study presents companies' innovative solutions to overcome these problems. Initially, the interview method allowed only a rough qualitative comparison of different reliability levels as the availability of comparable data was limited. We found that a more descriptive method for reliability assessment would create equally valuable information on renewable off-grid energy projects. We propose a simple framework for assessing reliability that highlights the particular features of off-grid areas in developing countries.
