The importance of conducting adequacy assessments of standalone systems with integrated renewable generation sources is growing. In this work, the focus is placed on the reliability assessment of an isolated microgrid operating on renewable energy generated by wind turbines (WTs) and photovoltaic (PV) panels. Batteries for storage were included in the model because of their crucial role in the system’s feasibility. Additional micro-gas turbines (MGTs) served as conventional backup. The sequential Monte Carlo simulation (SMCS) method was used to carry out simulations of the system, which was modeled using Markov matrices. Input data, such as wind speed, solar irradiance, and ambient air temperature, were used to simulate the power outputs of the generators. These historical data were fitted into appropriate distributions to extract corresponding parameters when simulating essential key factors necessary to produce the renewable power generation models. The adequacy model of the MGTs was obtained by employing the two-state reliability model, which was also superimposed with the generation models of WTs, PV panels, and batteries. The IEEE Roy Billinton test system (RBTS) was used for demand modelling. Common reliability indices were computed, and the system availability margins were evaluated.

Model Case

In Japan most of the water distribution networks were constructed during the 1960s to 1970s. Since these pipelines were used for a long period, pipeline rehabilitation is necessary to maintain water supply. Although investment for pipeline rehabilitation has to be planned in terms of cost-effectiveness, no standard method has been established because pipelines were replaced on emergency and ad hoc basis in the past. In this paper, a method to determine the maintenance of the water supply on an optimal basis with a fixed budget for a water distribution network is proposed. Firstly, a method to quantify the benefits of pipeline rehabilitation is examined. Secondly, two models using Integer Programming and Monte Carlo simulation to maximize the benefits of pipeline rehabilitation with limited budget were considered, and they are applied to a model case and a case study. Based on these studies, it is concluded that the Monte Carlo simulation model to calculate the appropriate investment for the pipeline rehabilitation planning is both convenient and practical.
