    Effect of Environmental Parameters on Performance of Solar Photovoltaic System in Western India
    (IEEE, 2023-11) Mathur, Hitesh Datt
    This paper presents solar PV-based MG performance in relation to environmental parameters, such as temperature, wind speed, solar irradiance, and relative humidity. The MG system is installed at a commercial building in Pilani, Rajasthan, India, consisting of 77 monocrystalline PV solar panels. The analysis was performed with the real-time data collected from the weather monitoring system and the smart meters installed at the MG rooftop. The data collected comprised of outside temperature, wind speed, solar irradiance, and relative humidity. The correlation analyses were conducted between global horizontal irradiance (GHI) and temperature, wind speed, and relative humidity. Further, linear regression analysis was conducted to find the relative equation of temperature, wind speed, and relative humidity with the GHI. In order to provide a more precise relative equation between GHI and other parameters, non-linear regression analyses were also carried out. It was found that there exists a strong positive correlation between GHI and temperature, a positive correlation between GHI and wind speed, and a negative correlation between GHI and relative humidity. Ultimately, by estimating the power output using real data and comparing it to data obtained by the theoretical equation consisting of these weather parameters, the research paper concluded a high degree of correlation (0.817785).

    A critical and comparative review of energy management strategies for microgrids
    (Elsevier, 2022-12) Mathur, Hitesh Datt; Mishra, Puneet
    Energy management (EM) can be defined as the process of monitoring, planning, optimizing, and saving energy to obtain an energy-efficient system. A microgrid (MG) is considered a sustainable energy system but due to the uncertain nature of renewable energy resources (RERs) and electrical load, it requires an optimal and efficient energy management system (EMS). It is vital for optimal usage of distributed energy resources (DERs) in a secure and reliable way. This function of EMS is performed by an advanced decision-making approach which is present in it. In recent years, many researchers have focussed on the development of advanced EM strategies for MG to establish a self-sustained MG. Therefore, a comparative study is required to have a 360° view of the domain EM in MGs. In this regard, this article presents a critical and comparative analysis of the EM strategies developed for the MG’s optimal decision-making along with their demand response strategies. The broader classification of EMS based on supervisory control, operating time platform, and an approach for making a decision is discussed along with their limitations and solutions. To manage the dynamic and intermittent nature of RERs and load, different uncertainty handling and modeling approaches are summarized. A systematic review strategy consists of some tasks is adopted by the authors, for example (i) Extraction of research articles related to EM in MG; (ii) Filtering out the important articles to prepare a relevant research article database (iii) Critically analyzing the EM strategy developed in each article. In a broader perspective, this paper presents an up-to-date systematic analysis of EM strategies for MGs developed by various researchers. Finally, some recommendations and future research directions are also suggested. We hope that this article will help the readers to map the conceptual structure of this research field
