Abstract

Harmonic analysis is crucial to maintain the system power quality, especially in photovoltaic panels with load sharing scheme. Previous studies have discussed the impact of harmonic distortion on electric power systems in general, but there is still limited discussion on on-grid photovoltaic panel systems without the load-sharing scheme. Harmonic is a distortion phenomenon of current and voltage that is higher than fundamental frequency. The consumption of nonlinear loads contributes to the rising of harmonic distortion that has a bad impact on the system's power quality. This study aims to analyze and compare the levels of harmonic distortion on on-grid photovoltaic panels with a load-sharing scheme and evaluate the suitability with the IEEE 519-2014 standard. The result of this study shows that the Total Harmonic Distortion (THD) on the current   (THDi) in PLN"™s load and network exceeds the limit that is stipulated in IEEE 519-2014. THD current in PLN"™s loads and network is higher than the output current from the on-grid inverter because of the consumption of the nonlinear load. Meanwhile, Total Harmonic Distortion (THD) on the voltage (THDv) in the on-grid inverter, electric network, and load tends to be lower and still within the safe limit. This study is expected to support the implementation of an effective preventive strategy to reduce harmonic distortion on the performance of on-grid photovoltaic panels that will be optimum in the load-sharing scheme.

Abstract

This paper examines the performance of photovoltaic panels integrated into the electrical grid in a load-sharing scheme at Darool Ehsan Muhammadiyah Senior High School, Sragen. The study is part of Universitas Muhammadiyah Surakarta's community service program focused on renewable energy development in educational environments. Unlike previous studies relying on simulated data, this research uses real-time primary data from direct measurements of photovoltaic power production and grid electricity consumption over a specific period. The study"™s innovation lies in analyzing the photovoltaic system within a tropical climate-based load-sharing scheme and comparing energy usage when connected to photovoltaic panels versus when disconnected. It also evaluates the impact of reducing solar energy consumption from the grid. The collected data reveal an estimated daily load of 49.89 kWh, with PLN-supplied energy consistently exceeding inverter-supplied energy. Integration of photovoltaic panels into the grid reduces PLN electricity consumption by up to 30% during optimal sunlight periods, achieving an average system efficiency of 15%. This research offers valuable insights into the potential and challenges of implementing photovoltaic panels in educational settings, emphasizing the importance of climate considerations in system design and optimization. Future studies will focus on techno-economic evaluations of solar power installations and harmonic distortion (THD) analysis for larger-scale implementations.

Abstract

Tanaman anggrek merupakan salah satu tanaman hias yang ada di Indonesia dengan nilai estetika tinggi. Waktu proses pertumbuhan dan perkembangan tanaman akan membutuhkan sensor kelembaban tanah yang sangat optimal agar selalu seimbang. Keadaan tanah yang memiliki kadar air yang berlebihan akan menyebabkan pembusukan di bagian akar tumbuhan, sedangkan jika tanaman kekurangan kadar air juga membuat tanaman tidak dapat berbungan. Oleh karena itu, saat ini sudah ada pengembangan sistem penyiraman otomatis yang sudah menjadi topik penting di era modern ini. Penelitian ini bertujuan untuk menganalisis sistem penyiraman otomatis pada tanaman anggrek dengan menggunakan elektonika berbasis ESP32 dan sensor kelembaban yang menjadi mikrokontorel sekaligus konfigurasi terhadap aplikasi Bly melalui IoT. Metode penelitian yang digunakan adalah campuran yaitu dengan melibatkan 15 partisipan sebagai subjek penelitian, terdiri dari 10 orang yang diuji di dalam ruangan dan 10 orang di luar ruangan. Sistem ini dirancang untuk mendeteksi keembaban tanah dan mengatur penyiraman secara otomatis untuk menjaga kesehatan tanaman anggrek. Hasil penelitian menunjukkan sistem otomatis kelembaban tanah yang telah dirancang dengan menggunakan sensor capacitive soil moisture SKU:SEN0193, relay 5 volt, pompa air mini dc 12 volt, dan mikrokontroler NodeMCU ESP32 berbasis IoT hingga memperoleh hasil yang baik. Penelitian ini sudah melalui pengujian laboratorium dan lapangan, sistem ini juga sudah terbukti dengan respon lingkungan dalam mengoptimalkan penggunaan air berdasarkan kebutuhan tanaman.
