Abstract

In this work, a historical data based battery management system (BMS) was successfully developed and implemented using an embedded system for condition monitoring of a battery energy storage system in a smart microgrid. The performance was assessed for 28 days of operating time with a one-minute sampling time. The historical data showed that the maximum temperature increment and the maximum temperature difference between the batteries were 4.5 °C and 2.8 °C. One of the batteries had a high voltage rate of change, i.e. above 3.0 V/min, and its temperature rate of change was very sensitive, even at low voltage rate of changes. This phenomenon tends to indicate problems that may deplete the battery energy storage system’s total capacity. The primary findings of this study are that the voltage and temperature rates of change of individual batteries in real operating conditions can be used to diagnose and foresee imminent failure, and in the event of a failure occurring the root cause of the problem can be found by using the historical data based BMS. To ensure further safety and reliability of acceptable practical operating conditions, rate of change limits are proposed based on battery characteristics for temperatures below 0.5 °C/min and voltages below 3.0 V/min.

Abstract

Every building has certain electricity consumption patterns that depend on its usage. Building electricity budget planning requires a consumption forecast to determine the baseline electricity load and to support energy management decisions. In this study, an algorithm to model building electricity consumption was developed. The algorithm is based on the support vector regression (SVR) method. Data of electricity consumption from the past five years from a selected building object in ITB campus were used. The dataset unexpectedly exhibited a large number of anomalous points. Therefore, a tolerance limit of hourly average energy consumption was defined to obtain good quality training data. Various tolerance limits were investigated, that is 15% (Type 1), 30% (Type 2), and 0% (Type 0). The optimal model was selected based on the criteria of mean absolute percentage error (MAPE) < 20% and root mean square error (RMSE) < 10 kWh. Type 1 data was selected based on its performance compared to the other two. In a real implementation, the model yielded a MAPE value of 14.79% and an RMSE value of 7.48 kWh when predicting weekly electricity consumption. Therefore, the Type 1 data-based model could satisfactorily forecast building electricity consumption.

Abstract

AbstrakPemantauan konsumsi energi merupakan langkah manajemen energi yang efektif dalam penghematan energi untuk jangka panjang. Pada penelitian ini dilakukan pengembangan pada perangkat keras dari sistem pemantauan untuk sub-metering. Sub-metering yang dilakukan membagi pengukuran menjadi tiga masukan arus: stop kontak, air conditioner, dan penerangan ambient, yang diakuisisi dengan menggunakan sensor arus non-invasive SCT-013-030. Data yang diakuisisi kemudian diolah oleh Arduino UNO, disimpan ke SD Card menggunakan Arduino Ethernet Shield dalam keadaan offline untuk kemudian dibuat model hariannya dari hasil pengukuran sebagai referensi pengukuran real-time.Untuk memverifikasi model harian dari hasil pengukuran harian pengguna energi, dibuat suatu pemodelan konsumsi listrik base-line yang diasumsikan hemat. Tampilan real-time yang nantinya dibandingkan dengan pemodelan harian diunggah ke jaringan Ethernet dengan menggunakan Arduino Ethernet Shield dalam keadaan online. Sedangkan perangkat lunak yang digunakan untuk menampilkan di halaman web adalah RGraph, sebuah perpustakaan grafik bebas pakai berbasis javascript.Pada akhirnya, penelitian ini dapat melahirkan rekomendasi-rekomendasi penghematan yang spesifik. Hasil penelitian ini juga menunjukkan bahwa sensitivitas sensor arus dan signal conditioner yang digunakan adalah sebesar 7 Ampere/bitdengan tingkat presisi yang baik. Sedangkan resolusi, yakni perubahan 1 bit pada signal conditioner terjadi apabila ada perubahan setiap 0, 15 Ampere pada sensor arus.Kata Kunci: Pemantauan Energi, Sub-metering, SCT-013-030, Arduino, Arduino Ethernet Shield, Real-time, RGraph

Abstract

From the electricity system point of view, smart buildings can be seen as an integration of a microgrid electricity network that connects solar PV, storage system, and building load distribution. The operation condition of the microgrid needs to be evaluated and optimized to obtain efficient and reliable performance. This contribution presents an energy management modeling for the microgrid optimization process in a smart building system. The energy sources connected to the microgrid are solar PV, battery storage system, and the PLN (utility) grid. Combinations of load scenarios are evaluated, which consists of building a lighting system, water pump, dan HVAC system. The optimization goal is to find the optimal estimation of Self Consumption (SC) and Self Sufficiency (SS) values. A simulation result before the optimization shows that the system is operating with SC of 63.2% and SS of 96.32%. After the optimization, the values become SC = 84.68% and SS = 83.27%. Therefore, the amount of energy sourced from the Solar PV system is increased and the microgrid is working more optimally.

Abstract

Penelitian ini dilakukan untuk mendemonstrasikan suatu metode optimisasi perletakan dan penjadwalan sistem pencahayaan dalam ruang, untuk meningkatkan eksitansi rata-rata permukaan dalam ruang (MRSE) dan metrik otonomi cahaya alami (DA), serta menurunkan konsumsi energi pencahayaan tahunan. Dua ruang laboratorium uji beton yang berlokasi di Balai Besar Bahan dan Barang Teknik, Bandung, Indonesia, dipilih sebagai studi kasus. Optimisasi pencahayaan alami dilakukan dengan menghilangkan langit-langit gantung laboratorium, memenuhi target MRSE200/50% dan DA200/50% sepenuhnya di ruang timur, tetapi hanya sebagian di ruang barat. Optimisasi pencahayaan elektrik dilakukan untuk memenuhi target yang tersisa dengan menentukan posisi luminer menggunakan algoritme genetik (GA) dalam simulasi Grasshopper dan Octopus. Posisi yang dihasilkan memenuhi seluruh tujuan di sebagian besar zona. Penjadwalan kontrol pencahayaan kemudian diusulkan berdasarkan profil DA dan MRSE dalam ruang. Sistem terintegrasi yang diusulkan menghasilkan konsumsi energi pencahayaan tahunan sebesar 9,9 kWh/m2/tahun untuk ruang barat dan 1,0 kWh/m2/tahun untuk ruang timur. Penelitian ini dilakukan untuk mendemonstrasikan suatu metode optimisasi perletakan dan penjadwalan sistem pencahayaan dalam ruang, untuk meningkatkan eksitansi rata-rata permukaan dalam ruang (MRSE) dan metrik otonomi cahaya alami (DA), serta menurunkan konsumsi energi pencahayaan tahunan.

Abstract

Electrical energy is one of the basic human needs in carrying out various activities or daily activities, especially in office buildings such as office buildings of state higher education institutions, namely the Sumatra Institute of Technology (ITERA). Office buildings are the third highest consumer of electrical energy after shopping centers and hotels. The high demand for electrical energy requires the user sector to make efficiency in energy use. Before making efficiency, it is necessary to know the profile of electrical energy consumption including energy consumption intensity (ECI) and significant energy users. Therefore, in this study, an analysis of electrical energy consumption in each ITERA office building was carried out, through observation and interviews according to SNI / ISO 50002: 2018 energy audit procedures. The results obtained show that the total energy use of the 6 largest buildings (A, B, C, D, E, and F) in May 2023 is 144768 kWh and from the calculation of the ECI value is in the very efficient category (7.44 kWh/m2/month). From 6 existing buildings, there are 3 buildings that are very efficient, 1 building is efficient, and 2 buildings are quite efficient. Then, significant energy users were found by 83% in building C AC. Recommendations for saving energy in the effort of energy conservation and efficiency that can be done include, making changes in habits / patterns of use of electrical energy user equipment, especially in air conditioners and dispensers, so as to save electricity 2-21%, and retrofitting refrigerant AC types of split ducts and cassettes that still use R-22 with MC-22 which can save electricity 15-25%.
