Abstract

Determining the energy potential of biomass is the first step in selecting the most suitable and efficient energy conversion technology based on regional characteristics. The approach to estimating and determining biomass potential generally uses geospatial technology related to collecting and processing data about mapping an area. Unfortunately, this method is inadequate for simulating the interaction between variables, nor can it provide accurate predictions for the biomass supply chain. As a result, the results obtained from this method tend to be biased and macro, particularly in regions experiencing rapid land-use development. In this paper, the author has developed a clustering methodology with a fuzzy c-means (FCM) algorithm to determine biomass energy potential based on regional characteristics to produce data clusters with high accuracy. Grouping the characteristics of clustering-based areas involves grouping physical or abstract objects into classes or similar objects.

Abstract

The Timor system is one of the large systems in the East Nusa Tenggara region. Based on the general plan for electricity supply for 2021-2030, there is a plan to interconnect a 2x11 MW wind power plant. The addition of wind power plants will pose a considerable threat to the system due to the intermittency nature of renewable energy plants. Therefore, a comprehensive grid impact study is needed to convince network managers that adding wind farms will not cause disruptions to the system either locally or in general and is expected to strengthen the electricity system. The power flow simulation results, installing a 2x11 MW wind farm on the Timor system can improve voltage quality and reduce losses on both 70 and 150 kV systems. For transient stability, the frequency value on the Timor system still meets the grid code requirements. In addition, the simulation results of the intermittency impact of the wind power plant output show that the Timor system is still in a stable condition. The stability of the rotor angle of the existing power plant when the transient stability simulation is carried out shows that it is still in a balanced condition.

Abstract

Analisis multivariat pada profil beban listrik adalah pendekatan yang penting untuk memahami pola penggunaan energi secara holistik dan mendalam. Dengan mengintegrasikan berbagai faktor yang mempengaruhi konsumsi energi listrik. Studi ini bertujuan untuk melakukan profilisasi beban listrik menggunakan metode analisis komponen utama (Principal Component Analysis, PCA) dan algoritma K-Means, serta mengevaluasi pemodelan dengan Regresi Linier Berganda dan menganalisis korelasi antara variabel-variabel terkait. Data beban listrik dari suatu wilayah tertentu dikumpulkan dan diolah menggunakan teknik PCA untuk mengidentifikasi pola utama dalam distribusi beban. Selanjutnya, algoritma K-Means digunakan untuk mengelompokkan pola-pola tersebut menjadi kategori yang lebih terdefinisi. Model Regresi Linier Berganda kemudian diterapkan untuk mengevaluasi hubungan antara variabel-variabel beban listrik dengan faktor-faktor yang memengaruhinya. Analisis korelasi digunakan untuk mengeksplorasi keterkaitan antara variabel beban listrik dan faktor-faktor lingkungan atau ekonomi yang dapat memengaruhi konsumsi energi. Hasil dari penelitian ini variabel PDRB,Jumlah Rumah tangga, beban listrik pada sektor bisnis dan perumahan memiliki korelasi yang dapat dikategorikan kuat yang melebihi nilai koefisien korelasi diangka 0,6. Reduksi duabelas variabel menggunakan PCA yang mempengaruhi konsumsi energi listrik menjadi empat variabel utama yaitu PDRB,Jumlah Rumah tangga, beban listrik pada sektor bisnis dan perumahan. Pemodelan yang menggunakan metode PCA mempunyai hasil yang baik dengan nilai RMSE 1.09
