Abstract

Saat ini di Kecamatan Ngadu Ngala, Kabupaten Sumba Timur sudah ada PLTD dengan kapasitas daya sebesar 2x25 kVA dan listrik dapat dinikmati selama 6 jam per hari. Pada studi ini dilakukan perencanaan untuk kebutuhan listrik 10 tahun kedepan dengan pola penyediaan menyala selama 6 jam dan selama 24 jam per hari. Alternatif yang digunakan adalah konfigurasi PLTD, konfgurasi PLTS hybrid dengan PLTD dan konfigurasi PLTS. Berdasarkan analisa data yang dilakukan menggunakan HOMER untuk perencanaan kebutuhan listrik 10 tahun kedepan dengan pola penyalaan selama 6 jam per hari konfigurasi terbaik adalah PLTS hybrid dengan PLTD dengan kapasitas PLTS sebesar 4 kWp, PLTD sebesar 26 kW dan memiliki biaya energi sebesar USD 0,368 per kWh sedangkan untuk pola penyalaan selama 24 jam per hari konfigurasi terbaik adalah PLTS hybrid dengan PLTD dengan kapasitas PLTS sebesar 200 kWp, PLTD sebesar 72 kW dan memiliki biaya energi sebesar USD 0,281 per kWh.

Abstract

Sistem pembangkit listrik tenaga surya On-Grid skala kecil (panel surya) memiliki potensi besar untuk memenuhi kebutuhan energi listrik di rumah tinggal. Namun, ada beberapa kendala yaitu ada daerah yang tidak menyediakan pemasangan meter ekspor – impor dan biaya pemasangan meter ekspor – impor yang tidak murah. Salah satu alternatif solusi untuk permasalahan ini adalah dengan menggunakan Grid Tie Inverter with Limiter (GTIL) untuk mencegah energi berlebih masuk ke jaringan listrik. Pada saat energi yang dihasilkan panel surya lebih besar dari beban terpasang, maka GTIL membatasi daya yang dihasilkan oleh panel surya menjadi sesuai dengan kapasitas beban terpasang. Makalah ini membahas pemanfaatan GTIL dan analisa rugi daya dari penggunaan sistem limiter. Dari hasil analisa, diketahui bahwa sistem limiter bekerja dengan melakukan pergerseran titik kerja panel surya sesuai dengan daya total beban terpasang, dan rugi daya dapat dikurangi dengan melakukan alokasi daya yang dihasilkan ke baterai.

Abstract

This study presents clustering-based assessments of solar attributes for locating potential solar photovoltaic (PV) power plant sites using k-means and density-based spatial clustering of applications with noise (DBSCAN) by examining the yearly average single-attribute and three-attribute clustering on a dataset of long-term hourly-based direct and diffuse irradiation, ambient temperature, and solar PV power output from 2005 to 2022. Three-attribute clustering enables stakeholders to better understand the characteristics of a cluster by collectively identifying three solar attributes and the magnitude of each attribute in an area or cluster. The presence of this information, which constitutes the clusters, suggests that these attributes have different effects on solar PV output power in different clusters. Although k-means is an effective method for investigating potential locations for PV power plant placements, DBSCAN offers users an alternative method for accomplishing a similar goal. In the case of three-attribute clustering of direct irradiation with k-means and DBSCAN, the 18-year mean value of clusters with the highest yearly average value is achieved at very similar values of 0.305 kW/m2 and 0.310 kW/m2, respectively. It turns out that only six years of direct irradiation had an annual mean value of less than 0.305 kW/m2. This finding implies that in the long run, the solar resources in terms of direct irradiation will typically surpass 0.3 kW/m2/MW installed capacity over all areas suitable for PV power plants. While focusing on the Java-Bali region, Indonesia, the findings, and methods appear to be of broader interest to policymakers, particularly in developing countries where solar PV is considered an option for sustainable energy generation.

Abstract

Sustainable energy transitions in developing countries are critical for balancing economic growth and environmental sustainability. Transitioning to renewable energy sources alleviates energy poverty and reduces reliance on fossil fuels. Information and communication technology (ICT) plays an important role in advancing the energy transition and achieving low-carbon energy utilization by facilitating the transition of power sectors to renewable energy sources. This paper provides an overview of the role of ICT in achieving sustainable energy transition in developing countries and jurisdictions. It emphasises the significance of SDG 7 and other sustainable energy transition indices for energy access and transition, as well as presenting their status and progress in various regions, including developing countries. This paper also discusses several types of available ICT tools and methods that enable digitalization in the power sector, such as smart grids, smart metres, energy management systems, Internet of Things (IoT) for energy, and renewable energy monitoring systems, as well as the opportunities and challenges of incorporating ICT into the context of developing countries' sustainable power sector.

Abstract

Many developing countries, including Indonesia, are progressing poorly in residential rooftop photovoltaic (PV) adoption, including on-grid systems. On the customer side, the decision to implement on-grid rooftop PV or rely only on power from the utility grid has often been made without appropriate knowledge of techno-economic considerations. This includes the impression of high system costs. This paper introduces KawanSurya: PV calculator, a solar rooftop PV techno-economic application for Android mobile phones, designed to help residential customers assess the potential of installing on-grid rooftop PV systems. The tool allows users to select a specific geographic location, calculate daily load profiles, and determine available roof areas. It uses irradiance data from the PVGIS API and HOMER’s solar PV output equation to determine hourly PV output power. Simulation results for a typical 2,200 VA household show a payback period of 9.44 years or beyond, significantly influenced by electrical load profiles and bill reduction factors. A 65% bill reduction factor and similar load profile prolong the payback period, while a 0% billing reduction factor or uncompensated electricity sales may exceed the project’s lifetime.

Abstract

The persistent reliance on fossil fuels for energy will yield enduring adverse effects on the tourism sector, particularly the hotel industry. Wind energy represents a renewable electricity source that can facilitate the transition of small-scale hotels to clean energy. The main objective of this research is to propose a methodology for evaluating the potential of wind energy to support sustainable tourism in developing nations, specifically in fulfilling the electricity requirements of small hotels. This study aims to assess and compare the potential contribution of small wind turbines to hotel energy demand by modelling a historical hourly wind dataset spanning ten years (2011-2020) and forecasting a portion of the dataset. This research selected three sites in Indonesia exhibiting varying wind energy potentials: Tepus District in Gunung Kidul Regency, Losari Beach in Makassar City, and Nusa Penida Island in Bali. This study utilises multiple linear regression to examine the impact of external variables on wind speed, and it applies Seasonal Autoregressive Integrated Moving Average (SARIMA) and Holt-Winters Exponential Smoothing (HWES) for wind speed forecasting in these three locations. The hourly and daily interval datasets analysis reveals a weak correlation between external factors and wind speed, with the HWES method identified as the most appropriate approach for modelling and forecasting wind speed, surpassing the SARIMA model by 0.309 RMSE. Forecasting results indicate that a 30-kW wind turbine could supply 8.8 - 35.3% of a small hotel's electricity consumption, depending upon the occupancy rate.
