Developing Novel Technologies and Services for Intelligent Low Voltage Electricity Grids: Cost–Benefit Analysis and Policy Implications

Abstract

The paper presents a set of prototype smart grid technologies and services and validates the economic viability of the proposed solution using cost–benefit analysis (CBA). The study considered the EU-funded project called RESOLVD and implemented the technologies and services in a real-life pilot. the technologies and services on the EU-funded H2020. The paper focuses on the analysis of technological solutions which enhance the operational efficiency and the hosting capacity of low-voltage electricity distribution grids. The solutions provided better integration of a hybrid battery storage system, with the grid interfacing power electronics, smart gateways for the interconnection of assets at the grid edge, and sensors enhancing infrastructure observability and control. The result from the CBA indicates the economic viability of the project, high scalability, and replicability. The economic benefits were realized with the breakeven value of eight secondary substations (SS) and 16 feeders. The scenario test on the DSO’s willingness to pay for the software as a service (SaaS) revealed that the payback period can further be reduced by almost half with a higher internal rate of return (IRR) and net present value (NPV). Both the CBA and scenario tests showed RESOLVD solution can become more economically viable when deployed in largescale. Moreover, the CBA results provide evidence to the energy policy by allowing DSOs to consider both CAPEX and OPEX for better investment decisions. Further, the paper proposes an alternative business approach that shifts from grid reinforcement to service provision. The paper also discusses the research implications on energy policy and business.

Analisis Kelayakan Investasi Pembelian Armada Trailer Truck pada Distributor Baja X

“…Kemudian disusul implikasi kebijakan dengan nilai 2 (11%). Beberapa penelitian menggunakan variabel endogen implikasi kebijakan untuk melihat apakah penerapan teknologi dan layanan dalam uji coba di kehidupan nyata akan berdampak pada biaya-manfaat dan implikasi kebijakan pada jaringan listrik tegangan rendah seperti seperti yang dilakukan oleh Belay AM dkk, 2022 (Belay, et al, 2022). Kemudian, penelitian lain yang hanya fokus pada kelayakan finansial ditulis oleh Poh Ying Hoo dkk pada tahun 2018 dengan fokus penerapan injeksi biometana pada jaringan distribusi gas alam dengan tarif FiT di Malaysia (Hoo, Hashim, & Ho, 2018).…”

“…Kemudian perusahaan yang akan menjadi objek penelitian adalah Distributor X yang bergerak di bidang distribusi baja yang berbasis di Indonesia (negara berkembang) dengan investasi yang akan dilakukan adalah penambahan jumlah truk trailer berkapasitas 60 ton. Dalam melakukan analisis kelayakan investasi, penelitian ini mengikuti beberapa metode pendahulu seperti pada (Belay, et al, 2022)…”

Design optimization of dual active bridge converter

“…Owing to the inherent features of IBDC converters, they find extensive applications across various domains, as illustrated in Figure 1.1. As shown in Figure 1.1, one notable application involves the interconnection of distinct DC networks or integrating diverse energy storage systems, encompassing battery technologies, fuel cells, and supercapacitors [15,16]. Furthermore, IBDC converters constitute a critical component of the solid-state transformer (SST) concept.…”
