Residential Demand-Side Flexibility Provision Under a Multi-Level Segmented Tariff

This paper proposes a multi-level segmented tariff to encourage consumers to provide demand response using a battery. The aim of the tariff is to (i) properly reflect consumers’ contribution to the distribution grid cost while ensuring cost recovery for the distribution network operator and (ii) to provide consumers with a financial incentive to...

Fuzzy Logic-Based Online Energy Management System for Residential Microgrids

A fuzzy logic based online energy management system (FLEMS) is designed in this paper to achieve the optimal electricity cost in a residential Microgrid (MG). The proposed FLEMS is combined by a local energy price model (LEPM) and a fuzzy-logic strategy. The LEPM will preprocess the sampling data to estimate the electricity market and local MG...

Economic analysis of energy communities: Investment options and cost allocation

Energy communities play an important role in the energy transition to future clean and sustainable energy. The economic feasibility of an energy community is largely affected by its investment options: either a third party or households themselves can invest in distributed energy resources. Another common problem for energy communities is cost...

Cost Allocation in Integrated Community Energy Systems

With the growing concerns over energy depletion and environmental protection all over the world, more and more attention is being paid to energy transition towards renewable energy sources (RESs), energy efficiency improvement, and CO$_2$ emission reduction. Integrated community energy systems (ICESs) emerge in the development of local energy...

Communication efficient privacy-preserving distributed optimization using adaptive differential quantization

Privacy issues and communication cost are both major concerns in distributed optimization in networks. There is often a trade-off between them because the encryption methods used for privacy-preservation often require expensive communication overhead. To address these issues, we, in this paper, propose a quantization-based approach to achieve...

Nereus: Anonymous and Secure Ride-Hailing Service based on Private Smart Contracts

Security and privacy issues have become a major hindrance to the broad adoption of Ride-Hailing Services (RHSs). In this article, we introduce a new collusion attack initiated by the Ride-Hailing Service Provider (RHSP) and a driver that could easily link the real riders and their anonymous requests (credentials). Besides this attack,...

Cost allocation in integrated community energy systems — Performance assessment

Integrated community energy systems (ICESs) are a modern development of local energy systems by integrating distributed energy resources and local communities. Cost allocation is one of the key issues affecting the success of ICESs. Costs should be allocated to those who cause them, and benefits to those who make the investments. A well-designed...

Cost allocation in integrated community energy systems - A review

Integrated community energy systems (ICESs) emerged in the reform of local energy systems during the energy transition. Cost allocation within an ICES is one of the key issues determining the success of ICESs. The costs should be allocated fairly among the members of a local energy community. However, not much research has been directed...

Segmented energy tariff design for flattening load demand profile

In this paper, a segmented energy tariff design is proposed to incentivize consumers to flatten load demand. This energy tariff focuses on consumption levels instead of consumption periods. Energy storage is an effective strategy to help to maintain the imported energy from grid below the threshold without affecting the comfort of energy...

An opportunistic maintenance strategy for offshore wind turbine system considering optimal maintenance intervals of subsystems

Operation and maintenance (O&M) costs account for a large proportion of the total costs for offshore wind energy. Performing a reasonable maintenance strategy is an effective approach to reduce O&M costs and gain more profits. In this paper, an opportunistic maintenance strategy for offshore wind turbine systems considering...

Smart technology solutions for the NeTIRail-INFRA case study lines: Axle box acceleration and ultra-low cost smartphones

In this paper, we present preliminary results on the development of smart technology solutions for lower density railway lines. The goal is to reach a cost effective inspection and asset management to minimize maintenance<br/>interventions time/cost without dedicated inspection vehicles. The proposed methods include axle box acceleration...

Bambootopia--Multi-purpose bamboo process and utilization center

Cigondewah, as a growing industrial area in Bandung, is facing with serious ecological and societal dilemma because of rapid growth of violating textile industry. Polluted water and soil makes traditional food crop farming difficult to maintain, while industry land is biting up farmland, the last precious green space left in this area. To solve...

Effect of Spatial Variability on Maintenance and Repair Decisions for Concrete Structures

Due to the increasingly number of elder and deteriorating structures, maintenance is becoming a serious and more complex problem in most of the countries. A lot of studies have been carried out in this area for years. However, the fact that a lot of parameters show spatial random variability, which is linked with dependencies on temperature, w/c...
