Multi-agent-based sharing power economy for a smart community

Abstract

Summary In this paper, a multi‐agent‐based locally administrated power distribution hub (PDH) for social welfare is proposed that optimizes energy consumption, allocation, and management of battery energy storage systems (ESSs) for a smart community. Initially, formulation regarding optimum selection of a power storage system for a home (in terms of storage capacity) is presented. Afterwards, the concept of sharing economy is inducted in the community by demonstrating PDH. PDH is composed of multiple small‐scale battery ESSs (each owned by community users), which are connected together to form a unified‐ESS. Proposed PDH offers a localized switching mechanism that takes decision of whether to buy electricity from utility or use unified‐ESS. This decision is based on the price of electricity at ‘time of use’ and ‘state of charge’ of unified‐ESS. In response to power use or share, electricity bills are created for individual smart homes by incrementing or decrementing respective submeters. There is no buying or selling of power from PDH; there is power sharing with the concept of ‘no profit, no loss’. The objective of the proposed PDH is to limit the purchase of electricity on ‘high priced’ hours from the utility. This not only benefits the utility at crucial hours but also provides effective use of power at the demand side. The proposed multi‐agent system depicts the concept of sharing power economy within a community. Finally, the proposed model is analyzed analytically, considering on‐peak, off‐peak, and mid‐level (mid‐peak) prices of a real‐time price signal during 24 h of a day. Results clearly show vital financial benefits of ‘sharing power economy’ for end users and efficient use of power within the smart community. Copyright © 2017 John Wiley & Sons, Ltd.

The Penetration of Renewable and Sustainable Energy in Asia: A State-of-the-Art Review on Net-Metering

“…Net-metering is a billing agreement between electricity utility provider and consumers that mandates the consumers to possess, operate and benefit from a distributed generation system (Solar PV or other generation system) meeting some or all of their energy consumption needs and getting financial paybacks for any surplus energy injected into the main grid [26]. The local generation consumed ( , , ), excess energy ( , , ), and the net consumption ( , , ) can be expressed as follows [27]:…”

Can Green Building Promote Pro-Environmental Behaviours? The Psychological Model and Design Strategy

“…Based on the collation of relevant literature, this article found that some scholars have discussed the promotion of green design strategies on environmental behaviour from different perspectives in previous studies. For example, Heinen et al found bicycle storage space, garbage sorting space, and outdoor design strategies related to functions such as space can promote users' green travel, garbage sorting and other environmental protection behaviours [11,22,23]; Zimring et al believe that the aesthetics of staircase design can affect the frequency of users using stairs [24,25]; Khashe et al discussed the role of self-regulating devices in green buildings to promote the energy-saving behaviour of users [11,26]; Choi et al believed that the intelligent feedbacks provided by energy and water metering devices in the building can effectively reduce energy and water consumption in buildings [27,28]; Qian et al are concerned about the impact of infrastructure and public transportation elements in the site on environmental protection behaviours such as green travel [29][30][31][32]; Batley et al believe that the purchase and use of renewable resources can better guide environmental behaviours, such as promoting users to use green electricity, using reclaimed water for washing behaviour, and using electric cars to replace traditional cars for travel [33][34][35]; Al-Fouzan et al emphasized the impact of parking space (including traditional car parking space and shared car parking space) on green travel behaviour [36,37]; Mahmood proposed an intelligent system to describe the concept of shared power resources within the community [38]. Based on the existing literature, this paper sorts out 7 green design categories and 17 green design strategies that can effectively guide users' environmental behaviours (see Table 2 for details).Some strategies can be found in the selected buildings and they provide a good base for the study of green building pro-environmental behaviours.…”
