Real-time retail price determination in smart grid from real-time load profiles

Abstract

Summary In a vertical organizational structure, component of a particular level has predetermined line of control from the objects of the management layer above it, but in horizontal organizational structure, objects of a layer are free to select the objects above them. The smart grid has a horizontal organizational structure compared to the power grid with vertical organization structure. This change in organizational structure always enabled independent operation of the components and demanding efficiency and profitability from these components. The distribution system of smart grid with a number of retailers in the market is relying on real‐time pricing to minimize the burden on consumers and to maximize its profit. In real‐time pricing, consumers are segmented based on their usage pattern and charged accordingly. In this paper, we formulated this complicated optimization problem and succeeded in computing real‐time selling prices for the consumers. For accurate and secure clustering, a new method is used, which is also well suitable for a big data environment like the smart grid. Consideration of price elasticity of consumers along with load profile, in the real‐time selling price determination, is the novelty of our paper. The optimization problem of profit maximization for retailers is solved using real‐time metering data collected from consumers in a smart grid pilot project in India. The results clearly show that real‐time prices for each class of consumers are according to their load profile.

A systematical analysis on the dynamic pricing strategies and optimization methods for energy trading in smart grids

“…Even though RTP is a real‐time pricing, which is seen as a positive point of view, 29,30 some researchers find that RTP, in some cases, is a two‐edged sword 31 . With the bidirectional communication between consumers and providers, numerous messages will be transmitted, leading to problems in the network such as messages loss, attacks, and delays of transmission.…”

Generating realistic building electrical load profiles through the Generative Adversarial Network (GAN)

“…1 Building electrical load profile is influenced by both physical and behavioral factors [1]. Building load profile analytics have wide applications, such as identification of unnecessary waste [2], load forecasting [3], customer segmentation and demand-side management [4], demand response planning and pricing [5], long-term resource planning, and renewable energy integration [6]. Therefore, collecting and analyzing load profiles plays a significant role in enhancing our understanding of how best to integrate buildings with a changing electric grid and to finally reduce building carbon footprints.…”

Real‐time pricing in smart community with constraint from the perspective of advertising game

“…Samimi constructed a comprehensive utility function for establishing a RTP scheme which still aimed to maximize social welfare . Joseph and Jasmin, considering the horizontal organizational structure of smart grid, designed an optimization problem to calculate the optimal real‐time prices for users . In addition to maximizing social welfare, the former research method focuses on the optimal management of household energy as well.…”

“…6 Joseph and Jasmin, considering the horizontal organizational structure of smart grid, designed an optimization problem to calculate the optimal real-time prices for users. 7 In addition to maximizing social welfare, the former research method focuses on the optimal management of household energy as well. For instance, Haider et al designed a dynamic residential load scheduling system that optimized the adaptive consumption pricing of household electric appliances.…”
