Self-organising energy demand allocation through canons of distributive justice in a microgrid

Abstract

The energy sector is being driven into a new era where considerable portions of electrical demand will be met through distributed energy resources (DERs). Microgrids have been suggested as a tool for integrating and managing DERs. In this context, we formulate the energy demand allocation problem in order to provide service to a given load. We then propose a dynamic method for agreeing and setting the rules to perform the allocation. The methodology is based on self-organisation and the concept of distributive justice which integrates different principles of fairness represented as legitimate claims. Legitimate claims are implemented as voting functions and are used to determine how the DER requests are satisfied. The method is tested by considering different configurations of DERs, mainly of the renewable type, and comparing them with other allocation methods. Results show that this self-organising allocation method provides a better balance amongst all the representations of justice, but also it is more robust for the external authorities that manipulate the allocation process.

Pulverization in Cyber-Physical Systems: Engineering the Self-Organizing Logic Separated from Deployment

“…Such macro-effects are often connected with the ability of the system to be resilient to environmental perturbations (ranging from human in-the-loop effects to faults in physical devices or communications-which are the norm in large-scale distributed systems), or to deal with changing functional/non-functional requirements that have to be satisfied in a wide variety of conditions. Relevant application of self-organization include: study of human social behavior [28], crowd tracking and steering [15], energy demand allocation [29], terrain exploration [30], smart camera coverage [31], task allocation of autonomous vehicles [32], and ICT resources coordination [33].…”

“…Furthermore, a proportional–integral (PI) controller with optimally computed PI‐parameters according to the state of complex demand has been introduced for maintaining the power density high in a flywheel‐based storage unit [20]. The concept of self‐organising energy demand allocation has been proposed in [21]. In the study, the steady‐state active power demand has been bifurcated among the available distributed energy resources.…”

Modelling enduring institutions: The complementarity of evolutionary and agent-based approaches

“…Monitoring can carry both physical costs, e.g., energy or CPU cycles, or opportunity costs where the time spent on monitoring is time lost carrying out other productive activities. This is true both in natural systems, such as irrigation systems (Weissing & Ostrom, 2000) and fisheries, and artificial systems such as community clouds (Khan, Freitag & Rodrigues, 2015) or community co-production energy systems (Torrent-Fontbona, López, Busquets & Pitt, 2016). Therefore, if self-interested agents are to be incentivised to monitor rule compliance then they need to be reimbursed for this cost somehow.…”
