Continuous connection of Distributed Energy Resources (DER) technology on a “fit and forget” basis may lead to inefficiently low utilization of generation and network assets. In order to mitigate this effect, a reappraisal of the technical, regulatory, and commercial frameworks that shape decisions on future network design, investment, operation, and pricing are required. The transition of distribution...
In the energy management of a small power system, the scheduling of the generation units is a crucial problem for which adequate methodologies can maximize the performance of the energy supply. This paper proposes an innovative methodology for distributed energy resources management. The optimal operation of distributed generation, demand response and storage resources is formulated as a mixed-integer...
This paper presents an intelligent approach for managing reactive power from a group of distributed generators (DG) connected to low voltage (LV) bus. The objective is to minimize active power losses and keep the voltage profiles in the network within specified limit. This approach finds optimal DG reactive power and optimal tap changer position for main substation transformer every fifteen minutes...
Despite growing research interest in evaluating optimal decisions for a load-serving entity (LSE), the literature contains only a few studies that deal with the task of determining strategic power purchases for a distribution company, a retailer, or even a large customer. The scope of this paper is limited to a discussion of the incorporation of distributed generation (DG) units into a company's operation,...
Distributed generation is not yet considered to participate in balance management in power systems. Low marginal costs and poor predictability make them less attractive for this application. However, further integration of distributed generation will make participation in balance management a necessity both for down regulation as well as up regulation. The potential of different distributed generators...
Steadily increasing needs for electrical power, progress in power deregulation, tight construction constraints on new high voltage lines for long distance power transmission, and global environmental concerns have created increased interest in alternative energy (AE) generation. Hybrid combination of AE sources can significantly improve their reliability and better deliver power to customer loads...
This paper analyses sustainability transitions in the electricity sector. Using a Multi Level Perspective on transitions, three transition pathways are briefly elaborated and indications for the consequences for the infrastructure are given. The transformation pathway is characterised by a further hybridisation of the infrastructure; in the reconfiguration pathway, internationalisation and scale increase...
