Renewable energy sources (RES) will play a major role in future energy systems. Political RES goals are only defined in terms of targeted capacity or energy. This paper presents an approach to calculate the corresponding optimal location of RES generation. Potential areas for the expansion of the considered generation technologies (wind onshore and offshore, photovoltaics and concentrated solar power)...
This paper outlines the analysis of the concept in the implementation of distributed generation systems focused on the city of Bogotá. Different experiences of adoption of this type of generation, that could be located in various parts of the city, with special emphasis on the economic, environmental, and improved reliability of electricity supply, reported by different authors. Similarly, it also...
Smart grids are described as a tool to pursue a diverse set of political and environmental energy goals. Visions of smart grid implementation differ around the world, and roles in smart grids are not yet clearly defined and assigned. This paper systematically explores smart grid visions and pilot projects in selected countries representing different electricity system types: centralized versus decentralized...
This paper addresses the bidding problem faced by a virtual power plant (VPP) in a joint market of energy and spinning reserve service. The proposed bidding strategy is a non-equilibrium model based on the deterministic price-based unit commitment (PBUC) which takes the supply-demand balancing constraint and security constraints of VPP itself into account. The presented model creates a single operating...
Connection of Distributed Generation brings about a need to manage operation of distribution networks in a way that is more active. In order to allow for this change, DNOs need to devise strategies of how to manage generator outputs so to facilitate connection of renewable resources and maximize use of network assets. The paper will look into different techniques that allow for this type of operation...
This paper aims to investigate the impacts of the grid-connected PV generation systems regarding the intermittent nature of renewable generation, and the characterization of PV generation with regard to grid code compliance. The impacts described here include effects that have traditionally been considered a potential concern by the electricity industry, covering voltage, current and power effects...
Different concepts for the long term evolution of electricity networks have been proposed. Visions of large scale, continent-wide interconnections, local scale independent distribution network cells and networks integrating other forms of energy have emerged. The inclusion of new classes of network participants, e.g. prosumers, services providers, transportation applications, regulators and the increase...
One of the main barriers to the deployment of Demand Response (DR) and Distributed Generation (DG) is the ex-ante assessment of their benefits. The aim of this study is to develop a general framework to evaluate this potential using day-ahead historical market data. We observe that profitability of DR-based strategies can be linked to several market characteristics. Among them are the price levels...
The ADDRESS European project (active distribution networks with full integration of demand and distributed energy resources) aims to deliver a comprehensive commercial and technical framework for the development of ldquoactive demandrdquo in the smart grids of the future. It works towards enabling the active participation of domestic and small commercial consumers in power system markets and in the...
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...
Distributed Generation demonstrates to be able to significantly influence the electric power system, bringing considerable benefits to the quality of service and improving the energetic efficiency of the distribution network. In particular, in the last few years, Distributed Generation from renewable energy sources is considerably increased thanks to the many support policies promoted worldwide with...
