Special Issue Information

Dear Colleagues,

Increasingly, the DSO will aggregate, apart from individual consumers and energy sources, as well as energy clusters (ECs) and other forms of energy communities (local balancing areas). The aim of an EC is to increase the level of local consumption, increase the share of RESs, facilitate balancing and maximize the economic benefits of the cluster members while maintaining certain standards of power quality. Most often, this comes down to achieving the highest possible level of self-sufficiency of a power supply from local sources. With the increase in the number of such ECs, it may turn out that a much greater benefit can be obtained by shaping the energy consumption/generation profile in these areas in accordance with a reference pattern. This will be a form of flexibility service that can be provided on commercial terms. Full energy self-sufficiency will be the exception. In order to implement such a scenario, it is necessary to obtain an appropriate level of observability (monitoring) and controllability (on the demand and supply side) within the highlighted ECs and their aggregation in order to shape the given total load profile. The latter will require effective communication between LBAs within the DT, monitoring their load profiles and using the possibility of changing them. The above considerations result in the so-called “digital twin” functionalities proposed by some ECs and DNOs in certain countries. These are mainly aimed at supporting the technical and economic activity of ECs and make the integration of different distributed energy resources (DERs) easier and more profitable.

The purpose of the proposed Special Issue is to present various contemporary DER technologies and their mutual integration and cooperation with public distribution networks. The Guest Editors are particularly interested in the following:

  • Presentations, to the greatest possible extent, of the practical effects of already functioning solutions.
  • Presentations of the widest possible set of energy sources and storage techniques, from traditional, solar, hydro, wind, geothermal and hydrogen energy, as well as waste heat utilization and energy harvesting, to efficient energy use and building automation. It is important to integrate several parallel operating sources and to control energy flows in order to achieve the assumed goals of energy communities.
  • Presentations of the widest possible range of energy problems that must be solved by energy communities, i.e., technical, organizational, business, social, economic problems, etc. We want to identify barriers to DER development and ways to overcome them.

At present, the Colombian government is faced with the challenge of guaranteeing access to energy services for all its inhabitants. However, as there are isolated populations or populations with difficult access to conventional electricity grids in the country, it is necessary to seek innovative and appropriate solutions to the conditions and needs of the so-called non-interconnected zones (NIZs), which allow the generation and consumption of energy in a local, efficient, and safe way for all users. For this reason, this research consisted of studying and proposing technological solutions that use distributed energy resources, making the most of the energy potential in each area, as a proposed solution to the problems faced by NIZs with energy shortages. As a result, a series of proposals with microgrids are obtained, taking advantage of their flexible characteristics and using NRES as energy sources, mitigating pollution and contributing to the energy transition sought by the Colombian government.

In the present article, the impacts that arise in electrical grids due to the integration of distributed energy resources (DER) are identified and analyzed, aiming to provide a basis from which the effects of these new technologies can be considered. To conduct this research, information was collected and analyzed, which was classified according to each of the impacts evidenced in the literature, such as technical, economic, social, environmental, sectoral, and political. Considering the classification of impacts by category, the corresponding advantages and disadvantages were highlighted, and based on this, a qualitative evaluation of the information found was conducted along with respective analyses. Thus, based on the development of this article, it can be concluded that DER influences many aspects, and according to the qualitative evaluation, clarity is provided regarding the contribution of each impact within electrical grids. It was found that, out of 100% of the impacts identified, those with the highest percentage of contribution are the technical impacts. Full article
