Special Issue Information

Dear Colleagues,

With the growing concerns regarding the increase of energy demand and environmental problems, the efficient use of energy resources is a key topic for enhancing the sustainability of energy supply. In such a context, local energy communities represent a promising solution for the decarbonization of the energy supply by promoting the usage of local renewable energy sources and activating local demand response.

Local energy communities may involve distributed energy resources (DER), including renewables, storage devices, and controllable loads, which, operating in a controlled and coordinated way, can offer several benefits to utilities and final users, such as improved energy efficiency, reduction in energy consumption and environmental impacts, and an increase in reliability and resilience of the energy system as a whole. In order to achieve these benefits and foster the effective penetration of this new energy paradigm, planning, operation, and control aspects are crucial.

The objective of this Special Issue is to address and disseminate state-of-the-art R&D results on the modelling, planning, operation, and control of DER in the context of local energy communities, bringing together researchers from both academia and industry with the goal of fostering interactions among stakeholders. This Special Issue provides a strategic overview of various research topics on mini/microgrids, addressing aspects related (but not limited) to:

  • Optimal design, stochastic programming, and implementation of DER in local energy communities with renewables and energy storage;
  • Coordinated management of distributed energy devices in multicarrier energy systems;
  • Implementation of control and optimization techniques for smooth planning and operation of DER operating in grid-connected and islanded modes;
  • Forecasting techniques to predict renewable power generation, load, etc.;
  • Importance of smart enabling technologies such as energy storage, demand response, electric vehicles, and ICT technologies for the effective penetration local energy communities;
  • Technical issues related to the implementation of local energy communities, also demonstrated through case studies, best practices, and experimental applications.

Demand-Side Generating Assets (DSGAs) relate to existing small diesel Gensets serving the critical loads of infrastructures in unexpected electrical network interruptions. This paper investigates the exploitation of DSGA as potential suppliers of ancillary services (AS), especially in the case of isolated or weak interconnected island power systems such as in Crete. In this regard, their impact on substations’ loading reductions and associated copper losses is presented, using a substation as a case study with a typical touristic load in Crete. DSGA’s impact on such a significant part of reliability enhancement in distribution systems is evaluated, examining different scenarios of DSGA installed capacity. Subsequently, extensive research is carried out regarding the cost analysis for their access to the electrical grid providing AS, in combination with their operating cost analysis. The calculations on fuel consumption cost show that DSGA are comparable with the most expensive gas turbines of the Cretan power system. Finally, considering the capital cost for their required configurations and their fuel consumption cost, a proposal for their remuneration prices is made. The prices that arise are lower than the actual remuneration prices of other similar services such as Genset rentals for the case of the Cretan power system. Full article

Recently, hybrid multi-energy systems consisting of multiple generation, conversion, and storage technologies have been receiving great attention as a promising option to meet the multi-energy demands of residential end-users, by transforming them from passive consumers to active prosumers, who both produce and consume energy. The design problem of such systems is challenging due to the large number of degrees of freedom in the design and operation phases, so the system as a whole must be optimized. Moreover, both economic and low-carbon priorities should be considered in the design problem to foster an effective implementation and deployment. The aim of this paper was to present a methodology for the optimal design of multi-energy nanogrids (MENs) operating in grid-connected and islanded modes. Based on a pre-defined MEN superstructure, a multi-objective linear problem was established to find the types and sizes of the technologies in the MEN, with the aim to reduce the total annual cost and the fossil primary energy input, while satisfying the assigned time-varying user multi-energy demand. With reference to the latter, the thermal behavior of the building was simulated by using the dynamic simulation software TRNSYS. The Pareto frontier was found by minimizing a weighted sum of the total annual cost and fossil primary energy input, and the problem was solved by using branch-and-cut. In the numerical testing, a single-family house of 200 m2 located in Italy was considered as the residential end-user. Results show the effectiveness of the model for providing good balancing solutions for end-users based on economic and energetic priorities. Moreover, it was found that the MEN operating in grid-connected mode showed economic and environmental performances much better than those found for the configuration operating in islanded mode.
