Special Issue Information

Dear Colleagues,

The deployment of distributed energy resources (DERs) and renewable energy resources in electrical grids is significantly increasing throughout the world. Influenced by the increasing penetration of “behind-the-meter” DERs, power systems are experiencing a paradigm shift from a centralized structure to a decentralized one. DERs encompass a range of consumer level technologies used by households and businesses, such as inverter connected solar PV, electrical energy storage (EES) systems, energy management systems, and electric vehicles (EVs). An increasing number of customers in electricity markets are seeking to mitigate rising electricity prices and reduce their greenhouse gas emissions by deploying their own on-site renewable generation and storage.

However, the high penetration level of DERs raises technical, commercial, and regulatory challenges, since the grid infrastructure is designed to deliver large-scale centralized generation to consumers rather than to integrate millions of consumer-owned generators. These changes will require the development of innovative approaches and technology solutions to ensure the efficient integration and coordination of DER. Efficient DER integration is expected to increase the value of local management of these resources and provides DER owners with the opportunity to maximize the return on their investment taking into account the increasing digitalization of the energy sector with more advanced communication technologies. From a grid perspective, coordinated and controlled use of DERs can provide substantial benefits for the stability of the broader network.

This Special Issue, entitled “Innovative Solutions for Integration of Distributed Energy Resources” for the international journal Sustainability, mainly covers original research and studies related to the abovementioned topics including, but not limited to:

  • Integration of DER into power systems
  • Management of distributed and renewable energy resources
  • Demand response integration for DER management
  • Use of energy storage systems
  • Integrated community-based energy systems
  • Local energy systems
  • Renewable energy hosting capacity
  • Market design for flexibility services
  • Local energy trading, market mechanisms and business models
  • DER participation in future electricity markets under uncertainty
  • Transactive energy for DER management
  • Peer to peer and community-based trading in local market
  • Aggregation of DER in virtual power plants
  • Digitalization in energy systems
  • Role of IoT in DER integration

An intrinsically stable microgrid, operated by inverter-interfaced distributed energy resources (I-DERs) is introduced in this paper. The microgrid is built upon a systematic design method, which is adapted from the operation of the synchronous machine (SM). The proposed method analogizes the dynamics of the dc-link in I-DERs to the rotor dynamics in synchronous generators (SGs) and utilizes the capacitor as energy storage. Thus, the proposed mechanism relaxes battery usage for frequency control, and by using the capacitive stored energy, provides a high fault ride-through capability, which is suitable for both on-grid and off-grid applications. Based on stability analysis of the SG and the dynamic state matrix eigenvalues for multimachine power system, the dc-link capacitor of I-DERs is characterized in the context of microgrid. The dc-link capacitor stores kinetic energy similar to the rotor of the SG and provides inertia in transients without the need of battery storage. The inverter angle responds to the change of the dc link voltage (energy). The dc-link voltage is then controlled similar to the field control pertaining to the SG. Finally, a governor-like mechanism is applied to maintain dc-link voltage stability. Simulation and experimental results are provided to show the effectiveness of the proposed design mechanisms.
