Special Issue Information

Dear Colleagues,

Modern power systems evolve various technological innovations such as distributed renewable energy sources, energy storage devices, electric vehicle charging stations and advanced communication systems. The increasing penetration of distributed energy resources (DERs) into the grid comes with a raft of benefits and opportunities for the power system and its participants. However, the benefits of DERs may not be equitably distributed, especially with an ever-increasing level of renewable energy penetration and introduction of DERs in modern power system, the uncertain and variable nature of renewable energy impose new operation challenges to the electricity market, power system flexibility, resilience, sustainability, and reliability. Fortunately, modern artificial intelligence (AI) techniques such as deep learning and genetic approaches have been developed for addressing these issues in power systems with high renewable energy penetration. At the same time, appropriate policies and regulations are implemented to promote renewable energy integration and distribution in modern power systems. These techniques include but are not limited to marked-based peer-to-peer (P2P) strategies, transactive energy, blockchain techniques, and learning-based forecasting techniques. Integrating all of the aforementioned parts to obtain a sustainable, efficient, reliable, flexible, and resilient modern power system with high DER integration is still an emerging topic needing scientific advancement.

This Special Issue, entitled “Advanced solutions for renewable energy integration and distribution in modern power systems”, aims to present a collection of original, novel contributions focused on advancement in renewable energy integration and distribution technologies in modern power system. Potential topics of interest include, but are not limited to, the following:

  • Distributed energy resource management and optimization
  • Sharing of energy storage
  • Providing demand flexibility to the grid
  • Trading of renewable energy in smart grid
  • Deterministic/probabilistic renewable energy forecasting
  • Modelling flexibility of distributed energy resources
  • 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

Energy Trading on a Peer-to-Peer Basis between Virtual Power Plants Using Decentralized Finance Instruments
by Serkan Seven, Yeliz Yoldas, Ahmet Soran, Gulay Yalcin Alkan, Jaesung Jung, Taha Selim Ustun and Ahmet Onen

Over time, distribution systems have begun to include increased distributed energy resources (DERs) due to the advancement of auxiliary power electronics, information and communication technologies (ICT), and cost reductions. Electric vehicles (EVs) will undoubtedly join the energy community alongside DERs, and energy transfers from vehicles to grids and vice versa will become more extensive in the future. Virtual power plants (VPPs) will also play a key role in integrating these systems and participating in wholesale markets. Energy trading on a peer-to-peer (P2P) basis is a promising business model for transactive energy that aids in balancing local supply and demand. Moreover, a market scheme between VPPs can help DER owners make more profit while reducing renewable energy waste. For this purpose, an inter-VPP P2P trading scheme is proposed. The scheme utilizes cutting-edge technologies of the Avalanche blockchain platform, developed from scratch with decentralized finance (DeFi), decentralized applications (DApps), and Web3 workflows in mind. Avalanche is more scalable and has faster transaction finality than its layer-1 predecessors. It provides interoperability abilities among other common blockchain networks, facilitating inter-VPP P2P trading between different blockchain-based VPPs. The merits of DeFi contribute significantly to the workflow in this type of energy trading scenario, as the price mechanism can be determined using open market-like instruments. A detailed case study was used to examine the effectiveness of the proposed scheme and flow, and important conclusions were drawn. Full article

Distributed energy resources (DERs), recently introduced into distribution systems, are mainly inverter-based distributed generations (IBDGs), which have different short-circuit behaviors from conventional synchronous-based distributed generations (SBDGs). Hence, this study presents a comprehensive analysis of the short-circuit behaviors of distribution systems with IBDGs, based on sequence networks and superposition, from the perspectives of interconnected transformers, and observes the flow of zero-sequence fault currents with different transformer topologies. Moreover, two- and three-winding transformers with various bank connection types and groundings are investigated. It was concluded that the transformer topology and its grounding influence the fault current contribution in zero-sequence networks, and the high penetration of IBDGs alters the fault current magnitude and phase angles.

Rising renewable penetration has accelerated the volatility and instability of the power grid. A small-scale grid is especially vulnerable. Therefore, flexibility and stability enhancement are required for small-scale grids. The interconnection with the large-scale grid through the voltage sourced converter-high voltage direct current (VSC-HVDC) can be a solution to the aforementioned problems. VSC-HVDC can deliver power bidirectionally and change the direction in a short time. Hereby, the cooperative operation of distributed generations (DG) and a large-scale grid through the VSC-HVDC system is proposed in this paper. The VSC-HVDC will take the role of the main source of the small-scale grid. It determines the grid frequency based on its output power. DGs adjust their output power according to the grid frequency, and then the balance between the demand and the supply is maintained. To verify it, a PSCAD/EMTDC simulation was conducted using actual data from Jeju Island, including transmission lines, loads, and climate. Consequently, by the proposed method, the RE share was improved and the grid was operated stably even though the fault situations. Full article

This study proposed a probabilistic methodology based on a confidence interval with the aim of overcoming the limitations of deterministic methods. A stability evaluation technique was required because the output variability of renewable energy can lead to instability of the distribution system. The proposed method can predict the possibility of violating stability in the future. It can also provide a theoretical basis for securing distribution system stability and improving operational efficiency by assessing the in-stability risk and worst-case scenarios. Because of steady-state analysis in the distribution system to which solar power is connected, the probability of violating the standard voltage during the daytime when PV fluctuations are severe was the highest. Moreover, as a result of a simulation of a three-phase short-circuit in the distribution system that is connected to the PV and WT, it was observed that it could violate the allowable capacity of the CB owing to the effects of the power demand pattern and output variability.
