Special Issue Information

Dear Colleagues,

This Special Issue, ‘Advances in Power and Energy Management for Distribution Systems with High Penetration of Distributed Energy Resources’, aims to focus on the critical challenges and innovative solutions related to the integration of distributed energy resources (DERs) into distribution systems as well as their active management. With a growing emphasis on sustainability and renewable energy sources, distribution systems are experiencing a rapid influx of DERs, such as solar panels, wind turbines, electric vehicles, and energy storage. To effectively manage these resources, two key technologies take center stage: Advanced Distribution Management Systems (ADMS) and Distributed Energy Resource Management Systems (DERMS).

ADMS serves as the epicenter of modern distribution grids. It combines real-time monitoring, control, and analytics to optimize grid operations, ensure reliability, and enhance grid resilience. This Special Issue seeks to explore the latest developments in ADMS, including advanced data analytics, grid automation, and predictive maintenance techniques, all aimed at accommodating DERs seamlessly.

In parallel, DERMS plays a pivotal role in the integration and active management of DERs and microgrids within distribution networks. DERMS offers utilities with the tools to harness the full potential of DERs, enabling grid operators to manage distributed energy generation, storage, and demand efficient response. This Special Issue invites papers that address topics such as DER aggregation, demand-side management, microgrids, and grid-edge intelligence.

Together, ADMS and DERMS are indispensable for utilities seeking to balance supply and demand, reduce losses, and optimize grid performance while accommodating the complexities of high DER penetration. Therefore, this Special Issue aims to collate cutting-edge research and insights from researchers and practitioners in these fields, shedding light on the evolving landscape of power and energy management in distribution systems, thereby fostering sustainable and resilient energy infrastructure for the future.

Topics of interest include, but are not limited to, the following:

  • Integration of high penetration of DERs, such as distributed generation (DG), electrical vehicles (EV), and energy storage technologies;
  • Active management of distribution grids with high amounts of dispersed DERs;
  • Non-wire alternatives (NWAs);
  • Advancements in ADMS, DERMS, and microgrid management technologies;
  • Harnessing the potential of behind-the-meter DERs;
  • Electrical vehicles as flexibility resources for distribution operations;
  • AC and DC microgrid control, protection, and management.

This paper presents a novel methodology for short-term load forecasting in the context of significant shifts in the daily load curve due to the rapid and extensive adoption of Distributed Energy Resources (DERs). The proposed solution, built upon the Similar Days Method (SDM) and Artificial Neural Network (ANN), introduces several novelties: (1) selection of similar days based on hidden representations of day data using Autoencoder (AE); (2) enhancement of model generalization by utilizing a broader set of training examples; (3) incorporating the relative importance of training examples derived from the similarity measure during training; and (4) mitigation of the influence of outliers by applying an ensemble of ANN models trained with different data splits. The presented AE configuration and procedure for selecting similar days generated a higher-quality training dataset, which led to more robust predictions by the ANN model for days with unexpected deviations. Experiments were conducted on actual load data from a Serbian electrical power system, and the results were compared to predictions obtained by the field-proven STLF tool. The experiments demonstrated an improved performance of the presented solution on test days when the existing STLF tool had poor predictions over the past year. Full article

The operation of the utility grid is being reshaped by the continuous addition of distributed energy resources and advanced metering infrastructure, which challenge existing grid control strategies. Some utilities deploy advanced distribution management systems (ADMS) to assist with the consolidation of various applications and to augment situational awareness in response to the new power delivery dynamics. An ADMS is an integrated software platform that provides utilities with a way to enhance their reliability, control, and optimization with advanced applications, such as volt/VAR optimization (VVO). A VVO application could serve as a vehicle to deliver cost savings by providing the utility with a method to reduce rates by controlling the voltage and decreasing the energy usage in their service territory. Some utilities are reluctant to integrate an ADMS, because it is a significant investment that requires approval from the public regulatory commission and/or their customers. This paper evaluates the impact on VVO performance when using a lower-quality network model supplemented with additional measurements, which could provide an implementation for cost savings. The results show that a better model quality would provide the highest energy savings; however, some level of telemetry is necessary in all scenarios to prevent voltage exceedances. Full article

The traditional fixed value assessment of the renewable distributed energy hosting capacity of a distribution network cannot accurately and comprehensively reflect the change in hosting capacity; therefore, we propose the interval assessment method for the renewable distributed energy hosting capacity of a distribution network. The renewable distributed energy hosting capacity interval consists of an optimistic upper boundary and a pessimistic lower boundary. First, the optimistic upper bound is described by a deterministic model that takes into account the constraints of safe system operation. Second, the pessimistic lower bound is portrayed by a two-layer robust assessment model that accounts for the DG temporal uncertainty, DG spatial uncertainty, and active distribution network flexible resource dispatch uncertainty. Each pessimistic sub-model was constructed in turn, and then the model was solved by linear simplification using pairwise transformation, as well as McCormick relaxation. Finally, simulations were carried out in the IEEE 135 system, and the results validated the effectiveness and practicality of the proposed method. Full article

In September 2020, the Federal Energy Regulatory Commission (FERC) released Order 2222, which opens wholesale markets to small-capacity distributed energy resources (DERs), recognizing their potential in improving operational efficiency by providing bulk grid services. Therefore, a co-simulation capability that can connect transmission and distribution (T&D) simulations and evaluate the impacts of DER provision of bulk grid services is needed. In this paper, we present a new integrated T&D co-simulation platform that incorporates T&D system simulators, DER aggregator/group strategies, and a co-simulation coordinator. Industry-standard communication protocols are employed to mimic real-world conditions. Secondary frequency regulation is selected as the representative bulk grid service, and we simulate the responses of DERs to the frequency regulation signals. The simulation results for a solar-rich distribution feeder in Colorado, USA, demonstrate how the T&D co-simulation setup is used to evaluate the contributions of DERs to minimize the bulk grid frequency deviation.

The ocean energy resources hold the promise of a sustainable solution within global efforts to diversify energy sources and mitigate climate change. Wave energy conversion (WEC) systems, as emerging technologies, offer adaptability and the potential to harness predictable wave energy. However, integration of WEC systems into a power grid brings challenges for system operators due to their nature of operation. Addressing these demands is a multilayered process that involves highly efficient power electronic devices, control systems, and efficient energy storage solutions. This paper specifically focuses on the methodologies of the grid integration of a specific wave energy conversion system—a point absorber developed by the company Sigma Energy. Proposed methodologies are experimentally tested using power hardware-in-loop (PHIL) emulation of a fully monitored and controlled small-scale microgrid equipped with a battery energy storage system (BESS), different emulators of loads, and distributed generators (DG).
