Special Issue Information

Dear Colleagues,

In the current context, the transition to a low-carbon energy paradigm is fundamental, where the time window—for climate change to remain at a tolerable level—is increasingly shorter. One of the essential pillars to accelerate this transition is renewable energy generation, which is gaining increasing prominence as it matures in its efficiency and profitability.

Thus, the great challenge we must overcome is reducing fossil fuel use and investing in technologies that prioritize renewable energy. This option is the best from an ecological point of view, but it has negative points that must be taken into consideration (e.g., hydro requires the construction of dams that lead to significant impacts; wind and solar depend on external factors for energy generation, making it difficult to depend exclusively on these sources).

The complexity of the management associated with these processes has increased exponentially, going from a model where generation was centralized and easily managed to one of distributed generation and where there is significant fluctuation in generation. Grid operators will have to manage this evolution to achieve a key objective: stability in generation and availability to respond to fluctuation, which is now at both ends of the spectrum—generation and demand.

The answer to these challenges lies in technology and new concepts. Technology must be able to obtain real-time information from the different generation units—renewable and non-renewable—and manage their entry and exit from the grid to ensure their stability. New technologies, such as the Internet of Things and sensors to transmit information on asset utilization, Artificial Intelligence and Machine Learning to anticipate scenarios and improve efficiency levels, are essential components of a solution capable of responding to the complexity of this challenge. This involves the creation of a solution that allows the management of the portfolio of renewable resources with maximum efficiency and the use of available assets. Another intrinsically necessary characteristic is the scalability of the solution, which allows the easy integration of new assets and the optimization of their use. Finally, given the diversity of systems, it is essential that the management system can interconnect and obtain data from the most diverse systems, ensuring a bidirectional connection that allows their management.

The future of energy is distributed, with low emissions and with microgeneration playing important roles, integrating new concepts to accommodate fluctuations. Technology is the answer to making the future predictable, manageable, and integrated.

This Special Issue addresses management and optimization for renewable energy. The focus includes the methods and techniques regarding the planning/operation of power systems with a high penetration of renewables. Approaches to integrating these resources into electricity markets, as one of the main drivers for their efficient use, are also welcome.

Regulatory boards are promoting closed distribution systems (CDSs), which are different from traditional public-access networks, that can be owned and managed by energy communities (ECs). The inclusion of local renewable energy potential and an adequate schedule of storage devices in a CDS allow cooperation among the EC’s members in order to reduce operational expenditure (OPEX), providing internally competitive electricity prices with respect to those provided by publicly regulated networks and electricity markets. The CDS operators can assume a new role as the centralized energy dispatchers of generation and storage assets in order to maximize the profits of the members of the EC. This paper proposes an innovative optimal active and reactive power dispatch model for maximum community welfare conditions. A key difference between this proposal and existing social-welfare-based dispatches on public-access networks is the exclusion of the profit of the external wholesale electricity market. The focus of the proposed method is to maximize the welfare of all community members. A remuneration framework based on a collective EC with a single frontier is adopted, considering agreements between members based on locational marginal pricing (CDS-LMP). Results from an illustrative case study show a reduction of 50% in the EC’s OPEX with a payback time of 6 years for investments in CDSs, renewable sources, and storage. Full article

Electric vehicles are an emerging topic in organizations and society. Access to economically and environmentally workable sustainable technologies has become a priority in the face of catastrophic climate change and the discussion surrounding it. This study examines the academic literature to shed light on factors, trends, emerging models, and critical perspectives on electric vehicles and their relationship to value creation, strategic management, and sustainability. This research uses a bibliometric analysis method to explore the dynamic interaction between these essential elements of the literature. The source is the Scopus database. The analysis uses VOSviewer software 1.6.20, focusing on the bibliographic coupling of documents, which was presented as a network visualization map. It emphasizes search terms proving the emerging need for innovation strategies in automotive industry organizations, consumers, and public entities to create value within a global sustainability logic. This study highlights the relationship between the electric vehicle industry and the value creation strategy and sustainability in a digital world. Full article

This paper presents a novel modular voltage control algorithm for optimal scheduling of a distribution system’s load tap changers to minimize the number of tap changes while maintaining a voltage deviation (VD) around a desired target. To this end, a bi-objective optimal voltage regulation (OVR) problem is addressed in two distinct stages. First, the operational constraint on the load tap changer is removed to form a single-objective OVR problem relating to the voltage. The solution obtained in this stage is ultimately utilized to determine the penalty value assigned to the distance from the optimal (solely in terms of voltage) control value. In the second stage, the optimal scheduling problem is formulated as a minimum-cost-path problem, which can be efficiently solved via dynamic programming. This approach allows the identification of optimal scheduling that considers both the voltage-related objective as well as the number of load tap changer switching operations with no added computational burden beyond that of a simple voltage optimization problem. The method imposes no restriction on the load tap changer’s operation and is tested under two different target functions on the standard IEEE-123 test case. The first attains a nominal voltage with a 0.056 p.u. voltage deviation and the second is the well-known conservation voltage reduction (CVR) case with a 0.17 p.u. voltage deviation. The method is compared to an evolutionary-based algorithm and shows significant improvement in the voltage deviation by a factor of 3.5 as well as a computation time acceleration of two orders of magnitude. The paper demonstrates the effectiveness and potential of the proposed method as a key feature in future cutting-edge OVR methods. Full article
