“…In future electricity grids, electric vehicles (EVs) constitute a large share of local community energy demand that could be intelligently controlled. In the case of vehicle-to-grid (V2G) technology, the EVs can also provide bidirectional energy flow support and be considered a sort of mobile battery system [26].…”

Community energy projects have gained popularity in recent years, and encouraging citizens to form local energy communities (LEC) is considered an effective tool for raising awareness about renewable energy. Since no single universal method exists for operating LECs, this study investigated the impact that different business models and asset dispatch methods have on LECs’ economic and energy-related indicators. We carried out a case study, which included the development, modelling, and simulation of seven scenarios using mixed-integer linear programming (MILP). To measure and compare the prospective performance of the LECs in each scenario, six key metrics were evaluated and assessed. The authors find that simple, rule-based control systems might be well suited for LECs with a limited number of controllable assets that aim to provide increased levels of self-consumption of up to 3%. We also conclude that when the LEC utilises an energy cooperative business model, the selected asset dispatch method provides only minor differences in LEC performance, while for prosumer communities, the importance of selecting a suitable asset dispatch method is higher. We also conclude that LECs have the potential to significantly increase their economic performance by more than 10% by acting as aggregators and providing grid services directly to system operators.

“…The rapid integration of renewable energy sources into existing power grids has ushered in a new era of energy production and consumption [1,2], prompting the need for innovative strategies to ensure grid stability and reliability [3,4]. A prominent challenge in this paradigm shift is the management of the demand and supply fluctuations arising from the intermittent nature of renewable sources [5,6]. Among the various potential solutions, the utilization of battery electric vehicles (BEVs) as a flexible grid resource has garnered considerable attention owing to their remarkable energy-storage capabilities and short response times [7,8].…”

Battery electric vehicles (BEVs) are increasingly recognized as the key to the power industry's shift towards decentralization, carbon neutrality, and electrification because of their potential as flexible assets. Advances in grid integration, communication standards, smart charging, vehicle-to-grid technology, and electric vehicle service platforms are crucial for effectively leveraging BEVs. However, realizing these potential hinges on the active participation of electric vehicle owners, which is a vital yet challenging aspect. This study proposes a gamification-based incentive model to boost the participation of BEV owners in demand response programs, focusing on enhancing grid flexibility. A pilot project involving BEV drivers and charging-point operators was conducted on Jeju Island, South Korea. The significant contributions of this study include the development of both hardware and software systems for the gamification model and an ANOVA analysis to assess its impact. Compared with conventional economic incentives, the application of gamification-based incentives had effects of 13.8-69.2 percent from a demand increase perspective and 2.0-91.4 percent from a demand reduction perspective.

“…Nonetheless, they require a lot of time and effort to be implemented in order to avoid the overfitting of the data while maintaining a good accuracy. [41][42][43][44] For the case in which EV chargers are used as APFs, [45][46][47][48] they success in reducing harmonic content but they also involve a high development cost, even more if they are designed for both reducing harmonics and giving grid support. 49,50 Many control strategies focus on selective harmonic elimination (SHE) algorithms, [51][52][53][54] but most are based on multilevel converters, which despite their better harmonic response are more expensive in cost, and require more volume and weight as they consist of more elements.…”

Vehicle‐to‐grid charging control strategy aimed at minimizing harmonic disturbances

This paper presents the design and implementation of a control for an electric vehicle charger to provide vehicle to grid (V2G) services while reducing the current total harmonic distortion (THD). The control is composed of two current loops. The main one controls the active and reactive powers in a decoupled way, and the second one, focuses on the reduction of the fifth order harmonic component. After explaining the mathematical modelling, the meth-
