Electrified transportation will minimise greenhouse gas emissions while also lowering gasoline prices. To encourage the adoption of electrified transportation, a variety of charging networks must be established in a user-friendly environment. WEVCS (wireless electric vehicle charging systems) could be a viable alternative technology for charging electric vehicles (EVs) without the need for a plug. The work done in the area of wireless power transfer technology for electric vehicles is described in this paper.

Exchanging information and data using cloud computing in power systems is now becoming common practice. However, there are still many challenges such as data security, interoperability, and scalability that need to be considered. In this paper, the authors have exploited blockchain technology by integrating it with Hadoop to enhance interoperability concerning power system operators at both transmission and distribution levels. A blockchain based approach is developed to exchange information and data within power systems. This approach enables users to exchange information and data without losing ownership or control of the data. The proposed approach provides the solutions to three important issues: scalability, data ownership, and interoperability. The case studies as presented in this paper evaluate the effectiveness of the proposed novel approach for enhancing information and data exchange. The paper specifically evaluates enhanced performance with regard to scalability, latency, and computational time.

Substations are the most critical components of power grids. A failure in a substation may cause power outages for thousands of households and workplaces. That’s why it is crucial to operating substations under proper conditions. Temperature and humidity directly affect the electrical equipment’s lifecycle, performance, and efficiency. They lead to many failures and power outages. This paper presents the humidity-temperature relation inside and outside environments of substations. It also covers the causes and impacts of humidity inside the substations, environmental factors, and mitigating methods of these factors. Besides, some experimental studies are handled such as indoor-outdoor temperature and humidity measurements, basic construction improvements to prevent water ingress and excessive ventilation, and installation of a dehumidifier device. The importance of continuous measurement and controlling of the substation’s indoor environments are proved. Besides, it is presented that the humidity problem can be overcome by avoiding sudden temperature & humidity fluctuations and controlling the indoor climate conditions continuously.

Flywheel Energy Storage (FES) Systems could be exploited to support energy transition maintaining, at the same time, secure conditions in electricity grids. Among the current remunerated services, they can be deployed for Frequency Containment Reserve (FCR) and automatic Frequency Restoration Reserve (aFRR). However, several aspects have to be addressed, such as environmental impacts of these systems, and the costs. Additionally, since the exploitation of scarce raw materials for the assembling, also risk on supply disruption for these materials has to be taking into account. Main indicators exploited to evaluate Flywheels are the Global Warming Potential, the Cumulative Energy Demand, the Levelized Cost of Storage (LCOS) and the Supply Risk Indicator for Raw Materials. Most impacting components for Cumulative Energy Demand and Global Warming Potential are represented by the steel-based Vacuum Chamber and the Power Conversion System. Investment costs and charging costs are instead major contributors in LCOS, whereas replacement costs have a small contribution on it. The Supply Risk, assessed first for raw materials and then aggregated for the entire FES, is influenced mostly by Natural Graphite and Aluminium. Results on risk are almost not affected by considering the elements contained within the FES instead of raw materials. Finally, the comparison between greenhouse gases emitted during the manufacturing stage of alternative Storage Technologies shows that FES is the highest emitter, due to a low Energy on Power ratio.

Distributed multi-energy systems, in addition to their advantages, pose significant challenges to future energy networks. One of these challenges is how these systems participate in energy markets. To overcome this issue, this paper introduces a virtual energy hub plant (VEHP) comprised of multiple energy hubs (EHs) to participate in the energy market in a cost-effective manner. Each EH is equipped with multiple distributed energy resources (DERs) in order to supply electrical, heating and cooling loads. Moreover, an integrated demand response (IDR) program and vehicle-to-grid (V2G) capable electric vehicles (EVs) are taken into consideration to enhance the flexibility to EHs. The manager of the VEHP participates in the existing day-ahead markets on behalf of EHs after collecting their bids. Since EHs are independent entities, a hybrid model of mobile edge computing system and analytical target cascading theory (MECATC) is proposed to preserve data privacy of EHs. Further, to tackle the uncertainty of renewables, a robust optimization method is applied. Obtained results corroborated the proposed scheduling is efficient and could increase the VEHP’s profit about 21.4% in light of using flexible technologies.

Increasing levels of non-synchronous generation prompted by global emissions targets has resulted in power systems with low inertia. This has led to changing system dynamics and evolving trends in system events which are difficult to classify through traditional means. Many countries have invested in Phasor Measurement Units (PMUs) to monitor these systems over large geographical areas which form Wide Area Monitoring Systems. Due to the increased use and improved technology of PMUs this has generated vast quantities of data for system operators to process. Automatic methods for event diagnosis are required due to the complexity of system events, including variable event lengths. This paper demonstrates an approach for the widearea classification of a number of power system events. Event sequencing is used to solve the variability of event lengths. Sequential feature selection is adopted on wide-area synchronized frequency, phase angle and voltage measurements to extract the optimal features. Successful event classification is obtained by employing a Naïve Bayes classifier on the features. The reliability of this method is evaluated using simulated case studies and benchmarked against various sequence lengths.

Swarm Electrification (SE) is gaining considerable attention as an exciting tool to provide last-mile electrification at the lowest possible cost. A swarm grid is similar to a micro-grid, but rather than a planned network, it is assembled in an ad-hoc fashion, simply connecting available equipment via a controller, and expanding the grid as more resources become available. This allows the owners of small solar home systems (SHSs) to sell excess energy and enables others to gain an electrical connection without investing in their own system. Creating an income for the prosumer and helping others to get on the electrification ladder. This paper provides the first review specific to SE, giving an overview of the current state of the technology. A search was performed using the following terms: Swarm electrification, bottom-up electrification, organic microgrids, ad-hoc microgrids, pico-grids, nano grids, mesh grids and P2P energy trading. This yielded 91 publications that implicitly mentioned swarm electrification or described an ad-hoc grid with P2P energy trading. Of these, 48 were selected for this review as they were deemed to represent the key aspects of SE. The main topics within the literature are identified discussed, and the key challenges are noted. It is recommended that further research be performed in the areas of optimisation, stability and reliability with a view to scaling up these grids to support small industrial devices.

The double use of the land in the AgriVoltaic (AV) sites allows to “doubly harvest from the sun’, increasing the land use exploitation with lower environmental impact. This effect strongly depends on the system configuration for both the PV and agricultural sides. The choice is between a high-density PV module arrangement, with high PV production and low agricultural harvesting, or a highly spaced arrangement with lower PV production. The present work presents a case study in Southern Italy: the simulated PV plant can have two different layouts (rated power of 7.13 MW or 5. 6SMW), and each hectare can include the plantation of about 900 Arbequina olive trees.

Due to changes in power networks and increased use of power electronics-based devices as consumer loads, utilities are now facing a problem of capacitive (reverse) reactive power flow in electricity networks. In this paper, the field measurement data from Dutch distribution system operator (DSO) and transmission system operator (TSO) is presented which clearly shows the flow of capactive reactive power occurring in electricity networks. Moreover, the historical data illustrates that there is decline of imported reactive power from transmission system to distribution system over the years. Furthermore, in this paper a case study for a modified CIGRE low voltage (LV) distribution network in DIgSILENT PowerFactory is done where first the capactive reactive power situation is simulated using loads with capacitive power factor and then a solution based on smart inverter function is proposed to minimize the capacitive reactive power exchange between LV and medium voltage (MV) network. In this way, by controlling smart inverters available in distribution network we can manage the amount of reactive power flow in the LV network and at the transmission distribution system boundaries.
