As China proposes to achieve carbon peak by 2030 and carbon neutrality by 2060, as well as the huge pressure on the power grid caused by the load demand of the energy supply stations of electric vehicles (EVs), there is an urgent need to carry out comprehensive energy management and coordinated control for EVs’ energy supply stations. Therefore, this paper proposed a two-step intelligent control method known as ISOM-SAIA to solve the problem of the 24 h control and regulation of green/flexible EV energy supply stations, including four subsystems such as a photovoltaic subsystem, an energy storage subsystem, an EV charging subsystem and an EV battery changing subsystem. The proposed control method has two main innovations and contributions. One is that it reduces the computational burden by dividing the multi-dimensional mixed-integer programming problem of simultaneously optimizing the 24 h operation modes and outputs of four subsystems into two sequential tasks: the classification of data-driven operation modes and the rolling optimization of operational outputs. The other is that proper carbon transaction costs and carbon emission constraints are considered to help save costs and reduce carbon emissions. The simulation analysis conducted in this paper indicates that the proposed two-step intelligent control method can help green/flexible EV energy supply stations to optimally allocate energy flows between four subsystems, effectively respond to peak shaving and valley filling of power grid, save energy costs and reduce carbon emissions.

OpenPLC is an open-source software that complies with IEC 61131-3 international standard and has been widely used by researchers to validate PLC logic execution. However, the software’s capability is limited as it is solely restricted to Modbus and DNP3 protocols. With the integration of intelligent electronic devices (IEDs) into modernized power grid based on IEC 61850 standards, it is necessary to incorporate functionalities that enable PLCs to communicate with IEDs. Therefore, in this paper we develop OpenPLC61850, which is an extended version of OpenPLC and is compatible with the IEC 61850 protocol. The architecture and the procedure involved with PLC logic execution, IED communication, and SCADA connectivity are explained in this paper. As the proposed software is also an open source, we believe that this would be helpful for researchers for conducting smart grid research.

Intelligent energy facilities, e.g., smart grids and microgrids are the evolution of traditional energy grids through digital transformation. These modern paradigms are expected to foster the utilization of renewable energies, sustainable development, and resilience of the power grid. A barrier found when deploying experimental smart grids and microgrids consists of handling the heterogeneity of the required hardware and software components as well as the available commercial equipment. Despite the fact that there is various architecture proposed in previous literature, it commonly lacks experimental validation, specification of involved equipment concerning industrial/proprietary or open-source nature, and concretization of communication protocols. To overcome such drawbacks, this paper proposes an innovative multi-layered architecture to deploy heterogeneous automation and monitoring systems for microgrids. The architecture is structured into six functional layers to organize the hardware and software equipment in an integrated manner. The open protocol Modbus TCP is chosen to harmonize communications, enabling the interconnection of equipment from industrial and energy scopes, indeed of open-source nature. An experimental photovoltaic-based smart microgrid is reported as the application case to demonstrate the suitability and validity of the proposal.

Renewable Energy Generation

Power grid models are important in relation to several topics and applications, especially the modelling, optimisation and extension of electrical grids. The significance of grid models is heightened by the increase in renewable energy generation and the challenges associated with its integration into the power grid. However, despite their crucial importance, grid models have generally not been made publicly available for scientific studies or technical analyses. Little information has been published about either the details and methods used in the derivation of these models, or their input and output data. Recently, several projects were initiated in an effort to address this by developing open source grid models and associated data. These projects used different approaches and methods, but most are based on the OpenStreetMap database. The goal of this paper is to compare the different available grid models on the basis of the structure and derivation methods used. Therefore, a novel combination of a graph-theoretical, Geographic Information System (GIS)-based and power-related comparison level is introduced using the open source tool AutoGridComp, which was developed by the authors. The grid models considered in this study are the Scientific Grid Model (SciGRID), GridKit and open street map Transmission Grid Model (osmTGmod) models for Germany.
