“…The protocols currently used in the power field include the Distributed Network Protocol (DNP) 3.0 protocol and the IEC 61850 protocol. For data acquisition and control in distributed power systems, the Control Area Network (CAN) and Modbus protocols are heavily used [35], [36]. Among them, the Modbus Remote Terminal Unit (RTU) method is in the form of 8-bit binary data and has excellent transmission efficiency, so it is widely used in parallel operation systems.…”

As power demand from electric vehicles and digital loads increases, the use of direct current power supplies is increasing. As a result, the application of microgrid utilizing various distributed power systems is expanding. As demand power and load capacity increase, parallel operation of multiple power converters is required to increase the capacity of power converters used in distributed power systems. Among parallel control methods, load sharing through communication has a significant effect on control performance due to communication speed and reliability. This paper proposes an instantaneous load-sharing parallel control method using a high-speed communication method that can transmit data necessary for load-sharing every control cycle. The proposed communication method uses enhanced PWM and capture communication using a DMA module to compensate for the shortcomings of the existing method using PWM and capture functions. Whenever the master voltage controller is executed, the data required for parallel operation is updated, and by transmitting this data to the slave, instantaneous load sharing control with high speed response is possible. We explain the communication and system architecture of the proposed method and present the communication protocol specifications and design. The performance and validity of the proposed instantaneous load sharing parallel control method were verified through simulation and experiments.INDEX TERMS parallel control methods, current distribution, pulse width modulation (PWM), direct memory access(DMA), power conversion

“…However, with the advances of technology, CAN became suitable for many other applications in different branches of technologies. In [6], a master-slave control strategy of a microgrid over CAN bus is presented, to control parallel DC/AC inverters. In [7], CAN is used as a means of communication in the control of velocity and position in motor driver modules, to overcome the limitations of RS-232 and RS-485.…”

This paper presents the initial developments of new hardware devices targeted for CAN (Controller Area Network) bus communications in forest machines. CAN bus is a widely used protocol for communications in the automobile area. It is also applied in industrial vehicles and machines due to its robustness, simplicity, and operating flexibility. It is ideal for forestry machinery producers who need to couple their equipment to a machine that allows the transportation industry to recognize the importance of standardizing communications between tools and machines. One of the problems that producers sometimes face is a lack of flexibility in commercialized hardware modules; for example, in interfaces for sensors and actuators that guarantee scalability depending on the new functionalities required. The hardware device presented in this work is designed to overcome these limitations and provide the flexibility to standardize communications while allowing scalability in the development of new products and features. The work is being developed within the scope of the research project “SMARTCUT—Remote Diagnosis, Maintenance and Simulators for Operation Training and Maintenance of Forest Machines”, to incorporate innovative technologies in forest machines produced by the CUTPLANT S.A. It consists of an experimental system based on the PIC18F26K83 microcontroller to form a CAN node to transmit and receive digital and analog messages via CAN bus, tested and validated by the communication between different nodes. The main contribution of the paper focuses on the presentation of the development of new CAN bus electronic control units designed to enable remote communication between sensors and actuators, and the main controller of forest machines.

With the development of renewable energy sources, the microgrid is widely implemented because of its flexibility and high-efficiency. It makes the most use of distributed generators and energy storage systems, which can supply the local load with minimum energy loss. However, there are always two concerns in the microgrid. The first one is power sharing. Generally, power sharing is designed to be proportional to the generator's capacity to reach the highest efficiency. Droop control, which is well-known for its noncommunication control strategy, can achieve proportional active and reactive power sharing among parallel power converter systems. However, its feasibility can be seriously influenced by some additional factors, such as line impedance mismatch,
