“…As the most popular energy storage device, battery is utilized in this study for its high energy density. In the meantime, SMES is also utilized in this study for its high power density, high cyclic life, fast dynamic response, and the ability to deliver high levels of current in a short amount of time [25,26]. Since battery is normally a microgrid component, there is no need to implement a specialized battery storage system for the MMGs.…”

Multiple microgrids (MMGs) are clusters of interconnected microgrids that have great potential for integrating a large number of distributed renewable energies (DREs). The grid-connected control scheme is important for the exploration of the MMGs’ operation potential. In this paper, a multi-layer coordinated control scheme for DC interconnected MMGs is proposed to optimize their operation and improve their operation friendliness. An adaptive droop control method is designed for the DC connection interfaces of the MMGs to adaptively manage the power exchange among the sub-microgrids. Meanwhile, the strategy of power fluctuation suppression is developed for the hybrid energy storage system (HESS) in the MMGs. The coordination among the sub-microgrids and the HESS is then clarified by the proposed control scheme to optimize the AC tie-line power and make the MMGs a highly coordinated collective. A case study is performed in PSCAD/EMTDC based on the demonstration project in Guangxi, China. The results show that the proposed multi-layer coordinated control scheme realizes the coordinated operation of the MMGs, fully exploits the complementarity of the MMGs, and improves the operation friendliness among the sub-microgrids and the utility grid. Thus the integration and utilization of a large number of DREs is enhanced.

Low-Cost Implementation of Passivity-Based Control and Estimation of Load Torque for a Luo Converter with Dynamic Load

In this paper, passivity-based control (PBC) of a Luo converter-fed DC motor is implemented and presented. In PBC, both exact tracking error dynamics passive output feedback control (ETEDPOF) and energy shaping and damping injection methods do not require a speed sensor. As ETEDPOF does not depend upon state computation, it is preferred in the proposed work for the speed control of a DC motor under no-load and loaded conditions. Under loaded conditions, the online algebraic approach in sensorless mode (SAA) is used for estimating different load torques applied on the DC motor such as: constant, frictional, fan-type, propeller-type and unknown load torques. Performance of SAA is tested with the reduced order observer in sensorless mode (SROO) approach and analyzed, and the results are presented to validate the low-cost implementation of PBC for a DC drive without a speed and torque sensor.

“…However, IDA-PBC with a desired energy function consisting of quadratic and exponential functions is proposed in [37] for the same system to improve the life time of FC. In [38], IDA-PBC is used for the robustness improvement of a SMES control in microgrid applications. In [30], IDA-PBC is designed for the grid connected converter to improve power quality under non-ideal grid conditions.…”

In this study, energy management and damping improvement of a DC microgrid are proposed by using an interconnection and damping assignment-passivity-based control (IDA-PBC) technique. The control technique is applied for (i) the grid connected inverter and (ii) the DC-DC converters connected with fuel cell and battery of the DC microgrid to control the DC bus voltage. The IDA-PBC generates the control laws with the desired energy function for the current controller of the converters based on the generation from the renewable power generators and load demand. In addition, an integral action is added with the IDA-PBC control laws to reduce the steady-state error in the DC bus voltage. The parameters of the IDA-PBC technique are tuned based on the state of charge of the battery and grid availability for a smooth transition between the operating modes and better energy management. It is proved that the derived energy function satisfies the Lyapunov stability criterion. Simulations are carried out in MATLAB/Simulink to test the performance of the proposed control technique. The results show that the proposed technique provides the desired damping and energy management.
