VPP Frequency Response Feature based on Distributed Control Strategy

Virtual power plant(VPP) integrate distributed power, energy storage device and load, through reasonable control mode, the virtual power plant will have the same controllable external characteristics as the traditional power plant, such as maximum power generation capacity, minimum technical output, climbing rate, and frequency regulation characteristic etc. This paper presents a control strategy for the frequency modulation characteristics control of virtual power plant, which is suitable for the non-center control, by the pinning node of directly receiving the power grid dispatching instruction to convey information to all nodes in the virtual power plant, complete distributed pinning control, to meet the power grid scheduling requirements for the overall power adjustment. The numerical examples are verified by the electricity communication interactive simulation platform, power simulation is done by MATLAB, and the communication simulation is done by OPNET, through COSIM interactive interface, interactive simulation platform will be able to simulate the impact of different communication architecture on frequency modulation control performance. The numerical examples show that the distributed pinning control strategy could effectively accomplish the task of frequency modulation control in virtual power plant, and make a beneficial exploration for virtual power plant engineering practice.
