In this paper, the hardware realization of the energy management and control subsystem of a grid-connected wind/solar hybrid power system has been introduced. The hybrid power system is based on multi-agents theory, so the control subsystem is regarded as an agent. It is composed of programmable logic controller(PLC), human-machine interface (HMI), grid-connected control module, AC multi-function electric power meters, DC electric power meters, RS485/TCP converter etc., to control and manage the operation of multi-source, such as power grid, wind turbine generation, solar photovoltaic, storage batteries and loads, also to acquire data and communicate with others. In this paper we put the emphases on its hardware, communication and how to meet its requests and functions. Experiments show that this system is competent for both grid-connected mode and stand-alone mode.
