Microgrid intelligent measurement and control terminal and method based on multi-agent and heterogeneous communication technology

Abstract

The invention discloses a multi-agent and heterogeneous communication technology based micro-grid intelligent measuring and controlling terminal, a multi-agent system and a measuring and controlling method of the multi-agent system. An element Agent, a micro-grid Agent and an upper-stage power grid Agent form a micro-grid multi-agent system. The intelligent measuring and controlling terminal comprises a master control module, a data acquisition module, a protection control output module and a heterogeneous communication module. The data acquisition module acquires real-time data information of base layer elements in the micro grid, the master control module stores and processes the real-time data information and sends the real-time data information to an upper micro-grid Agent through the heterogeneous communication module. Meanwhile, the master control module receives control instructions of the micro-grid Agent through the heterogeneous communication module and transmits the control instructions to the base layer elements in the micro grid through the protection control output module to control the work states of the elements. The intelligent measuring and controlling terminal and method have the advantages of being capable of achieving mutual communication of micro-grid complex heterogeneous communication networks, wireless, small in size, low in power consumption, low in cost and capable of improving the micro-grid safe and stable operation and power generation efficiency greatly.
