description The invention relates to a single-phase photovoltaic power supply grid-connected inverter hybrid automata control method. According to the invention, a hybrid automata model in the hybrid system theory is adopted, the discreteness in switching of different function operating modes of a grid-connected inverter and the discreteness and the continuity of a switching device in the operating process are fully considered, an instruction signal switching hybrid automata model of different function operating modes of the grid-connected inverter and an on-off combination switching hybrid automata model of the grid-connected inverter switching device are established, and a hybrid automata control system is designed to carry out dynamic control on output of a single-phase photovoltaic power generation grid-connected inverter. The method provided by the invention not only can reflect hybrid behavior characteristics of single-phase photovoltaic power generation grid-connected operations sufficiently, truly, thoroughly and subtly, but also can simplify the design of a controller, improves the reliability and the economy in control for the single-phase photovoltaic power generation grid-connected operations, realizes good combination of efficiency, economy and reliability, has wide practicability and is great in engineering application value.
