As a kind of abundant, clean and renewable energy source, wind/photovoltaic hybrid power (WPHP) has been the important topic of research. At present, at home and abroad, research on WPHP is mainly focused on wind turbine manufacture and control, photovoltaic power unit manufacture and control, and also the optimization design of wind/photovoltaic hybrid power farm (WPHPF). There is less report about energy management and control of WPHPF.Wind/photovoltaic hybrid power systems (WPHPS) are open, distributed systems, whose power devices scatter all over the power farm. These devices are running independently, and cooperating with each other with wind, solar energy and change of load, to make WPHPS are running safely, stably, high-quality, economically. Aiming at these characteristics of WPHPS, and based on collecting, analyzing, generalizing material about WPHP at home and abroad, build wind/photovoltaic hybrid power management and control systems based on multi-Agent (WPHPMCS).The primary research is as follows:1. Aiming at the characteristics of WPHPS and MAS, MAS technique was imported to WPHPS, and WPHPMCS was build, which accorded to the large size WPHPF has many power devices and scatters in a large farm. The control systems had many merits such as strong adaptivity, good openness and fault-tolerance.2. The cooperation of MAS was researched. Aiming at the shortcoming of contract net protocol (CNP), an improved contract net protocol (ICNP) was presented. At the same time, ICNP was applied to an instance of WPHPS to show the protocol was suit the cooperation of agents in WPHPS. Aiming at cooperation between Agents in long time, an improved double auction used on Multi-Agent cooperation protocol (IDAP) was also presented, and it was applied to WPHPS. The emulational result indicated this protocol could improve the stabilization of WPHPS.3. The development of WPHPMCS was presented. It also presented the development's hardware, software environment, used software and database systems. The development of two module was presented detailedly.
