Distributed renewable energy generation is lack of intelligent information processing and decision-making section. The above problems can be solved effectively by the means of intelligent information processing technology based on the dynamic structure of multiagent for distributed renewable energy. In order to solve the problems of less data and poor information, this paper puts forward fuzzy hyperbolic model and attempts to use dynamic intelligent information processing technology based on

The selforganizing self-learning and reasoning ability of multi-agent are considered when the information processing. The intelligent information processing section is comprised of three layers and two kinds of agents. The two kinds of agents are Bus Agents and Coordination Agents, and the three structural layers are the data layer, the filter layer and the policy making layer. Moreover the information have been processed could be utilized. 24 Copyright ⓒ 2016 SERSC layer. The data layer fuse the information data transmitted from sensors, and store the results in the database. The filter layer filter the feature data through Belief Revision Function. The policy making layer perform information reasoning and data fusion through the knowledge model of knowledge base, and achieve information sharing, self-learning and modeling by collaboration and coordination among multiple CA. Finally the information we want was obtained. According to the communication mode, agent communication is divided into: blackboard system, federal mode, radio mode, point to point mode. The following were introduced: 1 blackboard system Blackboard model structure is a model to solve the cooperation among many entities to complete the task parallel and distributed computing in different physical environments. The model enables the integration of heterogeneous knowledge sources. The model of it is usually composed of three main parts: the blackboard, knowledge source, control mechanisms, as shown below. The blackboard Control mechanisms knowledge source 1 knowledge source 2 knowledge source n ... ... . 31 deal with it, other agent don't discover the flag, then ignored it. This approach is often used in the case when system is simple, and message type and number are less. point to point mode Generally use the TCP/IP protocol, to establish a physical connection link between the communicate agent. TCP/IP protocol can ensure the information package arrived safely, because it confirmed the end to end. Physical connection means that an agent must know the displacement of other agent in system, agent address either as apart of broadcast information received from the other or obtained from the object which is responsible for agent registration center in system. Multi-agent often use Client/Server (C/S) and Peer-to-Peer (P2P) communication model, following will describe these two communication models. 1 Client/Server (C/S) model In the communication system based on the C/S model , communications among computing inter process must be "transit" through communications server. There has a central server in system. All the client process and server process can communicate bidirectional, and no direct path between the client processes. Figure 3. Block Diagram of C/S Communication Model 2 Peer-to-Peer (P2P) model P2P technology, also called as peer to peer network technology, the central server does not exist in the P2P network structure. In the structure of P2P. Each node most simultaneously has three aspects functional such as information consumption, information provide and information communication rights and obligations owned by each node are peers. The structure of P2P communication model changed from central to distributed, communication between nodes without going through the server forwarding, but direct communication increased communication efficiency, load are more balanced, better reliability. Its model structure shown below: ...... The server process The client process n The client process 2 The client process 1
