【正文】 quest, the load then is provide by the wind energy and solar energy the demanding energy。) Then (control measures is c。s intuition inference one language expression form. Most monly used is if then, else, also, or and so on, like 2 Uyghur fuzzy inference rule maybe represented as R: If (deviation is a。s experience formalization, the simulation, turns the control model and the language which the puter may accept, lets the puter replace the person to carry on the effective realtime control. Fuzzy controller position diagram like chart 2 3 show It include: The importation quantity faintness turns to connect, knowledge base( database and the rule database), reason logically the machine to reach agreement the faintness to connect. (1)The faintness turns to connect The importation of the misty controller is usually certain quantity, must after faintness turn change into the language that controller know or change the quantity then can be use by the controller, the faintness turns to connect is to convert the certain importation quantity as the faintness to measure, it is also the importation of the misty controller to connect. (2)Knowledge base The knowledge base description form mainly has two kinds of: Database and rule database. Database is deposits all importations and output to change to measure of all misty son gather of belong to one degree relation of vector value。 make possible, lay the foundation for the formation of the misty controller, and get the scholar of the international munity and the engineering technical personnel39。 Studied and has designed one kind based on the graduation fuzzy control (Hierarchical Fuzzy Control, was called HFC) the algorithm energy management system management system. 3. Misty controls The fuzzy set with the fuzzy control concept is by American University of California famous Professor L. A. Z a d e h in it Fuzzy Sets， Fuzzy Algorithm and Rationale for Fuzzy Control and so on famously discusses center first was proposing one kind is pletely different with the traditional mathematics and the control theory intelligent theory. Its production not only developed the broad classical mathematics foundation, moreover was causes the puter science to simulate the significant breakthrough which the human thought aspect developed. The faintness gather to e out the person39。 2LK＝１ mean that two loads connect into the admixture to generate electricity the system devotion work, 2LK = 0 mean that two loads generate electricity the system excision from the admixture. Aim at the characteristics of the system movement, draw up the following design rule: (1)Rule a A power of the breeze electrical engineering capacity that constitutes to mix with to generate electricity the system is more and greatly, as a result the choice regard a power supply of the breeze electrical engineering as principle, the solar cell array is the energy tiny adjust the part. (2)Rule two According to the system work characteristic, takes the direct current side terminal voltage dcU expected value is 216 V, when the renewable energy may output the maximum work rate is bigger than the load request, the renewable energy to the electrical work does not transport the electrical energy. (3)Rule three Takes when here the direct current generator voltage is lower than 192 V, through incorporates the controller to put through the electrical work, by the city electricity supplemented the load needs the short partial electrical energies, and the incorporatio n controller which the chapter introduced by this article behind causes the direct current generator voltage to maintain 192 V, namely SK ＝１ When attracts 200 V, closure incorporation controller, then SK = 0 (4)Rule four 5 Two loads are several: Generate electricity the system for the admixture in the electric power that the assistance facilities need, when can the renewable energy exportation electric power contain surplus of energy, the load that just throw in. In two kind of loads working condition, its load power examination has not been more difficult, in order to avoid two kind of loads frequently throwing 。 SK 和 2LK give or get an electric shock the swit
