ent control the fuzzy control technology (Fuzzy Control, is called FC) to realize to the system carries on the management and the control。 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。 s judgment, the thinking process with the direct expression of more simple language and mathematics forms. The mode of thinking that makes plicated system press mankind carry on operation and processing’s39。 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。 s extensive value and 6 applications. The fuzzy control through the fuzzy set with the logical inference method person39。 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。 If in order to continue the area, the theory area database then for belong to the function correspond. The regular storehouse is the operator which and has the rich experience based on the expert knowledge acts according to the longterm accumulation the experience, according to person39。 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。 Bad rate of change is b。 ) Then (control measures is c。 ) The rule database is to is use to deposit all misty control rules, while reason logically provide the inferential basis for reason logically the machine. (3)Reason logically to reach agreement the faintness to connect While reason logically, the controller reasons logically the machine according to the misty quantity that input, controlling the rule through the faintness to solve the faintness to 7 relate to the square distance, obtaining the misty control quantity of the misty controller. From reason logically the amount of control that machine acquire and is a misty vector, can39。 t be use directly to control to be control object, must still convert the certain control measure, we be called this process to solve the faintness or faintnesses to measure clear to turn. Usually reason logically and the exportation carries to have to convert the misty quantity as clear value of process be called the solution faintness. 4. Designs of the ＥＭＳ This article designs the wind can a solar energy mix generating system structure diagram like chart 2 6 show For the sake of the exaltation can the exploitation efficiency of the renewable energy, under the condition that wind energy and solar energies can satisfy to load the request, the load then is provide by the wind energy and solar energy the demanding energy。 At the wind energy and solar energies can39。 t satisfy the load request, at making use of well can the foundation of the renewable energy up, the load is provided together by the wind energy, solar energy and charged barbed wire s the demanding energy. May know by the system structure drawing, the system direct current generator voltage change direct influence system provides the electrical energy to the load the quality and the reliability, thus the stable DC voltage is the system operational reliability and a performance important target. Takes the system direct current generator voltage for to control the quantity, 2 6 may result in the system by chart 2 the mathematical model: Among them dcU —female line electric voltage of direct current, wi —the wind power equips the exportation electric current, PVi —the solar energy generates electricity to equip the exportation electric current, Li —the system transport the load get electric current, 8 Si —the charged barbed wire transports to give or get an electric shock the direct current the part get electric current, an electric capacity of C—direct current. The usual renewable energy electric power facility investment is bigger, in order to fully displays its electricity generation the efficiency, reduces system cost the recycling cycle, the electric power facility uses the maximum work rate output for the control goal. Supposes each winddriven generator and each group of solar cell arraya。
