ＥＭＳ的設計 本文所設計的風能一太陽能混合發(fā)電系統(tǒng)的結構框圖如圖２－６所示： 為了提高可再生能源的利用效率，在風能和太陽能能夠滿足負載要求的情況下，負載所需求的能源則由風能和太陽能提供；在風能和太陽能不能滿足負載要求時，在充分利用可再生能源的基礎上，負載所需求的能源由風能、太陽能和電網(wǎng)共同提供。最常用的為 if－ then， else, also, or 等，如 2維模糊推理規(guī)則可表示為 Ｒ： if（偏差 is a；差變化率 is b；） then（控制量 is c；） 規(guī)則庫就是用來存放全部模糊控制規(guī)則，在推理時為 “ 推理機 ” 提供推理的依據(jù)。即能量管理系統(tǒng)結構圖如圖 2－ 2 所示： EMBED , EMBED , EMBED , EMBED 和 EMBED 分別為系統(tǒng)的直流母線電壓、風力機可輸出的最大功率、太陽能電池陣列可輸出的最大功率、系統(tǒng)中一類負載所需功率和二類負載所需的功率； EMBED 和 EMBED 分別為系統(tǒng)的風力機輸出利用系數(shù)和太陽能電池陣列輸出利用率，即 EMBED 為風力機啟用的臺數(shù)與風力機總數(shù)之比 , EMBED 為 太陽能陣列啟用的組數(shù)和太陽能陣列組總數(shù)之比。在設計風一光發(fā)電系統(tǒng)中，普遍采用的設計思路是根據(jù)負載每天的總耗電量，和由當?shù)貧庀髷?shù)據(jù)得到的日輻射量來確定太陽能電池陣列、風力發(fā)電機的容量，再來確定可再生能源發(fā)電控制裝置的功率和蓄電池容量，但是在混合發(fā)電系統(tǒng)的運行控制和優(yōu)化管理方法方面的研究較少。 Bad rate of change is b。 The spring stanza breeze of winter is strong but the sunlight is opposite weaker. Develop the wind force a solar energy to supply again to give or get an electric shock the system with each other, take into wind force and the solar energy techniques to synthesize the exploitation, thus constitute a kind of repair with each other of can scatter the new energy that cloth order, will is a new growth to order in this energy structure of century. Have the condition pass the storage battery of match the appropriate capacity or connect into the city to give or get an electric shock the conduct and actions back up power supply, can make circulate the expenses to lower consumedly, huge exaltation of the credibility of the power supply. Local mainly generate electricity to independent wind power, the light currently and the breeze a light supplies again the research of the electricity control system with each other more. In design the breeze a light generate electricity system, the design way of thinking of the widespread adoption according to load everyday total to consume the electricity quantity, and radiate the quantity from the day that the local weather data get to the capacity of the certain solar cell array, the wind power machine, then e certain can the renewable energy generate electricity the power and the storage battery capacities of control the devices, but at mix with the movement of generate electricity the system control and excellent turn the research of manage the method less. Because the exportation power and the burden powers of the breeze electrical engineering set, the solar cell array is affect by the outside factor, changing the scope to pare greatly, as a result turned the energy of generate electricity the system management to also put forward the higher request towards control and excellently. This text aims at the movement efficiency and credibility’s that the characteristics of the system movement designs one energy management system( energy management system, brief name EMS) to raise the system. posing of the systems This text with the south science and engineering university dispersion type wind force a solar energy of the new energy center admixture generates electricity the system for study the view, the structure diagram of the system, such as 2 － 1 of figure 1 show: May known by the chart 21, the system includes following several parties: The wind power machine and its controller: Total 15KW / sets of the biggest exportation power of the breeze machine, the wind force machine generates electricity the controller to make the wind force machine been placed in the biggest power to output the appearance always. Solar cell and its electricity generation controller: The altogether 5 groups, solar cell each group of peaks tile 3 k W, the solar energy electricity generation controller causes the solar cell array throughout to be at the maximum work rate output condition. The data collects the system:( the data acquires the system, the brief name DAS)Used for the electric voltage, the load power that collects to examine the solar cell exportation power, the wind power machine to output the power, the system direct current part, and circulate the relevant information to the system that collect, providing the energy management system to carry on the analytical processing. The energy manages the system: collect each function of system unit movement parameter that system provide according to the data, carry out the valid management to the system and controls. Buffer electric capacity: carry out parts of electric voltages of the system direct current steady. Load and inversion: The new energy center load classification, a kind of load is a load which the energy center work and the experiment must guarantee。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 an
