【正文】 n 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 。 EMBED 和 EMBED give or get an electric shock the switch control to change the quantity for the city respectively and two the types load of provide the rate, this text define EMBED 、 EMBED for the switch function, take the value 0 or 1。 When the renewable energy cannot satisfy the basic load request, in fully uses the renewable energy under the premise, is insufficient partially carries on the suitable supplement by the city electricity, takes the system the biggest load is 750 kW. In the power supply system, the system electricity generation and the load active power balance, is the system safe stable movement essential condition. Because the system load is provides by the Divulgate after the inversion, the DC voltage stable direct influence system provides the electrical energy to the load the quality, takes the system direct current EMBED voltage in here to control for the system the quantity, and takes its operating region is 192 V 240V, chooses 216 V for the direct ponent rated voltage. In order to does not make the system the structure too to be plex, processing did not consider in here to the accumulator cell. Namely energy management system management system structure drawing like chart 2 – 2 show: EMBED , EMBED , EMBED , EMBED and EMBED difference for female line electric voltage, exportable and biggest power in the wind force machine, exportable and biggest power, system in the solar cell array of the direct current of the system a the type load the power and two loads needed need of power。 Two kind of loads are the electrical energies which energy center ancillary facilities and so on greenhouse control needs, when the renewable energy output electrical energy has the unnecessary energy, only then invests load. The system load and the direct ponent connection is, the direct current side which realizes through the inversion after PWM inversion, transforms for the voltage is constant, the profile good exchange electrical energy, provides for the load. The city gives or get an electric shock the controller: When can the electricity that renewable energy provide can satisfy a load of system need, giving or get an electric shock from the city to make the plement。Energy Management System of Admixture Electricitygenerating 1. One preface The admixture that wind force and solar cells generate electricity to constitute generates electricity the system and is called the breeze/ light to repair the system with each other, all having some mon weakness because of the breeze and solar energies, such as the energy density low, the stability is bad and is subjected to the weather influence not to continue, have the strong weak conjugation, solar energy of seasonal to interrupted etc. day and night. Be generate electricity by the wind force and solar energy respectively to the power supply, the credibility of its power supply lowers consumedly. The wind energy, solar energy has to repair sex with each other certainly, if the sun light of daytime is strong, the night breeze is many, the summer sunshine good, the breeze is weak。 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 se
