【正文】 read 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. 2. 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: 2 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。 namely chase the city to give or get an electric shock the conduct and actions back up power supply, pass bine the controller to control the devotion and the excision of the city electricity. In the wind power, the solar energy and the load constitution electricity generation, uses electricity in the system, as a result of the wind speed, the sunshine intensity and other climatic conditions changes, the wind electrical machinery, the solar cell array output and the load power all has paratively wide range the undulation, thus set the very high request to the energy management system management system. This article in view of is being constructed a South China technical University new energy center disperser like wind power solar energy mix generating system, has designed an energy management system management system, according to the system electricity generation, the load uses electricity the condition, the management system management system power supply pattern, nimbly adjusts each part to supply the electric quantity the proportion. The energy management system management system is bigger than the load demand when the renewable energy, shuts off the partial solar energies, the wind electrical machinery。 4 WK and PVK output to make use of the coefficient and the solar cell arrays to output the utilization for the wind force machine of the system with respectively, namely count to amount it with the wind force machine for the set that the wind
