Embodiment 1
[0033] Management methods for connecting distributed power sources and microgrids to the main grid, such as figure 1 , figure 2 shown, including the following steps:
[0034] Step A, power grid demand response or daily dispatch: the main grid issues power supply demand or daily dispatch work to form a demand response;
[0035] Step B. Response to demand: The formed demand response is published to the micro-grid, and the micro-grid responds to the demand;
[0036]Step C, strategy formulation: simulate the microgrid system, first adjust the equipment parameters of each micropower system in the microgrid, such as the stator equipment, inverter equipment, and frequency converter equipment of the synchronous power generation system, such as the photovoltaic power generation system. Equipment parameters such as battery panels and inverters are adjusted, and then according to the parameter adjustment value, it corresponds to the parameter impact table, and combined with the weathe...
Embodiment 2
[0044] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, step A, power grid demand response or daily dispatch: the main power grid issues power supply demand or daily dispatch work to form a demand response;
[0045] Step B. Response to demand: The formed demand response is published to the micro-grid, and the micro-grid responds to the demand;
[0046] Step C, strategy formulation: Simulate the micro-grid system, collect variable parameters such as component temperature, ambient temperature, irradiance, and wind speed, and collect fixed parameters including micro-power equipment, and use programs to arrange and combine them to form a parameter impact table. In each micro-power system of the micro-grid, such as the stator equipment, inverter equipment, and frequency converter equipment of the synchronous power generation system, the equipment parameters are adjusted, and equipment parame...
Embodiment 3
[0052] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, further, in order to better realize the present invention, the strategy formulation is divided into manual mode strategy and automatic mode strategy. Under the manual mode strategy, the microgrid system is subjectively configured by the operator, that is, the subjective setting strategy, So as to form a strategy, and then save and execute the strategy; under the automatic mode strategy of the micro-grid system, the micro-grid system automatically detects the dynamic library according to the temperature, wind direction, radiation and other weather environment information, performs similar matching of parameter values, and automatically adjusts each micro-grid Configure equipment parameters to form a strategy to make the microgrid system operate in the optimal mode. Through the environmental collection data such as ambien...
