Based on simulation parameter, the online regulation of energy method of honourable hydrogen comprehensive energy system is analyzed.Electrolytic cell
Setting：It is 1.5kW, rated power 4kW that minimum technology, which is contributed,.Fuel cell is arranged：Rated power is 2.5kW.Hydrogen container is set
It sets：Hydrogen storage is independent parallel using double tanks, each other standby mode, tank volume 0.5m3, 1#Storage tank initial pressure be 0.5Mpa, 2#
Storage tank initial pressure is 0.4Mpa, upper pressure limit 1.0Mpa, low pressure limit 0.3Mpa, hydrogen container running temperature reduction to 25
DEG C, wind speed and irradiation intensity setting are as depicted in figs. 1 and 2 respectively, allow grid-connected power setting as shown in figure 3, electrolyzer temperature
It is as shown in Figure 4 that curve is set.Fig. 5 is the grid-connected changed power curve of permanent magnet direct-driving aerogenerator group, as seen from the figure, Wind turbines
Power curve and wind speed setting variation tendency are almost the same.Fig. 6 is grid-connected photovoltaic changed power curve, as seen from the figure, photovoltaic work(
Rate curve and irradiation intensity setting variation tendency are almost the same.Fig. 7 is electrolytic cell changed power curve, as seen from the figure, electrolytic cell
Power 4kW fluctuating changes between minimum technology output 1.5kW and rated power, changing value are calculated according to online regulation of energy strategy
.Fig. 8 is fuel battery power change curve, as seen from the figure, fuel battery power fluctuating change between 0-2.5kW.Fig. 9 is
1#With 2#Hydrogen container pressure history selects 1 first as seen from the figure#Storage tank carries out filling tank, when 1#Storage tank reaches upper pressure limit
When 1.0Mpa, start 2# storage tanks.Figure 10 is system grid connection changed power curve, as seen from the figure, in the online regulation of energy plans of this chapter
Under slightly, grid-connected power substantially can be by power setting curve motion, only in 110m-175m periods and 375m-400m period systems
Power does not press setting Power operation, and the 110m-175m periods, system reached since honourable general power is more than electrolytic cell rated power 4kW
To the absorption excess power upper limit, therefore there is grid-connected power and be more than the setting Power operation period, the 375m-400m periods are set due to power
The system vacancy power of definite value and honourable general power is more than fuel cell rated power 2.5kW, therefore grid-connected power occurs less than setting
Determine the Power operation period.
