Example two
The second embodiment is optimized based on the above embodiments. In this embodiment, utility sub-platform 120 is further configured to: determining the power storage condition of each power device in the energy management system 110 according to the processed power data, and transmitting the power storage condition to the energy management system 110, so that the energy management system 110 schedules the electric quantity of each power device according to the power storage condition.
In this embodiment, the utility grid sub-platform 120 may transmit the acquired power storage condition of each power device to the energy management system 110, so that the energy management system 110 may perform power scheduling.
The plurality of power devices share the alternating current bus so as to directly schedule the electric quantity among the power devices. The problem of electric quantity conversion during electric quantity scheduling among all the electric power equipment can be avoided by using the alternating-current bus. For example, 380v alternating current buses can be shared among the power devices for power scheduling.
Further, the energy management system 110 is specifically configured to: if the electricity storage condition is that the electricity storage amount of the photovoltaic assembly is higher than a first preset electricity amount, outputting the electricity amount generated by the photovoltaic assembly to a public power grid, an energy storage device or a charging pile; if the electricity storage condition is that the electricity storage amount of the energy storage device is lower than a second preset electricity amount, acquiring redundant electricity amount in the photovoltaic assembly to charge the energy storage device; if the electricity storage condition is that the electricity storage amount of the energy storage device is higher than a third preset amount of electricity, outputting the surplus electricity of the energy storage device to a public power grid or a charging pile; if the electricity storage condition is that the electricity storage amount of a charging pile is lower than a fourth preset electricity amount, acquiring redundant electricity amounts of the public power grid, the photovoltaic module and the energy accumulator to charge the charging pile; if the electricity storage condition is that the electricity storage amount of the charging pile is higher than a fifth preset amount of electricity, outputting the surplus electricity of the charging pile to the public power grid or the energy accumulator;
the first preset electric quantity, the second preset electric quantity, the third preset electric quantity, the fourth preset electric quantity and the fifth preset electric quantity are different electric quantities.
In this embodiment, the first preset electric quantity may be the lowest electric quantity of the preset photovoltaic module, and preferably, the lowest electric quantity may be 0, that is, after the photovoltaic module generates the electric quantity, all generated electric quantities may be used as surplus electric quantities for charging the public power grid, the energy storage device or the charging pile. The redundant electric quantity can be transmitted to the electric power equipment needing to be charged through the inverter, the photovoltaic cabinet combining network and the power distribution equipment.
In this embodiment, the second preset electric quantity can be the lowest electric quantity of the preset energy storage device, and when the current electric quantity of the energy storage device is lower than the lowest electric quantity of the energy storage device, the energy storage device needs to be charged, and then the redundant electric quantity of the photovoltaic module can be scheduled from the photovoltaic module to charge the energy storage device. It should be noted that, when the energy storage device is charged, the excess electric quantity of the photovoltaic module needs to be transmitted to the energy storage device through the energy storage converter.
In this embodiment, the third predetermined amount of electricity may be a critical discharge value of the energy storage device, and it is understood that other electrical devices may be charged if the amount of electricity stored in the energy storage device is higher than the critical discharge value. For example, if the stored energy in the energy storage device is higher than 50%, more than 50% of the stored energy may be used as the surplus energy of the energy storage device, and the surplus energy of the energy storage device may be used to charge the public power grid or the charging pile. When the energy storage device charges other electric devices, the excess electric quantity in the energy storage device needs to be transmitted to other electric devices through the energy storage converter.
In this embodiment, the fourth preset electric quantity may be the lowest electric quantity of the preset charging pile, and for example, if the electric storage quantity of the charging pile is less than 10% of the total electric quantity of the charging pile, the surplus electric quantities of other electric power devices need to be scheduled to charge the charging pile. It should be noted that when the photovoltaic module charges the charging pile, the redundant electric quantity of the photovoltaic module can be transmitted to the charging pile through the inverter and the photovoltaic grid-connected cabinet; when the charging pile is charged by the energy accumulator, the redundant electric quantity of the energy accumulator can be transmitted to the charging pile through the energy storage converter; when public power grid charges charging pile, can pass through distribution equipment with public power grid's electric energy and transmit to charging pile.
In this embodiment, the fifth preset electric quantity may be a preset critical discharge value of the charging pile, and it may be understood that other electric devices may be charged when the electric energy stored in the charging pile is higher than the critical discharge value. For example, if the stored power of the charging pile is higher than 10%, more than 10% of the stored power may be used as the surplus power of the charging pile for charging the utility grid or the energy storage device. It should be noted that when the charging pile charges the public power grid, the redundant electric quantity of the charging pile can be transmitted to the public power grid through the power distribution equipment; when charging the energy storage device, the charging pile can transmit the redundant electric quantity of the charging pile to the energy storage device through the energy storage converter.
The electric power platform provided by the second embodiment of the invention embodies the process of carrying out electric quantity scheduling on each electric power device. By using the method, the electric quantity scheduling can be realized by the AC charging pile carrying the V2G technology in cooperation with other power equipment, the power consumption requirement in the peak period is met, the peak clipping and valley filling are realized, the power distribution and capacity increasing cost can be saved, the consumption of new energy is increased, the defect of the stability of photovoltaic power generation is overcome, and the method is an energy utilization mode of sustainable development.
