Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the application provides a power distribution method of a micro-grid central controller. Fig. 1 is a schematic flow chart of a power distribution method of a microgrid central controller in one embodiment. Referring to fig. 1, the method for distributing power to the microgrid central controller includes steps 102 to 108:
and 102, detecting the residual electric quantity of the energy storage device of the microgrid if the fault of the main power grid is detected.
The micro-grid small power generation system generally stores the converted electric energy in an energy storage device, and then the micro-grid central controller controls the energy storage device to supply power to each standby electric load. The main grid may be a national large power generation and distribution system.
In particular, the microgrid energy storage means may be a storage battery. Specifically, the electric loads to be used may be household electric loads such as an air conditioner, a refrigerator, a washing machine, a television, and the like, or the electric loads to be used may be electric loads to be used in an office building such as a computer, a server, and the like, or the electric loads to be used may be respective charging piles in a charging station.
And 104, if the residual electric quantity of the energy storage device of the microgrid is lower than a preset electric quantity threshold value, acquiring the electricity utilization information of each standby electric load.
Specifically, the electricity consumption information of each of the inactive electric loads includes power outage influence information of each of the inactive electric loads, work item information of each of the inactive electric loads, and/or an electricity charge pricing of each of the inactive electric loads, and the like. The power outage influence information may be information of a degree to which the standby electrical load is influenced by the power outage at the time of the power outage.
In one embodiment, if a fault of a main power grid is detected and if the remaining power of an energy storage device of the microgrid is lower than a preset power threshold, a priority distribution instruction is generated, and power utilization information of each standby power load is obtained according to the priority distribution instruction.
And 106, distributing power distribution priority for each standby electric load according to the power utilization information of each standby electric load.
For example, a power outage has a large impact and the priority of the power outage is higher; the work items of the standby electrical loads are of a higher importance and the assigned priority is higher. Specifically, the electric loads to be used having a high priority may preferentially distribute power.
And 108, distributing power for each standby electric load by using the energy storage device of the micro-grid according to the power distribution priority of each standby electric load.
For example, a large number of users in an office building only have one photovoltaic system, and when the storage battery of the photovoltaic system is insufficient, the main power grid fails, and power is preferentially distributed to important standby electric loads. In other embodiments, if the main power grid is recovered to be normal, the main power grid can be switched to be connected to supply power to each standby electric load, and the priority can be not considered.
In one embodiment, the loads to be used are charging piles in the charging station; each charging pile is provided with an integrated control intelligent charging management unit. The step of acquiring the electricity utilization information of each of the electric loads to be used includes: establishing communication connection between the microgrid central controller and each comprehensive control intelligent charging management unit; and acquiring the residual chargeable electric quantity of each charging pile, and acquiring the electric charge pricing of the corresponding charging pile from each comprehensive control intelligent charging management unit by utilizing the micro-grid central controller. The comprehensive control intelligent charging management unit is internally provided with an electric charge pricing strategy of a corresponding charging pile, and calculates the electric charge of a charging user according to the electric charge pricing strategy.
The step of allocating the power distribution priority to each of the inactive electric loads according to the power consumption information of each of the inactive electric loads includes: and distributing power distribution priority for each charging pile according to the electric charge pricing of each charging pile and the residual chargeable electric quantity of each charging pile.
In this embodiment, each power consumption information of the electric load for use is each electric charge pricing of filling electric pile and each remaining chargeable electric quantity of filling electric pile, can fill electric pile distribution priority for each according to electric charge pricing of filling electric pile and the remaining electric quantity of filling electric pile. For example, the charging pile with high electric charge price can be a charging pile for charging the VIP user, when the charging pile for charging the VIP user is charged, queuing is not needed, the electric charge price is high, and the power distribution priority of the charging pile can be improved so as to avoid influencing the charging of the VIP user. If the chargeable electric quantity of filling electric pile is less than other electric piles that fill, can improve this distribution priority who fills electric pile.
Further, the step of allocating a power distribution priority to each charging pile according to the electricity charge pricing of each charging pile and the remaining chargeable electric quantity of each charging pile includes steps 202 to 204:
YCi＝a×CFi/∑CF+b×CSi/∑CS；i＝1，2····N；
wherein, YCiDistribution factor for the ith charging pile, CFiPricing the electricity charge for the ith charging pile, a andb is the corresponding weight coefficient, N is the total number of charging piles, and a + b is 1,0<a<1,0<b<1；∑CFSum of charging costs, Σ C, for each charging pileSThe sum of the remaining chargeable electric quantity of each charging pile.
In other embodiments, the first predetermined calculation model may also be;
YCi＝a×CFi+b×CSi；i＝1，2····N；
wherein, YCiDistribution factor for the ith charging pile, CFiCharging the electricity fee of the ith charging pile, a and b are corresponding weight coefficients, N is the total number of the charging piles, and a + b is 1,0<a<1,0<b<1。
And 204, comparing the sizes of the power distribution factors of the charging piles, and distributing power distribution priorities to the charging piles according to the descending order of the power distribution factors of the charging piles.
For example, the power distribution factor Y of charging pile number 1 in the charging stationC1Power distribution factor Y higher than number 2 charging pileC2And then the distribution priority of the No. 1 charging pile is higher than that of the No. 2 charging pile.
Specifically, a is greater than b. Compared with the residual chargeable electric quantity of each charging pile, the weight coefficient occupied by the electric charge pricing of each charging pile is set to be larger, and the user requirements are considered more.
In one embodiment, the micro-grid is applied to a building, and each electricity load to be used is an electricity load in each household user; the step of acquiring the electricity utilization information of each of the electric loads to be used includes: acquiring power failure influence information of each family user; the step of allocating the power distribution priority to each of the inactive electric loads according to the power consumption information of each of the inactive electric loads includes: and distributing power distribution priority for the power load of each household user according to the power failure influence information of each household user. Specifically, the power outage influence information of the home user may be information of a degree of influence of the power outage on the home user at the time of the power outage. Specifically, the power outage influence information of each household user includes the length of stay of each household user and the power load level of each household user.

For another example, in a certain hospital, the 1 st floor is an outpatient department, the 2 th to 4 th floors are courtyards, and the 5 th floor is an operating room, so that it is obvious that the electricity load level of the 5 th floor is higher than that of other household users, and the micro-grid can be accessed to preferentially distribute electricity for the 5 th floor.
Further, the step of allocating power distribution priority to the power load of each household user according to the power failure influence information of each household user comprises steps 302 to 304:
YJi＝c×JSi/∑JS+d×JFi/∑JF；i＝1，2····N；
wherein, YJiThe length of stay for the ith home subscriber, JSiThe length of stay for the ith home subscriber, JFiThe electricity load grade of the ith household user, wherein the higher the electricity load grade is, JFiThe larger; c and d are corresponding weight coefficients, N is the total number of the home users, and c + d is 1,0<c<1,0<d<1；∑JSTotal length of stay, sigma J, for each home userFIs the sum of the user load levels of the individual home users.
In other embodiments, the second preset calculation model may also be:
YJi＝c×JSi+d×JFi；i＝1，2····N；
wherein, YJiThe length of stay for the ith home subscriber, JSiThe length of stay for the ith home subscriber, JFiThe electricity load grade of the ith household user, wherein the higher the electricity load grade is, JFiThe larger; c and d are corresponding weight coefficients, N is the total number of the home users, and c + d is 1,0<c<1,0<d<1。
And 304, comparing the sizes of the power distribution factors of the household users, and distributing power distribution priorities to the household users according to the sequence from large to small of the power distribution factors of the household users.
For example, the distribution factor Y of a first floor householdJ1Distribution factor Y greater than first floor householdJ2And the power distribution priority of the first floor family users is higher than that of the second floor family users.
Specifically, c < d. Compared with the length of time of the household user's residence, the weight coefficient occupied by the electricity load grade of the household user is set to be larger, and the proportion of the electricity load grade of the household user in the distribution priority can be improved.
According to the power distribution method of the microgrid central controller, when the main power grid fails and the residual power of the energy storage device is lower than the preset power threshold, the power distribution priority of each standby electric load is considered, the energy storage device of the microgrid is accessed to distribute power for each standby electric load according to the power distribution priority of the standby electric load, the power consumption load of the energy storage device of the microgrid can be reduced, and the standby electric load which is preferentially distributed can be supplied with power for a long time.
