The embodiment of the invention provides a light storage regulation and control method, as shown in fig. 1, comprising the following steps:
step S1: building a building light storage direct current networking system.
In a specific embodiment, photovoltaic and energy storage devices of the building industry are distributed, and an associated management and control system is not used, so that unified management and control and scheduling of energy sources are inconvenient. In order to solve the problems, the embodiment builds a novel building light storage direct current networking system, namely, renewable energy sources, energy storage and user grading loads are integrated.
Specifically, as shown in fig. 2, the building light storage dc networking system includes: photovoltaic array, photovoltaic DC/DC converter, commercial building load, energy storage battery, charger, central controller and AC/DC bidirectional converter. The photovoltaic array is connected to the DC bus through a photovoltaic DC/DC converter, and provides charging power for commercial building loads through a charger, and the rest of the photovoltaic power is stored in an energy storage battery or fed to a power grid through a photovoltaic AC/DC bidirectional converter. The central controller is used for monitoring and controlling the photovoltaic DC/DC converter, the AC/DC bidirectional converter and the charger, and realizing maximum photovoltaic power tracking, bidirectional electric energy flow and on-demand regulation of charging power. Wherein the energy storage battery is not shown in fig. 2.
Step S2: based on the building light storage direct current networking system, a control strategy under a spontaneous self-use mode, a time period charging and discharging mode, a grid-connected mode and a peak clipping and valley filling mode is formulated.
In one embodiment, the control strategy in the autonomous mode includes the following: as shown in fig. 3 (a), the solar photovoltaic array power generation preferentially supplies commercial building loads, the excess electricity charges the energy storage battery, and if the battery reaches maximum charge power, the remaining electricity feeds the grid without triggering a maximum grid limit. As shown in fig. 3 (b), at night when the photovoltaic array does not generate electricity, the building light-storage direct-current networking system is automatically switched to an energy storage battery power supply mode, the energy storage battery is preferentially used for supplying commercial building loads, and if the energy storage battery is insufficient in power, the power grid and the energy storage battery are simultaneously used for supplying commercial building loads. As shown in fig. 3 (c), when the photovoltaic array is not sufficiently generating during the daytime, the energy storage battery starts to discharge, and the photovoltaic array and the energy storage battery are simultaneously supplied to commercial building loads. As shown in fig. 3 (d), during the day when the photovoltaic array and the energy storage battery are not sufficiently powered, electricity will be taken from the grid, and the grid, the photovoltaic array and the energy storage battery are simultaneously supplied to commercial building loads.
Further, the control strategy in the time period charging and discharging mode comprises the following steps: as shown in fig. 4 (a), in the charging period, the building light-storage dc networking system charges the energy storage battery, electricity is preferentially taken from the photovoltaic array, if the photovoltaic array is insufficient in power generation, electricity is taken from the power grid, after the electric quantity of the energy storage battery reaches the charging stop residual capacity, the energy storage battery is charged only through the photovoltaic array, at the moment, the energy storage battery is not discharged, and the photovoltaic is normally output, so that the energy storage battery can be charged. As shown in fig. 4 (b), the self-service is performed spontaneously during the discharge period. And the energy storage battery is not discharged outside the time period, the photovoltaic is normally output, and the energy storage battery can be charged.
Further, the control strategy in the grid-connected mode comprises the following steps: after the grid-connected point function is set, the building light storage direct current networking system takes electricity from the power grid or feeds electricity to the power grid at constant power within a first preset time period. As shown in fig. 5 (a), after the grid-tie function is set, the building optical storage dc networking system takes electricity from the power grid at a constant power, and the electricity is supplied to commercial building loads and charges the energy storage battery. As shown in fig. 5 (b), after the grid-connected point function is set, the photovoltaic array generates electricity, and the energy storage battery discharges, and the electric energy is fed to the power grid while being supplied to the commercial building load. And executing normal grid-connected logic outside the first preset time period.
Further, the control strategy in the peak clipping and valley filling mode comprises the following steps: and in a second preset time period, when the electric power taken by the building light-storage direct-current networking system is larger than a peak value or lower than a valley value, the building light-storage direct-current networking system enables the electric meter power to be lower than the peak value or higher than the valley value through charge and discharge, and when peak clipping and valley filling are not triggered, the system output and input are 0. As shown in fig. 6 (a), in the peak clipping period, when the power of the building optical storage dc network system is greater than the peak value, the power of the power grid is reduced, and the power supplied by the photovoltaic array and the energy storage battery is increased, so that the power of the electric meter is lower than the peak value. As shown in fig. 6 (b), in the valley filling period, when the power taken by the building light-storage dc network system is lower than the valley value, the power taken by the power grid is increased, the photovoltaic array is stopped to generate electricity, and the energy storage battery is charged at the same time, so that the power of the electricity meter is higher than the valley value. And executing normal grid-connected logic outside the second preset time period.
In the embodiment of the invention, the priority of the control strategy is as follows from high to low in sequence: a control strategy in a peak clipping and valley filling mode, a control strategy in a grid-connected point mode, a control strategy in a time period charging and discharging mode and a control strategy in a spontaneous self-use mode. The first preset time period and the second preset time period are set according to each control strategy.
Step S3: and executing a control strategy corresponding to the operation condition according to the operation condition of the building light storage direct current networking system and the priority of the control strategy.
In a specific embodiment, according to the operation condition of the building light storage direct current networking system, a control strategy under the operation condition is selected, and then the selected control strategy is sequentially executed according to the priority of the control strategy, so that the problem of maximum utilization of the building low-capacity light storage is solved.
