Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
As shown in fig. 1, the present invention provides a photovoltaic power generation and wind power generation integrated management system, including: the photovoltaic power generation equipment power generation monitoring module is used for monitoring the real-time power generation amount of the photovoltaic power generation equipment; the wind power generation equipment power generation monitoring module is used for monitoring the real-time power generation amount of the wind power generation equipment; the power consumption statistical module is used for monitoring the historical power consumption of the power utilization side in a historical time period and estimating the expected power consumption of the power utilization side in a selected time period when the selected time period is not reached according to the historical power consumption of the power utilization side in the historical time period; an energy storage device for storing electrical energy; and the power supply management module is used for initiating a power supply scheduling application to the off-grid power supply equipment when the sum of the real-time power generation amount of the photovoltaic power generation equipment and the real-time power generation amount of the wind power generation equipment is smaller than the expected power consumption amount in the selected time period, and the electric quantity of the energy storage equipment cannot cover the gap between the sum of the real-time power generation amount of the photovoltaic power generation equipment and the real-time power generation amount of the wind power generation equipment and the expected power consumption amount in the selected time period, wherein the power supply scheduling application comprises the gap and the difference between the electric quantities of the energy storage equipment.
In the embodiment of the invention, the electricity consumption statistical module estimates the expected electricity consumption in the selected time period according to the historical electricity consumption in the historical time period of the electricity utilization side in advance when the selected time period does not arrive. For example, if the estimated day is 7/month/1/day and the selected time period is 7/month/3/day of the year (i.e., the second day after the estimation), then the expected power usage on the 7/month/3/day may be estimated based on the historical power usage on each day in the same month of the previous year (e.g., the 7/month of the previous year). The expected power usage for 7 months and 3 days may be higher due to being in the summer. And then, the power supply management module calculates the sum of the real-time power generation amount of the photovoltaic power generation equipment and the wind power generation equipment and the expected power consumption to obtain an estimated power utilization gap. And if the electric quantity of the energy storage equipment cannot cover the power utilization gap at the moment, a power supply scheduling application is initiated to the off-grid power supply equipment in advance. The off-grid power supply equipment can make preparations for supplying power to the region in a supplementing way after receiving the power supply scheduling application. Here, the power utilization gap is calculated by using the real-time power generation amount of the photovoltaic power generation device and the wind power generation device, that is, the real-time power generation amount on the estimated day (i.e., 7 months and 1 days in the example) rather than the real-time power generation amount at the time of the selected time period, so that the power utilization gap of a certain time period occurring in the future is estimated by using the real-time power generation amount at an earlier time, and then the planning of power distribution is made in advance, so that the efficiency of power scheduling in a larger range including the local area is improved, the efficiency of power scheduling and distribution is also improved, and the needs of daily production and life are met.
Accordingly, if the sum of the real-time power generation amounts of the photovoltaic power generation equipment and the wind power generation equipment is larger than the expected power consumption amount in the selected time period, the power supply scheduling application is not required. If the sum of the real-time power generation amount of the photovoltaic power generation equipment and the wind power generation equipment is smaller than the expected power consumption amount in the selected time period, the power amount of the energy storage equipment can cover a gap between the sum of the real-time power generation amount of the photovoltaic power generation equipment and the real-time power generation amount of the wind power generation equipment and the expected power consumption amount in the selected time period, and power supply scheduling application is not needed.
The off-grid power supply equipment refers to power supply equipment in other areas except the local area power grid, and different off-grid power supply equipment can respond to power supply scheduling application every time so as to improve the efficiency of power distribution and utilization in a wider range including the local area.
In a preferred embodiment, the integrated management system for photovoltaic power generation and wind power generation further includes: the power consumption monitoring module is used for monitoring the real-time power consumption of the selected time period when the selected time period arrives at the power consumption side; the power supply management module is used for starting the energy storage device and the off-grid power supply device to supply power to the power utilization side when the sum of the real-time power generation amount of the photovoltaic power generation device and the real-time power generation amount of the wind power generation device is smaller than the real-time power consumption amount of the selected time period and the electric quantity of the energy storage device cannot cover the gap between the sum of the real-time power generation amount of the photovoltaic power generation device and the real-time power generation amount of the wind power generation device and the real-time power consumption amount in the selected time period.
The power supply scheduling application is made based on the estimated power utilization gap, and the estimated power utilization gap is estimated based on the current real-time power generation amount and the expected power consumption amount on the estimation day. However, when the selected time period actually occurs, the size of the gap between the real-time power generation amount and the real-time power consumption amount may change, so that the actual power consumption gap needs to be determined according to the sum of the real-time power generation amounts of the photovoltaic power generation device and the wind power generation device and the sum of the real-time power consumption amounts in the selected time period, and according to the actual power consumption gap, when the energy storage device cannot cover the actual power consumption gap, the energy storage device and the off-grid power supply device are used for supplying power. Correspondingly, when the electric quantity of the energy storage equipment can cover the actual power utilization gap, the energy storage equipment is only started to supply power.
In a preferred embodiment, in the integrated management system for photovoltaic power generation and wind power generation, the power supply management module is configured to control the photovoltaic power generation equipment and the wind power generation equipment to store energy to the energy storage equipment when a sum of a real-time power generation amount of the photovoltaic power generation equipment and a real-time power generation amount of the wind power generation equipment is greater than a real-time power consumption amount of the selected time period. And storing energy by using the energy storage equipment to prepare for supplementing power supply when an actual power utilization gap occurs. The embodiment is also beneficial to improving the utilization efficiency of resources and avoiding resource waste.
In a preferred embodiment, the integrated management system for photovoltaic power generation and wind power generation further includes: the light intensity detector is arranged in the installation environment of the photovoltaic power generation equipment and is used for detecting the real-time illumination intensity in the installation environment of the photovoltaic power generation equipment; the photovoltaic power generation equipment power generation monitoring module is used for determining theoretical power generation of the photovoltaic power generation equipment according to the preset relation between the power generation and the illumination intensity of the photovoltaic power generation equipment and the real-time illumination intensity, and prompting that the photovoltaic power generation equipment is in a fault state when the difference value between the theoretical power generation and the real-time power generation of the photovoltaic power generation equipment falls into a first preset interval.
Photovoltaic power generation equipment is often installed in outdoor environment, is difficult to discover the trouble.

If the real-time power generation amount of the photovoltaic power generation equipment is lower than the theoretical power generation amount, and the difference value between the theoretical power generation amount and the real-time power generation amount falls into a first preset interval, for example, the difference value between the theoretical power generation amount and the real-time power generation amount reaches 1-3% of the theoretical power generation amount, it is considered that the photovoltaic power generation equipment possibly has a fault and cannot generate power normally, at the moment, the power generation monitoring module of the photovoltaic power generation equipment can send prompt information, and managers can check and maintain the photovoltaic power generation equipment in time according to the prompt information.

Wind power generation equipment is often installed in outdoor environment, and is difficult to find out faults. Generally speaking, wind speed affects the power production of a wind power plant. The larger the wind speed, the larger the power generation of the wind power plant, and vice versa.

If the real-time power generation amount of the wind power generation equipment is lower than the theoretical power generation amount and the difference value between the theoretical power generation amount and the real-time power generation amount falls into a second preset interval, for example, the difference value between the theoretical power generation amount and the real-time power generation amount reaches 2-3% of the theoretical power generation amount, it is considered that the wind power generation equipment possibly has a fault and cannot generate power normally, at the moment, the power generation monitoring module of the wind power generation equipment can send prompt information, and managers can check and maintain the wind power generation equipment in time according to the prompt information.
In a preferred embodiment, in the integrated management system for photovoltaic power generation and wind power generation, the preset relationship between the power generation amount of the wind power generation equipment and the wind speed is a relationship established according to the historical power generation amount and the historical wind speed of the wind power generation equipment.
Specifically, historical power generation amount and historical wind speed data of multiple groups of wind power generation equipment can be obtained, and then a curve is drawn by using the data, so that the corresponding relation between the power generation amount and the wind speed of the wind power generation equipment is obtained.
