First embodiment referring to fig. 1, a method for adjusting a control strategy of a photovoltaic ice storage air conditioner includes the following steps:

S11: acquiring the current period running condition of an air conditioner and the current period power generation, power utilization and power storage conditions of a photovoltaic system;

S12: when the current period ice melting control strategy of the air conditioner is unreasonable according to the current period running condition, the next period ice melting control strategy is adjusted; when the current period photovoltaic power utilization control strategy is unreasonable according to the current period power generation, power utilization and power storage conditions, if the next period ice melting control strategy does not need to be adjusted, the next period photovoltaic power utilization control strategy is directly adjusted; and if the next period ice melting control strategy needs to be adjusted, adjusting the next period photovoltaic power utilization control strategy by combining the adjusted next period ice melting control strategy.

According to the photovoltaic ice storage air conditioner control strategy adjustment method provided by the embodiment of the application, when the current period ice melting control strategy is unreasonable according to the current period running condition, the next period ice melting control strategy is adjusted, because the power consumption of the air conditioner is changed after the next period ice melting control strategy is adjusted and before adjustment, if the photovoltaic system is controlled according to the original next period photovoltaic power consumption control strategy, the actual requirement is not met, and therefore the next period photovoltaic power consumption control strategy is adjusted according to the adjusted next period ice melting control strategy; in addition, when the current period power utilization control strategy is unreasonable directly according to the current period power generation, power utilization and power storage conditions of the photovoltaic system, the next period power utilization control strategy is also adjusted. According to the scheme, whether the ice melting control strategy of the current period and the electricity utilization control strategy of the current period are reasonable or not is judged according to the actual production running condition of the current period, and the ice melting control strategy of the next period and the photovoltaic electricity utilization control strategy of the next period are adjusted according to unreasonable places when the ice melting control strategy of the current period and the electricity utilization control strategy of the next period are unreasonable, so that the next period of the air conditioner can run efficiently, and the running cost and the energy consumption of the next period are reduced effectively.

In a second embodiment, as a supplementary explanation of the first embodiment, the present invention provides a specific method for adjusting a control strategy of a cool storage air conditioner by using light Fu Bing, which includes the following steps:

Firstly, recording the running condition of an air conditioner in the past day to obtain the running condition of the day, and the conditions of power generation, power consumption and power storage of a photovoltaic system, namely the conditions of power generation, power consumption and power storage in the day;

And judging whether the current day ice melting control strategy is reasonable according to the current day running condition, and judging whether the current day photovoltaic power utilization control strategy is reasonable according to the current day power generation, power utilization and power storage conditions.

And when the control strategy is unreasonable, the next-day ice melting control strategy and the next-day photovoltaic power utilization control strategy are adjusted.

The detailed flow of the ice melting control strategy diagnosis on the same day is shown in fig. 2, and comprises the following steps:

Step 1: it is first necessary to determine the time periods of peak, flat, valley of the price of electricity of one day, and the time period when the peak of the load occurs. The time periods of peak, flat, valley of the electricity price are obtained from the authorities of the power supply office, for example. The load peak value is the load of the maximum ice melting and cooling capacity of building load demand not less than the full-open and high-efficiency running cooling capacity of the water chilling unit and the full-open and high-efficiency running cooling capacity of the double-station unit.

Step 2: preferentially diagnosing the ice melting control strategy of the load peak time period, secondly diagnosing the electricity price peak period except the load peak time period, and finally diagnosing the electricity price flat period except the load peak time period; namely, the load demand is preferentially met, and in the non-load peak time period, the rationality of the whole time period can not be considered when the ice melting control strategy or the electricity utilization control strategy is adjusted, so that the pricing of the power supply mechanism for each time period is combined, and the electricity price peak section, the electricity price flat section and the electricity price valley section are divided. After the demand is preferentially ensured, the ice melting control strategy of the electricity price peak section is preferentially adjusted from the economic point of view, and then the electricity price flat section is obtained.

Step 3: in the peak load time period, firstly diagnosing whether the ice melting and cooling quantity in the hour reaches the maximum or not, if not, considering that the ice melting and cooling quantity is not fully utilized, improving the energy consumption of a system, and judging that the ice melting control strategy in the current day is unreasonable; if yes, go to step 4;

Step 4: diagnosing whether the running load of the water chilling unit is above the high-efficiency area or not, if not, considering that the water chilling unit runs below the high-efficiency area, so that the double-working condition unit bears more load, the system is not energy-saving in running, and the ice melting control strategy is unreasonable in the same day; if yes, go to step 5; the high-efficiency area of the unit, namely, the operation load area when the unit operates most in power saving is obtained by combining the performance curve of the unit; the trend of the unit performance curve is a parabola with low two ends and high middle, the abscissa is the unit load rate, the ordinate is the COP (coefficient of performance) of the unit with the ratio of refrigerating capacity to power consumption, the larger the COP is, the better the unit energy efficiency is, the load rate is the ratio of the current cooling capacity to the maximum cooling capacity of the unit, 100% load rate is the full-load running of the unit, but when the COP of the unit is the maximum, the load rate is less than 100%, namely the running load of the unit is not full-load, and because of factors such as measurement errors, the high-efficiency area of the high-efficiency running of the unit is generally represented by a load rate interval, and each curve is different because of the high-efficiency area of the inlet water temperature and the outlet water temperature. For example, if the high-efficiency area is a load factor of 40% -60%, the high-efficiency area is above the load factor of more than 60%, and the high-efficiency area is below the load factor of less than 40%.

Step 5: diagnosing whether the running loads of the double-working-condition unit are above the high-efficiency area and the high-efficiency area, if not, considering that the loads born by the water chilling unit are excessive, and if the water chilling unit is running above the high-efficiency area and even fully loaded, the energy consumption of the system is increased, and the ice melting control strategy in the same day is unreasonable; if yes, the current day ice melting control strategy of the load peak time period is considered reasonable;

Step 6: in the electricity price peak section except the load peak time section, firstly diagnosing whether the ice melting and cooling quantity in the hour reaches the maximum or not, if not, considering that the ice melting and cooling quantity is not fully utilized, the energy consumption of the system is improved, and the ice melting control strategy in the day is unreasonable; if yes, go to step 7;

Step 7: diagnosing whether the running load of the started water chilling unit is in a high-efficiency area, if so, entering a step 8; if not, go to step 9;

step 8: diagnosing whether the running loads of the opened double-station unit are in the high-efficiency area, if so, considering that the ice melting control strategy in the current day of the time period is reasonable; if not, go to step 10;

Step 9: diagnosing whether the running load of the started water chilling unit is below the high-efficiency area, if not, considering that the water chilling unit runs above the high-efficiency area, and carrying too much load, and unreasonable ice melting control strategy in the same day; if yes, go to step 11;

Step 10: diagnosing whether the running load of the opened double-working-condition unit is below the high-efficiency area, if not, considering that the data at the moment is wrong, and directly outputting the ice melting control strategy at the same day is unreasonable; if yes, go to step 11;

step 11: the ice melting and cooling quantity is reduced, so that the started water chilling unit or the double-station unit can be operated in a high-efficiency area;

Step 12: in the level section except the load peak time section, firstly, a set value of ice melting and cooling quantity is obtained, the set value of ice melting and cooling quantity=adjustable coefficient is multiplied by a coefficient of 1.05-1.1 when the total ice melting and cooling quantity of the day is equal to the current day level section, and the adjustable coefficient is obtained according to the comparison of a current day predicted weather parameter and a current day weather predicted parameter and the comparison of a current day load demand and a current day load demand, and according to the weather predicted result, the moment of bad working condition and large load demand is multiplied by a coefficient of 0.95-0.9.

Step 13: diagnosing whether the ice melting and cooling capacity is smaller than or equal to the load demand, if not, the ice melting and cooling capacity is reduced as a diagnosis result; if yes, go to step 14;

Step 14: diagnosing whether the running loads of the started water chilling unit are in the high-efficiency area, if so, entering a step 15; if not, go to step 16;

Step 15: diagnosing whether the operation loads of the started double-station unit are in the high-efficiency area, if so, considering that the ice melting control strategy in the current day of the time period is reasonable; if not, go to step 17;

step 16: diagnosing whether the running load of the started water chilling unit is below the high-efficiency area, if so, entering a step 18; if not, go to step 19;

step 17: diagnosing whether the running loads of the opened double-station unit are in the high-efficiency area, if so, entering a step 18; if not, go to step 19;

step 18: diagnosis results: the ice melting and cooling quantity is required to be increased at the moment, so that the quantity of water chilling units and double-station units which need to be started is reduced; if the ice storage quantity can not meet the ice melting and cooling requirements at other moments in the same period, the ice melting and cooling quantity is reduced, so that the started water chilling unit and the double-station unit operate in the high-efficiency area;

Step 19: diagnosis results: the ice melting and cooling quantity is required to be increased at the moment, so that the started water chilling unit and the double-station unit operate in an efficient interval; if the ice storage quantity can not meet the ice melting and cooling requirements at other moments in the same period, the starting quantity of the water chilling unit and the double-station unit is increased;

The diagnosis of the ice melting control strategy is that the ice melting and cooling quantity is controlled according to the maximum ice melting and cooling quantity of the hour in the peak load time period and the peak electricity price period; in the level section except the peak load time section, the ice melting and cooling capacity is controlled according to a set value; according to the diagnosis results of each period, the adjustment strategy and the adjustment amplitude of the ice melting and cooling quantity are recorded, and then the ice melting control strategy of the next day is guided by combining weather prediction results (different weather can lead to the running condition of the unit).

The detailed flow of the photovoltaic power generation diagnosis is shown in figure 3:

step 21: firstly, determining an electricity peak valley time period and a photovoltaic power generation time period in the current season;

Step 22: diagnosing whether a part of time period exists in the photovoltaic power generation time period, wherein the storage battery can be fully full of the residual quantity of the photovoltaic power generation, and if so, considering that the photovoltaic power generation is sufficient; if not, the photovoltaic power generation is considered to be insufficient;

Step 23: if the photovoltaic power generation is sufficient, diagnosing whether the storage battery stores electricity by using a mains supply in the early morning electricity price valley section, if so, determining that the energy storage strategy is unreasonable in the day, and storing electricity by using the photovoltaic power generation allowance; if not, go to step 24;

Step 24: diagnosing whether a power price peak section adopts a power supply strategy of 'using photovoltaic directly for priority and using a storage battery for discharging secondly', if not, the power utilization operation strategy of the current day is unreasonable; if yes, go to step 25;

Step 25: the method comprises the steps of diagnosing whether a power supply strategy of 'using photovoltaic direct supply preferentially, using a storage battery to discharge secondly and using a commercial network direct supply finally' is adopted in a level section, and if so, considering that a current power utilization operation strategy is reasonable; if not, the current power consumption operation strategy is considered unreasonable;

Step 26: if the photovoltaic power generation is insufficient, diagnosing whether the storage battery stores power by using a mains supply in the early morning electricity price valley section, if not, considering that the energy storage strategy is unreasonable in the day, and storing power by mainly using the mains supply directly, wherein part of electric quantity can store power by using the photovoltaic power generation allowance; if yes, go to step 27;

Step 27: diagnosing whether a power supply strategy of 'using photovoltaic direct supply preferentially, using a storage battery to discharge and using a commercial network direct supply finally' is adopted at the peak section of the electricity price, and if not, judging that the current power utilization operation strategy is unreasonable; if yes, go to step 28;

Step 28: the method comprises the steps of diagnosing whether a power supply strategy of 'using photovoltaic direct supply preferentially and using a storage battery for discharging secondly' is adopted in a level section, and if not, judging that a daily power utilization operation strategy is unreasonable; if yes, the current power consumption operation strategy is considered to be reasonable;

According to the deviation of the actual meteorological parameters and the predicted meteorological parameters on the diagnosis day, the diagnosis result and the meteorological prediction result on the next day, the energy storage strategy and the electricity utilization strategy on the next day can be guided and optimized;
