Step 2: and obtaining different scenes and probabilities of the day-ahead market price and the predicted photovoltaic output by adopting a time-homogeneous Markov chain (time-homogeneous Markov chain).
And step 3: solving the stochastic programming model based on the day-ahead market price, the different scenarios, and the probabilities thereof.
And 4, step 4: and controlling the running state of the intelligent building type virtual power plant according to the solved result.
In the embodiment, a certain modern commercial district is taken as an example to evaluate the effectiveness of the intelligent building type virtual power plant participating in the competitive bidding of the energy-frequency modulation market and realizing energy control at the same time. The load base line of a commercial district in summer and the virtual energy storage charging and discharging capacity of the air conditioner load in each period calculated according to the outdoor temperature and the air conditioner power are shown in fig. 2. The cost of unit frequency modulation capacity of virtual energy storage is 0.0015USD/kW, and the frequency modulation response rate is 80%. The installation capacity of the roof photovoltaic is 4MW, the marginal cost of power generation is 0.005USD/kWh, and the cost of participating in frequency modulation is 0.002 USD/kW. The successful bid probability of the virtual power plant participating in the frequency modulation auxiliary service market is 0.6, and the final called probability of the frequency modulation capacity is 0.7.
The bidding capacities of the intelligent building type virtual power plant participating in the upper and lower frequency modulation markets and the composition relationship thereof obtained by solving the data are shown in fig. 3. A scalar comparison of the energy market when the virtual power plant is simultaneously participating in the energy-frequency modulated market (Case 1) versus the energy market when it is only participating in the energy market (Case 2) is given by fig. 4.
As can be seen from fig. 3, due to the temporal correlation between the photovoltaic output and the air conditioning load, the bidding period of the virtual power plant participating in the frequency modulation auxiliary service market is mainly concentrated in the daytime. Meanwhile, the difference between the upper frequency modulation capacity and the lower frequency modulation capacity provided by the air conditioner load virtual energy storage is not large, and the photovoltaic can selectively provide a frequency modulation capacity in the same time period. In addition, the total capacity of the lower frequency modulation provided by the photovoltaic all day is obviously larger than that of the upper frequency modulation, which is mainly because the opportunity cost generated by light abandoning when the photovoltaic provides the lower frequency modulation is generally lower than the opportunity cost generated by the upper frequency modulation provided by the photovoltaic and cannot obtain the energy market income, and even if the frequency modulation market is out of date, the loss caused by the incapability of participating in the energy market can be considered.
As can be easily seen from fig. 4, when the virtual power plant adopts a bidding strategy of participating in both the energy and frequency modulation markets, the electric quantity higher than the actual demand is purchased from the energy market at a time of a large photovoltaic output in the middle of the day to meet the demand of providing the frequency modulation capacity, which shows that the virtual power plant has a higher enthusiasm for participating in the frequency modulation auxiliary service market under the condition of having the same resource, and thus the economic benefit of the virtual power plant can be further increased. However, if the actual response index of the virtual power plant participating in the frequency modulation market is poor, which leads to the reduction of the capacity medium-to-standard ratio in the frequency modulation market, a completely different result occurs.
The above analysis contrasts the different behaviors of the virtual power plant when participating in the energy market under both conditions. To further illustrate the policy advantage of the intelligent building type virtual power plant participating in the energy and frequency modulation markets simultaneously when the air conditioner load virtual energy storage is considered, the embodiment compares the expected operating costs of the virtual power plant under three conditions, as shown in table 1. Wherein, Case 1 is the proposal provided by the invention, and considers the air-conditioning load virtual energy storage and participates in the energy-frequency modulation market at the same time; the virtual power plant in Case 2 also participates in the energy-frequency modulation market at the same time, but does not consider the virtual energy storage of the air conditioner load; the virtual power plant in Case 3 only participates in the energy market and does not consider virtual energy storage.
TABLE 1 comparison of virtual plant operating costs under different market strategies
Case 1 2 3
Expected cost/USD 1514.62 2026.74 4085.01
As can be seen from the table, the expected operation cost obtained by adopting the virtual power plant optimization control method provided by the invention is reduced by about 63% compared with the expected operation cost obtained by only participating in the energy market in the virtual power plant, and the fact that the virtual power plant utilizes the adjustability of resources to participate in the frequency modulation auxiliary service market has obvious economic benefit. Meanwhile, the economic advantage that the virtual power plant participates in the frequency modulation market can be further expanded by providing the frequency modulation capacity by utilizing the virtual energy storage characteristic of the air conditioner load.
