Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0076] Application Overview
[0077] In the power market environment, the uncertainty of demand behavior of power suppliers and demanders affects the decision-making of both parties. Agent-based system technology has good sustainability / efficiency in simulating and modeling unit scheduling optimization in the market environment. It enables participants to adjust their unit output behavior in the market environment. In the market environment, since power generators and demanders do not know each other's information, it is difficult to balance power. This is the most realistic situation in the power market. In response to this gap, the optimization decision of power unit output is made by using two-level optimization problems in a market environment with elastic demand. Based on this, the present invention proposes a two-layer power unit output scheduling optimization method based on optimal order equilibrium. The optimal order equilibrium and Lagrangian relaxation method are used to optimize the unit output.
[0078] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail with reference to the accompanying drawings.
[0079] Exemplary Methods
[0080] Figure 1FIG. 1 is a flow chart of a method for optimizing the output dispatch of a double-layer power unit based on priority order balancing provided by an embodiment of the present application. Figure 1 As shown, the method includes the following contents.
[0081] Step S110, constructing a strategic output model of the power generator based on the power generation data and power generation strategy of the power generator;
[0082] First, it is necessary to collect the power generation data of the power generator, including the output of each power generation unit, power generation cost data, etc. These data are the basis for model construction and can reflect the operating status and performance of the power generation unit. Understand the power generation strategy of the power generator, including its positioning, goals, and competitive strategies in the market. For example, the power generator may adopt a low-price strategy to gain more market share, or a high-price strategy to obtain higher profits.
[0083] Based on the collected power generation data, the energy production cost of the power generation unit is analyzed, including fixed costs (such as equipment depreciation, insurance and management fees) and variable costs (such as fuel costs, employee wages, maintenance costs, etc.). Clarifying the cost structure helps power generators make reasonable decisions when quoting.
[0084] Considering factors such as power generation data, power generation strategy and cost structure, a strategic output model of power generators is constructed. The model needs to be able to describe the output behavior of power generators under different circumstances, and how power generators adjust their output according to market conditions to maximize profits. The model may include the relationship between power generator output and cost and revenue, as well as the bidding strategy of power generators.
[0085] Step S120, constructing a power demand model of the seller based on the seller's power consumption data and power consumption strategy;
[0086] Specifically, collect the seller's electricity consumption data, including electricity consumption, electricity consumption time distribution, and types of electricity-consuming equipment. These data can reflect the characteristics and patterns of the seller's electricity demand. Understand the seller's electricity strategy, such as whether it has taken energy-saving measures, whether there are electricity adjustments under the peak and valley electricity price strategy, etc. These strategies will affect the seller's electricity demand pattern.
[0087] According to the electricity consumption data and electricity consumption strategy, establish the electricity demand function. The demand function describes the relationship between electricity demand and factors such as market price and electricity consumption time. For example, the demand function may be a linear or nonlinear function of price, reflecting the impact of price changes on demand. Construct a seller's electricity demand model, which includes demand functions, consumer bidding strategies, etc. The model needs to be able to predict the seller's electricity demand and bidding behavior under different market conditions, and provide accurate demand information for subsequent unit scheduling optimization.
[0088] Step S130, constructing a two-layer model for unit scheduling optimization based on the strategic output model of the power generator and the power demand model, so as to determine the output plan of the power generator through the two-layer model for unit scheduling optimization.
[0089] Specifically, the strategic output model of power generators and the power demand model are integrated to form a basic framework for unit dispatch optimization. In this framework, the output decisions of power generators and the demand decisions of sellers influence each other and jointly determine the supply and demand balance of the power market.
[0090] The structure of the two-layer model is constructed. The upper model focuses on maximizing the profits of power generators and sellers, while the lower model focuses on the equilibrium of market supply and demand. In the upper model, power generators and sellers optimize their output and demand decisions based on their own strategies and market information; the lower model uses optimization algorithms such as Lagrangian relaxation method to solve the optimal solution of market supply and demand balance.
[0091] The optimization algorithm such as Lagrange relaxation method is used to solve the priority equilibrium problem in the two-layer model. The algorithm transforms the constraint conditions into part of the objective function by introducing Lagrange multipliers, thus transforming the complex constraint optimization problem into a more solvable form. The final Lagrange multiplier represents the unified transaction price and the optimal dispatch output of each generator unit.
[0092] According to the solution of the two-layer model, the output plan of the power generator is determined. The output plan includes the output arrangement of each generator set in different time periods, as well as the corresponding quotation strategy. This plan enables the power generator to maximize its own profits while meeting market demand and maintain the stable operation of the power market.
[0093] Specifically, the strategic output model of the power generator is established. The goal of the power generator is to optimize the output of the unit and maximize the profit while considering the energy production cost.
[0094] Energy production cost C per generator set k as follows:
[0095]
[0096] O k =F ck +S ck +M k-1 +M k-2 (2)
[0097] Among them, q k is the output of the generator set; a k and b k is the cost coefficient parameter of unit k of the power generation enterprise; kis the total marginal operating cost of k generators, where F ck As fixed costs consisting of insurance and administrative expenses; S ck 、M k-1 and M k-2 It is a variable cost consisting of labor, processing materials and maintenance costs.
[0098] The power generators offer the following:
[0099] V k =β k +α k q k (3)
[0100] Among them, V k is the energy bid price taking into account all operating costs, q k is the generator output, α k and β k is the strategic quote coefficient.
[0101] Each power generation company calculates revenue and profit using the following formula.
[0102]
[0103] Among them, k is the profit of the power generation unit k of the power generation enterprise, It is the market price.
[0104] Furthermore, the electricity demand model of the seller is established.
[0105] Electricity sales companies are medium-sized and large consumers, and their demand is variable and elastic. The consumer's load demand function is a linear inverse function, and its real marginal benefit curve has a negative gradient. Therefore, the consumer's benefit function is
[0106]
[0107] Among them, B j is the demand function; q j is the quantity demanded; c j and d j is the real benefit coefficient; z j are the coefficients of the demand function.
[0108] The consumer's offer is
[0109] W j =γ j -δ j q j (6)
[0110] Among them, W jis the strategic price variable that each consumer J submits to the market. j and δ j It is the seller's strategic quotation coefficient.
[0111] The revenue of each consumer enterprise is a function of electricity demand and transaction price, as shown below
[0112]
[0113] Furthermore, a two-layer model for unit scheduling optimization is established.
[0114] The present invention adopts a trading order equilibrium model to determine energy supply and demand, thereby optimizing the output of the unit.
[0115] MinH
[0116]
[0117] Among them, J and K represent the number of electricity demanders and electricity supply units.
[0118] The present invention adopts Lagrangian relaxation method to solve the problem of optimal order equilibrium. The solution of Lagrangian multiplier becomes a unified transaction price, and then the optimal dispatch output of each generator set can be obtained.
[0119]
[0120] Where L is the Lagrangian function and λ is the Lagrangian multiplier.
[0121] Use the following as the Lagrange multiplier solution:
[0122]
[0123] Both the generators and the power demanders become decision makers for the dispatch output of the units. This dual behavior forms a two-level mathematical problem, in which the upper level is represented by the benefits obtained by the generators and the demanders in equations (4) and (7), and the lower level is represented by the market supply and demand priority equilibrium model. Therefore, the decision of each market participant is formulated in a two-level mathematical optimization problem of the two functions given in equations (14) and (15).
[0124] Upper model
[0125]
[0126] Lower model:
[0127] MinH
[0128]
[0129] The solutions of the upper and lower models ultimately provide the optimized results of unit dispatch output.
[0130] Due to the adoption of the above technical solution, the present invention has the following advantages: the present invention models producers and consumers as agents with incomplete information of competitors. The agent determines the optimal dispatch output of the unit to achieve the maximum profit under the balance of power supply and demand and Nash equilibrium. The method proposed in the present invention can guide the power generator to form an optimal power supply plan without knowing the information of the demand side. Therefore, the present invention can be widely used in the output dispatch of power units.
