Problems solved by technology

[0002] With the increasingly serious problems of energy depletion and environmental pollution, distributed generators (DG) are gradually being widely used due to their economical, environmental protection, flexibility, and safety characteristics. However, DG has many problems: first, DG has small capacity, The large number and uneven distribution make the single-machine connection cost high; secondly, the connection of DG has brought many technical difficulties to the stable operation of the power grid; thirdly, the current operation mode of DG and the limitation of the power market capacity have further hindered the development of DG Large-scale grid connection
To sum up, the existing research mainly focuses on the interior of the virtual power plant, and improves the economic benefits of the virtual power plant through coordination mechanisms or dispatching methods. The impact of external factors such as weather on the virtual power plant is less considered, and the impact of policy mechanisms on virtual power plants is not considered. The impact of virtual power plants

Embodiment 1

[0057] refer to Figure 1~5 , which is an embodiment of the present invention, provides a distributed power incentive mechanism analysis method for virtual power plants, including:

[0058] S1: Based on the system dynamics theory, draw the causal loop diagram of the virtual power plant day-ahead market, and establish a virtual power plant system dynamics day-ahead market transaction model that aggregates distributed power;

[0059] It should be noted that the virtual power plant system dynamics day-ahead market transaction model for aggregated distributed power includes a virtual power plant distributed power module, a virtual power plant day-ahead market module, and a virtual power plant profit-risk module.

[0060] S2: According to the day-ahead market trading model of virtual power plant system dynamics that aggregate distributed power, analyze the impact of weather and real-time electricity prices on virtual power plant days;

[0061] It should be noted that the distribut...

Embodiment 2

[0101] refer to Figure 6-9 It is another embodiment of the present invention. In order to verify and explain the technical effect adopted in this method, this embodiment is based on the analysis of the solution of the model and the simulation experiment, and verifies the real effect of the method by means of scientific demonstration.

[0102] Traditional technical solutions pay more attention to the representation of results when performing simulations, and it is often difficult to reflect the trend relationship between various units within the simulation. For example, a system input needs to input a parameter and obtain a result. We input each parameter x, y, z, and the simulation results are A, B, C. We can directly or indirectly analyze the influence of the parameters on the final result, and this system Internally, assuming complex calculation relationships involving multiple modules, traditional technical solutions often encapsulate and hide them. When we need the influe...

Abstract

The invention discloses a distributed power supply excitation mechanism analysis method for a virtual power plant, and the method comprises the steps: drawing a virtual power plant day-ahead market causality loop diagram based on a system dynamics theory, and building a virtual power plant system dynamics day-ahead market transaction model for aggregating distributed power supplies; analyzing the influence of weather and real-time electricity price on the virtual power plant day according to the virtual power plant system dynamics day-ahead market transaction model of the aggregated distributed power supply; drawing a virtual power plant long-term market causality loop diagram based on a green certificate transaction mechanism and a carbon transaction mechanism, establishing a long-term transaction model of the virtual power plant participating in the market, analyzing the influence of the green certificate transaction mechanism and the carbon transaction mechanism on the virtual power plant, and completing the analysis of a distributed power supply excitation mechanism. According to the method, the influence of external factors such as weather and policy mechanisms on the virtual power plant can be effectively analyzed, and construction suggestions are provided for the virtual power plant to better participate in marketization transaction.

Description

technical field [0001] The invention relates to the technical field of an incentive mechanism analysis method, in particular to a virtual power plant-oriented distributed power source incentive mechanism analysis method. Background technique [0002] With the increasingly serious problems of energy depletion and environmental pollution, distributed generators (DG) are gradually being widely used due to their economical, environmental protection, flexibility, and safety characteristics. However, DG has many problems: first, DG has small capacity, The large number and uneven distribution make the single-machine connection cost high; secondly, the connection of DG has brought many technical difficulties to the stable operation of the power grid; thirdly, the current operation mode of DG and the limitation of the power market capacity have further hindered the development of DG Large-scale grid connection. The emergence of virtual power plants effectively solves these problems....
