Embodiment
[0065] like figure 1 As shown, this embodiment provides a method for optimal configuration of energy-efficient power plants and coordinated planning of power plants based on the uncertainty method, the method includes the following steps:
[0066] S1 According to the two-level programming theory and the constraints of transmission network planning, establish a two-level planning model for the transmission network considering energy efficiency power plants, and consider the upper model of the plant-network coordination planning model for energy efficiency power plants. Line investment cost, power plant (conventional power plant, EPP, wind farm and photovoltaic power plant) investment and operation cost, and load shedding penalty cost; the lower-level planning model takes the minimum investment cost of the power plant as the objective function, including the construction cost of new conventional power plants and the construction of new energy-efficient power plants Cost, new pho...

The invention relates to an energy efficiency power plant optimization configuration and plant net planning method based on a nondeterminacy method; the planning method comprises the following steps: 1, using a nondeterminacy two-layer planning method to build an energy efficiency power plant optimization configuration and plant net expansion coordination planning model including an upper layer planning model and a lower layer planning model; 2, using a mixed algorithm formed by an improved adaptive heredity algorithm and an equivalent electric quantity frequency method to solve the lower layer mathematics model, and verifying the connectivity thereof; 3, using a mixed algorithm formed by the improved adaptive heredity algorithm, a variable precision rough set theory and a primal dual interior point method to solve the upper layer mathematics model, thus obtaining the energy efficiency power plant optimization decision and plant net expansion plan optimization decision coordination planning optimization solution. Compared with the prior art, the energy efficiency power plant optimization configuration and plant net planning method is accurate in calculation and simple in planning.
Description
technical field [0001] The invention relates to the fields of power supply planning and grid planning, in particular to a method for optimal configuration of an energy-efficient power plant and a plant network planning method based on an uncertainty method. Background technique [0002] The continuous development of power system puts forward new requirements for power planning. For a long time, power supply planning and power grid planning have been carried out separately in research and practice. After all, the subjects of power supply construction and power grid construction are diverse. However, in recent years, as issues such as "abandoning wind" and "abandoning light" have become more prominent, the incoordination and mismatch between power supply and power grid planning and construction have begun to attract people's attention and thinking. In order to make more optimal use of resources and meet electricity demand more economically and economically, power supply plann...
