Abstract

The invention provides a wind-solar storage capacity planning method based on a carbon transaction mechanism. In a regional power system containing wind-solar storage, the wind-solar storage capacityplanning method establishes a random output model of a photovoltaic power generation system and a wind power generation system according to change characteristics of solar radiation and wind speed onthe basis of mathematical statistics and probabilistic methods; and then considering the carbon transaction cost, taking the minimum total cost of the system as an economic optimization target, solving the optimal solution meeting the constraint condition according to the planning model, and outputting the optimal solution meeting the constraint condition, thereby realizing the optimal configuration of the wind-solar storage capacity of the regional power grid.

Description

technical field [0001] The invention belongs to the technical field of power system power supply planning, and discloses a planning method for wind and solar storage capacity based on a carbon trading mechanism. Background technique [0002] At present, new energy sources such as wind power and photovoltaics are more and more widely used in power systems, and their importance is also increasing. Different from traditional power sources, new energy power generation such as wind power and photovoltaics is often greatly affected by environmental factors, and has significant randomness, volatility and intermittency. Compared with distributed new energy power sources, centralized new energy power sources have stable output and reduce The peak effect is obvious, it is more convenient to carry out reactive power and voltage control, and it is easy to realize the frequency adjustment of the power grid. System for unified planning. [0003] When wind power and photovoltaics are int...
