The invention discloses a network source collaborative planning modeling method considering new energy output and electricity price factors, which is characterized in that it includes: step 1: constructing an objective function of network source collaborative planning; Constraints; Step 3: Model the uncertainty of new energy output and add corresponding constraints; Step 4: Obtain the data required for planning and calculation; Step 5: Build an electricity price prediction model and predict the electricity price within the planning period , use the predicted electricity price as the input data of the electricity price of the model; Step 6: Establish a network source collaborative planning model. Through reasonable conception and scheme design, the present invention solves the problems caused by the phase separation of traditional network source construction (such as insufficient power supply or grid transmission blockage, transmission bottleneck, etc.), and well copes with the large-scale access of new energy to the grid. The many challenges brought about by the new energy provide a good guarantee for the access and application of new energy.
Description
technical field [0001] The invention relates to the technical field of power system planning, in particular to a network source collaborative planning modeling method considering new energy output and electricity price factors. Background technique [0002] Power system planning is of great significance to ensure the continuous safe, reliable, scientific and sustainable development of the power grid, and scientific and reasonable power grid planning has great social and economic value. In recent years, with the rapid development of the power system, power planning is also facing many new challenges. On the one hand, the large-scale access of new energy has brought many uncertainties to power grid planning; on the other hand, due to the Uncertainty makes the price of electricity more volatile, and it is difficult to accurately calculate the future income of the power system. The above factors make it particularly important to introduce new energy output characteristics and e...
