Wind power plant and power-to-gas plant and station collaborative location planning method

Abstract

The invention discloses a wind power plant and power-to-gas plant and station collaborative location planning method. The method comprises the following steps: 1) establishing a mathematic model of a power-to-gas plant and station; 2) with historical wind speed time series being an original scene, carrying out clustering analysis on a large number of historical data by utilizing a density-based clustering algorithm to obtain a reduced wind power plant output scene; 3) according to the mathematic model obtained in the step 1) and the wind power plant output scene obtained in the step 2), and with net investment income maximization being an optimization objective, establishing a collaborative location planning mathematical model based on scene analysis; and 4) according to the steps 1)-3), solving the constructed collaborative location planning mathematical model of the wind power plant and the power-to-gas plant through an AMPL / BONMIN solver to obtain a planning result. The collaborative location planning method can take technical features of operation of the power-to-gas plant and station into consideration, can evaluate and analyze economy of the planning scheme and can effectively reduce system wind abandoning quantity.

Description

technical field [0001] The invention relates to the field of electric power system planning, in particular to a collaborative site selection planning method for wind farms and power-to-gas plants. Background technique [0002] In recent years, the environmental pressure brought by energy consumption has gradually increased, and the focus of energy development and utilization has gradually shifted to wind energy and other renewable energy sources. However, in the transformation and utilization of renewable energy, the phenomena of abandoning wind and solar still exist. In order to improve energy conversion and utilization efficiency, the coupling between different energy systems has gradually attracted attention. The traditional power system is connected with the natural gas system through the gas-fired unit, but the power-to-gas (PtG) technology that has emerged in recent years makes the closed-loop coupling between the two possible. PtG technology can convert electrical e...
