Research on Gansu Power Transmission Capacity under Multi-energy Complementary

With the construction of a large number of new energy sources such as wind power and photovoltaic in Gansu, the rate of abandoning wind and light is increasing, and the problem of new energy consumption is becoming increasingly prominent. Considering the characteristics of various power stations in the multi-energy complementary power system, it is very important to formulate the working position and working capacity of each power station on the load curve and reduce the amount of new energy curtailment as much as possible. Different from the traditional production simulation method, the power production simulation program used in this paper can better adapt to the access of new energy sources such as large-scale wind power and photovoltaic. In this paper, different consumption guarantee measures are formulated for different new energy volumes. By analyzing the evaluation indicators such as power generation reliability, abandoned power, operation economy and tie-line transaction, the scale of Gansu power transmission that can guide the operation mode is proposed.
