Integrated Transmission Scheduling Model for Wind-Photovoltaic-Thermal Power by Ultra-high Voltage Direct Current System
摘要
Abstract
With the increase of large-capacity power bases and the rapid development of ultra-high voltage AC and DC power supply,large-capacity power and long distance transmission will become a normal state of affairs.The demand on trans-regional transmission of wind-photovoltaic clean energy by ultra-high voltage direct current (UHVDC) system is steadily growing.To solve the transmission problem due to the random fluctuation of wind-photovoltaic power,a bundled wind-photovoltaic-thermal power transmission plan is used.In view of the actual situation of the DC generation plan being relatively independent of the wind-photovoltaic power generation and the supporting thermal power inefficient in its part in wind-photovoltaic power adjustment,an integrated transmission scheduling model for bundled wind-photovoltaic-thermal power transmission by UHVDC system is proposed.The model can deal with the coordination problem between the wind-photovoltaic power,supporting thermal power,electric power trading and DC plan.The proposed model has been applied to a case in point. Simulation results show that the participation in adjustment of supporting thermal power and DC plans can effectively enhance the transmission capacity of wind-photovoltaic power.关键词
