摘要

随着中国大容量电源基地的逐渐增多及特高压交直流电网的快速发展，大功率远距离输电将成为常态。通过特高压直流跨区输送风光清洁能源的需求日益强烈，为解决风光能源随机波动不易直流外送的问题，设计中采用了配套火电平抑风光电力波动整体打捆外送方案。针对当前直流发电计划与风光发电计划相对独立及配套火电未能有效参与风光电力调整的实际情况，文中提出了特高压直流外送风光火电力一体化调度计划模型。该模型能够灵活处理外送风光电力、配套火电、电力交易及直流计划的协调问题。将所述模型运用于实际算例，仿真结果表明配套火电和直流计划参与调整能有效提升风光电力外送能力。

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.
