【摘要】：以"電量"為紐帶,建立了風(fēng)電接入下的時(shí)序漸進(jìn)滾動(dòng)調(diào)度修正模型。該模型在時(shí)間尺度上包含年計(jì)劃、月計(jì)劃、日計(jì)劃以及實(shí)時(shí)調(diào)度計(jì)劃。時(shí)序漸進(jìn)體現(xiàn)在上一級(jí)時(shí)間尺度為下一級(jí)時(shí)間尺度提供計(jì)劃電量或調(diào)度功率,指導(dǎo)下一級(jí)時(shí)間尺度的調(diào)度安排;滾動(dòng)修正則根據(jù)下一級(jí)時(shí)間尺度提供的實(shí)際發(fā)電量對(duì)上一級(jí)進(jìn)行不斷修正。年計(jì)劃和月計(jì)劃滾動(dòng)修正模型側(cè)重于電量的不平衡修正,在各自時(shí)間尺度內(nèi),結(jié)合下一級(jí)時(shí)間尺度提供的實(shí)際已發(fā)電量以及最新的風(fēng)電、負(fù)荷預(yù)測(cè)信息,滾動(dòng)修正剩余時(shí)段的發(fā)電計(jì)劃,保證各機(jī)組電量的有效實(shí)施。日計(jì)劃、日內(nèi)滾動(dòng)優(yōu)化調(diào)度和實(shí)時(shí)調(diào)度模型側(cè)重于風(fēng)電功率的消納,針對(duì)風(fēng)電的隨機(jī)性和波動(dòng)性,建立基于場(chǎng)景法的日前機(jī)組組合模型和日內(nèi)滾動(dòng)優(yōu)化模型,且僅在日內(nèi)滾動(dòng)調(diào)度和實(shí)時(shí)調(diào)度階段考慮合理?xiàng)夛L(fēng)。最后,通過修改的IEEE-RTS24系統(tǒng)進(jìn)行算例仿真,驗(yàn)證了該模型的有效性。
[Abstract]:Based on the "quantity of electricity" as the link, the paper establishes the time series progressive rolling scheduling correction model under the wind power access, which includes the annual plan and the monthly plan in the time scale. Day plan and real-time scheduling plan. Time series gradually reflect in the next level of time scale to provide the planned power or scheduling power to guide the next level of time scale scheduling arrangements; The rolling correction is based on the actual power generation provided by the next time scale. The annual plan and the monthly plan rolling correction model focus on the unbalanced correction of the electricity in their respective time scales. Combined with the actual power generation and the latest wind power and load forecasting information provided by the next time scale, the generation plan of the remaining period of time can be revised by rolling to ensure the effective implementation of the electricity generation plan of each unit. Intra-day rolling optimal scheduling and real-time scheduling model focus on wind power absorption, aiming at the randomness and volatility of wind power, the pre-day unit combination model and intra-day rolling optimization model based on scenario method are established. And the reasonable abandonment is considered only in the rolling scheduling and real-time scheduling stage. Finally, the validity of the model is verified by the simulation of the modified IEEE-RTS24 system.

【正文快照】： 0引言近年來,由于能源和環(huán)境問題的日益突出,以風(fēng)電為代表的可再生能源引起了越來越多的關(guān)注。由于風(fēng)電具有間歇性和隨機(jī)性的特點(diǎn),因此,制定有效的調(diào)度策略對(duì)于保證系統(tǒng)的安全和提高風(fēng)電的消納水平尤其重要。在時(shí)間尺度上,電力系統(tǒng)有功調(diào)度包括基于預(yù)測(cè)信息的超前調(diào)度計(jì)劃和針
