UNIT DECOMMITMENT METHOD FOR THERMAL POWER SYSTEM OPTIMIZATION STUDY ON PLNs PUBLIC COMPANY JAVA BALI ELECTRIC POWER GENERATION
Author : TR1 WRAHATNOLO
ABSTRAK
Tesis ini memperkenalkan sebuah metode unit commitment baru berbasis pada prosedur decommitment untuk menyelesaikan problem penjadwalan sumber sistem daya. Dari penjadwalan awal semua unit yang dipersiapkan menanggung periode studi pada suatu waktu dilakukan decommitment unit yang diselesaikan dengan Dynamic Programming DP menurut beberapa kriteria ekonomic yang spesifik. Proses decommitment berlangsung secara kontinyu sehingga tidak mungkin dilakukan pengurangan biaya total atau penjadwalan unit pada dua iterasi yang berurutan mencakup sisa periode waktu yang tanpa mengubah beberapa pelanggaran batasan spinning reserve. Kriteria untuk decommitting dari sebuah unit dikenalkan dan ditunjukkan secara rihci Perbandingan dari metode unit decommitment yang diajukan dengan pendekatan DP menunjukkan kelebihan secara potensial dari pendekatan yang diajukan untuk perencanaan operasi sistem daya. Pengajuan pendekatan ini akan digunakan untuk penjadwalan unit-unit termal pada PT. PLN Persero Pembangkitan Tenaga Listrik Jawa-Bali.
ABSTRACT
This tesis introduces a unit commitment method based on a decommitment procedure for solving the power system resource scheduling problem. From an initial schedule of all available units committed over the study period a one-at-a-time unit decommittment is accomplished by Dynamic Programming according to some specified economic criteria. The decommittment process continues until no futher reduction in total cost is posible or the unit schedules of two consecutive iterations over the time period remain unchanged without any violation of the spinning reserve constraint. Criteria for decommitting a-unit are introduced and described in detail. Comparisons of the proposed unit commitment method with the Dynamic Programming DP demonstrate the potential benefits of the proposed approach for power system operations planning. This unit decommitment approach to implementation for unit thermal short-term scheduling on PLNs Public Company Java-Bali Electric Power Generation.
