Abstract

Saat ini kebutuhan tenaga listrik tidak dapat dipisahkan dari kehidupan manusia. Seiring berjalannya waktu, permintaan akan daya listrik semakin meningkat yang diimbangi dengan perbaikan kualitas dan keandalan dari daya listrik. Selain permintaan beban yang terus bertambah, perubahan level beban pada setiap jam menyebabkan perlu adanya metode optimasi pada pembangkitan tenaga listrik. Dynamic Opimal Power Flow (DOPF) merupakan metode penjadwalan keluaran pembangkit dengan mempertimbangkan faktor-faktor seperti batasan fisik, pengoperasian, analisis aliran daya dan sebagainya. Salah satu faktor yang memengaruhi adalah efekvalve-point. EfekValve-point merupakan pembukaan katup uap pada pembangkitan thermal yang membuat kurva biaya pembangkitan menjadi tidak mulus sehingga perhitungan biaya menjadi tidak linear. Tugas akhir ini membahas DOPF dengan mempertimbangkan valve-point effect menggunakan metode Modified Honey Bee Mating Optimisation (MHBMO). Simulasi dilakukan dengan dua bagian. Bagian pertama melihat pengaruh efek valve-pointdalam OPF, sedangkan bagian kedua melihat performa MHBMO dalam menyelesaikan DOPF dengan efek valve-point yang dibandingkan dengan metode PSO.Hasil simulasi bagian pertama menunjukkan total biaya yang dihasilkan akibat efek valve-pointlebih mahal 178.6466 $/h dibandingkan tanpa efek valve-point. Hasil simulasi bagian kedua menunjukkan bahwa dalam menyelesaikan DOPF dengan efek valve-pointmetode MHBMO menghasilkan biaya pembangkitan lebih murah 19.618 $/hdaripada metode PSO. ========================================================================== Lately, the need for electric power can not be separated from human life. As time passes, demand for electric power is increasing, so does the need for improvements in the quality and reliability of electrical power. In addition to the growing demand for loads, changes in load levels on an hourly basis needs an optimization method for power generation. Dynamic Opimal Power Flow (DOPF) is a method of scheduling the power output of the plant by considering factors such as physical constraints, operation, power flow analysis, etc. One of those factors is the valve-point effect. Valve-point effect is the opening of the steam valve at the thermal generation which makes the generating cost curve to be non-seamless so the cost calculation becomes nonlinear. This final project discusses DOPF by considering the valve-point effect using Modified Honey Bee Mating Optimisation (MHBMO) method. The simulation is done with two parts. The first partobserve the effect of the valve-point effect in OPF, while the second part observe the performance of MHBMO in completing the DOPF with the valve-point effect. The first part simulation results show that the total cost with valve-point effect is 178.6466 $/hmore expensive than without valve-point effect. The second part simulation results also show that in solving DOPF with valve-point effect MHBMO method obtain generating cost 19.618 $/hcheaper than the PSO method.
