Abstract
Pembangkit Listrik Tenaga Bayu (PLTB) merupakan salah satu pembangkit listrik baru terbarukan yang memanfaatkan energi angin sebagai bahan bakar. Energi angin dapat diperoleh secara gratis (tidak memerlukan biaya bahan bakar) dari alam. Sehingga daya yang dibangkitkan oleh PLTB harus diinjeksikan secara maksimal. Namun, angin memiliki sifat yang relatif berubah-ubah. Pada PLTB, kondisi angin relatif besar pada saat beban tidak puncak (off peak load) dan relatif kecil pada saat beban puncak (on peak load). Untuk mengatasi hal ini, dapat digunakan Energy Storage System (ESS). ESS dipasang dan diintegrasikan dengan sistem untuk menyimpan daya yang tak terpakai pada saat beban tidak puncak (charging) dan akan disalurkan kembali (discharging) ke saluran sistem saat beban puncak. Akan tetapi, daya yang disalurkan melalui kedua proses tersebut masih belum tentu optimal seiring dengan perubahan beban setiap saat. Oleh karena itu, diperlukan analisis aliran daya optimal dinamis atau Dynamic Optimal Power Flow (DOPF) dengan menggunakan metode Sequential Quadratic Programming (SQP). Dari hasil simulasi pada sistem IEEE 14 bus modifikasi menunjukkan bahwa SQP dapat digunakan untuk menyelesaikan DOPF tanpa melanggar parameter ramp rate yang sudah ditentukan. Selain itu, energi yang disimpan pada ESS memiliki nilai yang sama besar dengan energi yang dikeluarkan dari ESS. Sehingga total biaya pembangkitan dengan menggunakan ESS lebih murah dibandingkan tanpa menggunakan ESS.

Wind power generation is one of renewable energy generation that using wind as a fuel . Wind energy can be obtained for free (does not requaire fuel cost) of nature. So that the power of wind energy should be injected to the maximum. But, the wind has characteristics that changes. At wind power, wind conditions are relatively high when off peak load and low when on peak load.. To solve it, needed Energy Storage System (ESS). ESS was installed and integrated with the system to save unused power for a few minutes (charging) and will be distributed back (discharging) to system when peak load. However, the power is distributed through these two processes is not necessarily optimal along with increased load or demand changes every times. Therefore, the dynamic optimal power flow (DOPF) anlaysis is required using by sequential quadratic programming (SQP) methods. From the results of the simulation have been performed on the IEEE 14 bus modified system shows that the SQP can be used to resolve DOPF without violating parameter ramp rate which is already specified. In addition, the energy charged in the ESS has a value equal to the energy in the discharge of the ESS. So, the total cost of generation using ESS is cheaper than without using ESS.
