Abstract

Berbagai upaya dilakukan untuk meningkatkan produksi listrik secara ekonomis dengan memperhatikan penggunaan energi terbarukan. Dynamic Optimal Power Flow (DOPF) dapat digunakan untuk mendapatkan operasi yang optimum dan ekonomis pada berbagai tingkat beban. Namun, masih banyak faktor yang mempengaruhi biaya operasional pada sistem. Take-or-pay (TOP) energi dari Pembangkit Listrik Tenaga Panas Bumi (PLTP) menjadi faktor adanya daya tetap minimal pada sistem. TOP bahan bakar gas pada Pembangkit Listrik Tenaga Gas (PLTG) mengharuskan adanya pemakaian gas sejumlah minimal tertentu pada saat operasi. Keberadaan penyimpanan energi dengan berbagai fungsinya terutama sebagai spinning reserve pada sistem dapat menjadi faktor penentuan operasi yang optimum dan ekonomis. Oleh karena itu, diperlukan DC DOPF dengan mempertimbangkan TOP energi dan gas serta penyimpanan energi untuk operasi optimum dan ekonomis. Pada tugas akhir ini, metode penyelesaian menggunakan mixed-integer quadratic programming dengan bantuan software MATLAB dapat menyelesaikan masalah OPF kompleks tersebut. Penambahan TOP energi dan gas menaikkan rata-rata biaya pembangkitan hingga 1.31%, namun di sisi lain menghindari adanya penalti. Sedangkan penambahan penyimpanan energi, rata-rata biaya pembangkitan pada sistem dengan kontrak TOP dapat diturunkan hingga 1.12% setelah kontrak.

Various efforts have been made to increase electricity production economically by taking into account the use of renewable energy. Dynamic Optimal Power Flow (DOPF) can be used to obtain optimum and economical operation at various load levels. However, there are still many factors that affect the operational costs of the system. Take-or-pay (TOP) energy from Geothermal Power Plants (PLTP) is a factor in the presence of minimal fixed power in the system. TOP gas fuel in Gas Power Plants (PLTG) requires the use of a certain minimum amount of gas during operation. The existence of energy storage with various functions, especially as a spinning reserve in the system can be a factor in determining the optimum and economical operation. Therefore, DC DOPF is needed by considering the TOP of energy and gas as well as energy storage for optimum and economical operation. In this final project, mixed-integer quadratic programming with the help of MATLAB software can be used as solution method. The addition of TOP energy and gas raises the average cost of generation by 1.31%, but on the other hand avoids penalties. With the addition of energy storage, the average generation cost of a system with a TOP contract can be reduced by up to 1.12% after the contract.
