Saat ini, dengan meningkatnya kebutuhan energi global dan peningkatan kesadaran akan dampak negatif penggunaan bahan bakar fosil terhadap lingkungan, kebutuhan akan penyimpanan energi yang efisien dan ramah lingkungan semakin penting. Energy storage atau penyimpanan energi menjadi solusi yang banyak diteliti dan dikembangkan dalam upaya mengatasi masalah pasokan energi yang bervariabilitas. Optimasi operasi Pump Storage Hydroelectricity (PSH) menjadi penting untuk memaksimalkan efisiensi dari sistem ini. Terdapat beberapa faktor yang perlu dipertimbangkan dalam melakukan optimasi, seperti pengaturan beban sistem, manajemen waktu pengisian dan pengosongan waduk, serta efisiensi konversi energi. Dengan menggunakan model matematika dan algoritma yang tepat, proses pengaturan operasi dapat dioptimalkan sehingga penggunaan energi dapat ditingkatkan, biaya operasional dapat ditekan, dan respon sistem terhadap perubahan permintaan energi dapat dipercepat. Hasil penelitian menunjukkan bahwa optimalisasi sistem pembangkitan dengan integrasi Pumped Storage Hydroelectricity (PSH) mampu meminimalkan biaya pembangkitan. Pada sistem IEEE 10, total daya yang dihasilkan sebesar 13.655,47 MW dengan biaya pembangkitan sebesar US$ 428.382.050,14. Penggunaan PSH menghasilkan penghematan biaya sebesar US$ 6.351.348,75 (sekitar Rp104,51 miliar) dibandingkan sistem tanpa PSH. Dynamic Economic Dispatch (DED) sendiri merupakan metode pembagian beban ekonomis yang memperhitungkan perubahan beban secara real-time, menjadikannya peningkatan dari metode Economic Dispatch (ED) konvensional.

Nowadays, with the increasing global energy demand and awareness of the negative impact of fossil fuel use on the environment, the need for efficient and environmentally friendly energy storage is increasingly important. Energy storage is a solution that is widely researched and developed to overcome the problem of variable energy supply Pumped storage hydroelectricity (PSH) operation optimization is important to maximize the efficiency of this system. There were several factors to consider in optimization, such as system load management, reservoir filling and emptying time management, and energy conversion efficiency By using mathematical models and appropriate algorithms, the operation setting process can be optimized so that energy use can be improved, operational costs can be reduced, and system response to changes in energy demand can be accelerated The results indicate that the optimization of the generation system with the integration of pumped storage hydroelectricity (PSH) was able to minimize the cost of generation. In the IEEE 10 system, the total power generated was 13,655.47 MW with a generation cost of US$428,382,050.14. The use of PSH resulted in cost savings of US$6,351,348.75 compared to the system without PSH. Dynamic Economic Dispatch (DED) itself is an economic load-sharing method that takes into account real-time load changes, making it an improvement over the conventional Economic Dispatch (ED) method.
