“…The results of the EMS showed the economic benefit of the proposed unit commitment with a rolling horizon (UC-RH) in comparison with a standard unit commitment (UC). In [47], Wang et al developed an MG control system using batteries to support a critical facility. In [11], Alfieri et al performed research of the influence of the control of the reactive power exposing two different control strategies (Active Power Control and Active and Reactive Power Control) and demonstrating, through a simulation carried out in MATLAB/Simulink, the importance of the reactive power control at the point of common coupling (PCC) in an AC/DC hybrid MG.…”

Electric microgrids based mainly on renewable energies have seen a big expansion in recent years due to the great advantages they present against fossil fuels. Nowadays different governments are becoming aware of the use of environmentally friendly energies, so progressive investment has been granted to the consumers in Spain. Many microgrids have been installed in both connected and isolated circumstances, and this fact brings new challenges regarding the technical and economic points of view. This study aims to delve into electrical microgrids based on renewable energies applied in industrial facilities through a review of the literature associated with the study of general microgrids. It later focuses on the relationships between renewable energies and industrial environments. A brief reference is made to the use of energy storage systems in industrial installations depicting the most used systems. This paper presents a review of the state of the art of microgrids from distributed energy resources technologies to industrial microgrids optimization, with the primary objective of providing insight on current trends and directions in research and further identifying areas in need of further development.

“…Dalam Rancangan Umum Energi Nasional (RUEN), pemerintah Indonesia memiliki target bauran Energi Baru Terbarukan (EBT) sebesar 31% pada tahun 2050 [1]. Terdapat beberapa upaya dari peneliti maupun pemerintah untuk meningkatkan penggunaan EBT, salah satunya penerapan microgrid cerdas [2]. Microgrid cerdas didefinisikan sebagai sistem pembangkit lokal dan beban listrik yang saling terinterkoneksi [3].…”

Penelitian ini mengevaluasi kinerja microgrid cerdas dengan tujuan untuk meningkatkan ketersediaan pasokan listrik dan renewable fraction (RF). Evaluasi dilakukan dengan simulasi multi skenario yang mencakup produksi dan konsumsi energi. Simulasi dibagi tiga, yaitu skenario dasar, skenario uji, dan skenario rekomendasi. Skenario uji terdiri dari uji kapasitas sistem, penggantian komponen, dan analisis sensitivitas. Didapatkan dari skenario dasar bahwa ketersediaan pasokan listrik selama setahun telah terpenuhi, dengan RF 30,5%; cost of energy (CoE) Rp2.019/kWh; dan waktu otonomi baterai (WOB) 11,1 jam. Dari hasil analisis didapatkan beberapa rekomendasi berupa penggantian komponen baterai dan modul surya, penambahan kapasitas baterai, dan pengaturan batas state of charge (SoC) pada baterai untuk meningkatkan RF. Skenario rekomendasi tersebut berhasil meningkatkan ketersediaan pasokan listrik dan mencapai target dengan nilai WOB sebesar 37 jam dan RF sebesar 46,4% pada awal siklus hidup proyek; serta WOB sebesar 25,5 jam dan RF sebesar 29,1% pada akhir tahun ke 25, dengan CoE sebesar Rp6.448/kWh. Analisis sensitivitas operasi baterai lead-acid menunjukkan bahwa untuk mendapatkan RF maksimal rentang pengaturan SoC berada pada 0-20%. Sedangkan untuk baterai Li-Ion, rentang SoC adalah 0-25%.

“…In this context, one of the selected consumers was the AES Brasil Generation Operation Center (COGE), which is considered a critical infrastructure due to the nature of its operations, concentrating the operation of all power plant generation managed by AES Brasil. The COGE operates 24-h a day and 7 days per week and has redundant power sources to maintain the continuous power supply to the critical loads, even in main grid contingency scenarios or the unavailability of a backup power source [12,14,15].…”

Cost and Cybersecurity Challenges in the Commissioning of Microgrids in Critical Infrastructure: COGE Case Study

et al. 2022

View full text Add to dashboard Cite

The application of microgrids in critical infrastructures has grown considerably due to the power supply reliability and resilience, and the island operation possibility of providing independence from the main grid. However, the necessity of intense information exchange between the devices that compose the microgrid to their proper operation, and the communication infrastructure required to realize that, makes the system vulnerable to cybersecurity threats. In this context, the case study presented in this paper raises two important subjects of discussion in the Brazilian electrical sector context, which are microgrids and cybersecurity in critical infrastructures of the electrical sector. Therefore, this paper presents the practical challenges related to these two subjects by reporting the development, implementation, and commissioning of a new microgrid controller, and the solutions found to accelerate the development by reducing costs, mitigating risks, and optimizing the commissioning time.
