A novel formulation for the battery energy storage (BES) sizing of a microgrid considering the BES service life and capacity degradation is proposed. The BES service life is decomposed to cycle life and float life. The optimal BES depth of discharge considering the cycle life and performance of the BES is determined.
In order to ensure more reliable and economical energy supply, battery storage system is integrated within the microgrid. In this article, operating cost of isolated microgrid is reduced by economic scheduling considering the optimal size of the battery. However, deep discharge shortens the lifetime of battery operation.
Nowadays, microgrids (MGs) have received significant attention. In a cost-effective MG, battery energy storage (BES) plays an important role. One of the most important challenges in the MGs is the optimal sizing of the BES that can lead to the MG better performance, more flexible, effective, and efficient than traditional power systems.
The optimal battery capacity results in longer lifetime in comparison to other battery capacities and the conventional method . Thus, the optimal size and the economic scheduling may prolong the battery lifetime and reduce the microgrid cost. Fig 13. DOD curves of different battery sizes. Table 7.
The above-mentioned power management strategy is implemented to obtain an optimal battery size and daily economic scheduling of microgrid. The capital cost of battery constitutes a major factor in calculating the battery size. The optimal BESS sizing is obtained by minimizing the daily scheduling cost of the microgrid and BESS total cost per day.
... The integration of battery energy storage systems with photovoltaic systems to form renewable microgrids has become more practical and reliable, but designing these systems involves complexity and relies on connection standards and operational requirements for reliable and safe grid-connected operations.
