Cumulative energy storage loss curve

How to reduce energy loss in a distribution system?

Significant loss minimization is obtained by optimal location of multiple energy storage units through peak shaving. Energy storage (ES) is as an essential component in distribution system when large amount of renewable resources are involved with their inherent intermittency.

What is the optimal location of energy storage for loss minimization?

Optimal location of energy storage for loss minimization is achieved by GWO algorithm. The search agents are initialized as 20, and the termination criteria is fixed to 150 iterations or a tolerance value of 10 −6, whichever is met first.

How to evaluate battery life loss?

Besides the statistics for cycle times, another way to evaluate the battery life loss is the throughput energy method . Based on the LCT–DOD relation curve, the BESS total throughput energy in discharge–charge cycles with different DODs can be derived from product of LCT and DOD in the relation curve .

How to calculate Bess life cycle loss?

With the BESS LCT–DOD relation curve, the life cycle loss of the BESS during the study time horizon can be evaluated by accumulating the life cycle loss of each equivalent discharge–charge cycle determined by the rain-flow algorithm . The rain-flow algorithm is a mature method to calculate the BESS life cycle loss.

Does peak shaving reduce energy loss in a 34-bus test system?

The results are compared with the well-known genetic algorithm. The proposed methodology is illustrated by various case studies on a 34-bus test system. Significant loss minimization is obtained by optimal location of multiple energy storage units through peak shaving.

What are residual load duration curves (RLDC)?

Based on empirical data from the UK National Grid, the statistical properties of renewable energy sources and of the energy and power capacities of energy storage technologies, different basic functional relationships between the residual Load Duration Curves (rLDC) will be derived for these technologies.
