Energy storage subsystems need to be identified that can integrate with distributed PV to enable intentional islanding or other ancillary services. Intentional islanding is used for backup power in the event of a grid power outage, and may be applied to customer-sited UPS applications or to larger microgrid applications.
In addition, according to the partitioning results, a bilevel co-ordination planning model for distributed photovoltaic storage was developed. The upper level aimed to minimize the annual comprehensive cost for which the decision variables are the photovoltaic capacity, energy storage capacity, and power of each partition.
Identify inverter-tied storage systems that will integrate with distributed PV generation to allow intentional islanding (microgrids) and system optimization functions (ancillary services) to increase the economic competitiveness of distributed generation. 3.
The payback period was reduced by 33.3%. By taking advantage of energy sharing, the proposed design can improve the cost-effectiveness of distributed battery system in solar powered building community.
At present, due to the fact that large-scale distributed photovoltaics can access distribution networks and that there is a mismatch between load demand and photovoltaic output time, it is difficult for traditional distributed photovoltaic planning to meet the partition-based control of high permeability photovoltaic grid-connected operations.
This study has proposed a hierarchical design optimization of distributed batteries in solar power shared building community. The developed design method first considers all the distributed batteries as a virtual ‘shared’ battery and searches the optimal capacity of the virtual ‘shared’ battery using genetic algorithm.
