Individual purchases of smart home appliances, solar and storage systems, and electric vehicles (EV) are exponentially increasing the number of distributed energy resources (DER), which can generate, store, or flexibly draw energy from the grid.
In this part, we consider the case where households own individual energy storage and do not share these resources, i.e, own PESs. The first observation is that when households install PV systems and PESs, the flexibility of controlling their demand is much higher and thus the aggregator’s electricity cost can decrease significantly.
The operation scheduling for households is optimized given different allocation options of the energy storage from private energy storage to community energy storage. The proposed framework includes three parts: community setup, allocation options for energy storage, and operational cost optimization.
By using k -means to allocate energy storage and formulating a MILP model to optimize the operational cost, different scenarios, including different types of appliances, PV systems, energy storage, and household power consumption profiles are compared in an individual setup as well as a community setup.
With its bi-directional and flexible power characteristics, energy storage can effectively solve the security and stability issues brought by the integration of distributed power generation into the distribution network, many researches have been conducted on the urban distribution networks.
However, the fairness of utilizing the community energy storage system should be considered in the allocation phase, in other words, it might cause problems if the ratio of charging and discharging is not satisfactory in a given community, causing some households to always provide power to other households.
