Are HES and CES a viable storage scenario for residential electricity prosumers?

Household Energy Storage (HES) and Community Energy Storage (CES) are two promising storage scenarios for residential electricity prosumers. This paper aims to assess and compare the technical and economic feasibility of both HES and CES.

What are energy storage systems & demand side management (DSM)?

Energy Storage Systems (ESS) combined with Demand Side Management (DSM) can improve the self-consumption of Photovoltaic (PV) generated electricity and decrease grid imbalance between supply and demand. Household Energy Storage (HES) and Community Energy Storage (CES) are two promising storage scenarios for residential electricity prosumers.

What is Community Energy Storage (CES)?

Community Energy storage (CES) is another application of ESS which is seen as a promising option for managing power demand and DERs supply. In , CES is referred to as ’ESS located at the consumption level with the ability to perform multiple applications with a positive impact for both the consumer as the Distribution System Operator (DSO)’.

What is a household energy storage (HES)?

Surplus energy can be stored temporarily in a Household Energy Storage (HES) to be used later as a supply source for residential demand . The battery can also be used to react on price signals . When the price of electricity is low, the battery can be charged.

Are CES and HES storage economically feasible for end-consumers?

The results in Section 5 shows that both CES and HES storage are not economically feasible for end-consumers. The sensitivity analysis results show that, in the current model setup, both HES and CES systems react similarly to changing battery sizes and investment costs.

How is HES storage capacity calculated?

The HES storage capacity is identical for each household, therefore the average capacity equals the HES storage capacity in scenario I. In scenario II it represents the average battery share per household. For calculating the shares in scenario II, we assume that households are able to store their grid injection 90% of the time.
