“…[15]) also considered the so-called greedy and conservative strategies: greedy always depletes the battery completely before drawing from the power grid and has been shown to lead to a very low survivability. In contrast, the conservative strategy also draws from the grid to recharge the battery if it has been discharged too much.…”

Domestic renewable energy systems, including photovoltaic energy generation, as well as local storage, are becoming increasingly popular and economically feasible, but do come with a wide range of options. Hence, it can be difficult to match their specification to specific customer's needs. Next to the usage-specific demand profiles and location-specific production profiles, local energy storage through the use of batteries is becoming increasingly important, since it allows one to balance variations in production and demand, either locally or via the grid. Moreover, local storage can also help to ensure a continuous energy supply in the presence of grid outages, at least for a while. Hybrid Petri net (HPN) models allow one to analyze the effect of different battery management strategies on the continuity of such energy systems in the case of grid outages. The current paper focuses on one of these strategies, the so-called smart strategy, that reserves a certain percentage of the battery capacity to be only used in case of grid outages. Additionally, we introduce a new strategy that makes better use of the reserved backup capacity, by reducing the demand in the presence of a grid outage through a prioritization mechanism. This new strategy, called power-save, only allows the essential (high-priority) demand to draw from the battery during power outages. We show that this new strategy outperforms previously-proposed strategies through a careful analysis of a number of scenarios and for a selection of survivability measures, such as minimum survivability per day, number of survivable hours per day, minimum survivability per year and various survivability quantiles.

“…But large variations may occur on a day to day basis, since sunny days may be followed by days with many clouds. Figure A.3, taken from [110], shows four day profiles, two days in summer and two days in winter. For both seasons a profile of a sunny day with high production and a profile of a cloudy day with low production are shown.…”

“…Usually the electricity demand will typically be high in winter, and lower in summer. Figure A.2a, taken from [110], shows the average demand profile of a day both in summer and winter. However, to reduce the computational complexity for the HPnG model, we use a coarser approximation.…”
