Self-consumption of PV electricity with active demand side management: The GEDELOS-PV system

Abstract

Because of the recent technological developments within the field of power conditioning and the progressive decrease of incentives for PV electricity in grid-connected markets, new operation modes for PV systems should be explored beyond the traditional maximization of PV electricity feed-in. We have developed the GeDELOS-PV system as an example of added value for PV electricity which arises from the combination of modern hybrid PV technology with a lead-acid battery storage system and Demand Side Management strategies in the residential sector. We carry out simulations for long-time experiments (yearly studies) and real measurements for short and mid-time experiments (daily and weekly studies). Results show that the relationship between electricity flows and storage capacity is not linear and therefore, it becomes an important design criterion.
