Contrary to other proposed approaches, the present work aims at defining an energy management strategy that is able to cope with the main issues of MGs equipped with ESS, i.e., ESS degradation and unexpected outages of the main grid, which can be appreciated only considering long time horizons.
Do tracking systems require more maintenance?
The complexity of tracking systems requires more maintenance—not only on the load-bearing moving parts of the array but also for the associated system for actuators and controls. The additional costs of the tracking system are weighed against the performance gains it is expected to provide.
Why is battery energy storage important?
Battery energy storage can resolve technical barriers to grid integration of PV and increase total penetration and market for PV. Storage can add to the value propositions that PV projects can access and improve the value of PV but also can increase overall costs and add complexity to weigh against the benefits.
