EPSO-based Methodology for Modelling Equivalent PV-Battery Hybrid Power Plants using Generic Converters Models
02 HYB24-83
Presented by: Rui Pinto de Sousa
System operators (SO) require Converted-Interfaced Renewable Energy Systems (CI-RES) power plants investors to provide
demonstrative studies related to different operational performance capabilities and advanced system services provision to the
grid. Typically, these studies rely on Original Equipment Manufacturer (OEM) simulation models for the power converters and
CI-RES power plants control units. Such models might be unavailable to the SO due to confidentiality reasons and might present
challenges in parametrization due to their complexity. Moreover, compatibility issues between simulation packages used by the
SO and those utilized by the independent entity performing the studies creates additional difficulties. Hence, SO demand to
power plant investors the proving of equivalent simulation models and resorting preferably to standardized open-source models.
This work presents a methodology to derive an equivalent model of a CI-RES power plant using Generic Eenewable Energy
Models (GREM) in which the parameters identification is performed exploiting an Evolutionary Particle Swarm Optimization
(EPSO) to capture the plant´s dynamic behaviour at the Point of Interconnection (POI) in face of a set of reference network
disturbances. Considering as Case-Study the integration of a PV-Battery Hybrid power plat into the electrical system of Terceira
Island, the results demonstrate successful derivation of GREM parameters allowing the representation of the dynamic behaviour
of the power plant in face of network disturbance events.
