The scenario
A 5 MW utility-scale solar PV plant coupled with a 2.5 MWh battery energy storage system (BESS) exports power to a 115 kV grid through a medium-voltage collection bus and main step-up transformer.
What is in this drawing
Read the decisions behind it.
01
PV array and BESS are connected through dedicated feeders to a common MV bus, allowing independent control and protection.
02
BESS is represented as a load with power conversion system (PCS) because the schematex-sld catalog lacks a dedicated battery/inverter symbol.
03
Revenue metering is placed on the HV side for grid interconnection billing.
Use this template for preliminary design or interconnection studies of utility-scale solar-plus-storage projects where the BESS is modelled as a controllable load/generator at the MV level.
