Abstract
As global photovoltaic (PV) penetration accelerates, rapid and accurate simulation across multiple system configurations and operational rules—such as battery dispatch and curtailment—is critical. Current modeling frameworks are often limited by rigid code architectures that require extensive reconfiguration to modify system topologies. To overcome this, we present a matrix-based approach for determining PV state-of-system variables and energy flows. By representing system component states in source-sink matrices and hierarchical selection rules, this method enables exceptional flexibility in adding generation sources or redefining dispatch logic without code modification. This framework allows high-speed, optimized algorithms essential for iterative multi-parameter system optimization and the evaluation of complex grid-interaction constraints.
