Краткое
Freelancer Client is hiring: Smart Energy Management System for Solar-Based EV Charging Station Dispatch.
Location: Remote
The convergence of distributed rooftop photovoltaic generation and grid-connected electric vehicle fleets creates a
multidimensional energy-exchange challenge that single-port, AC-coupled charger architectures are structurally ill-equipped
to resolve. Cascaded conversion stages degrade round-trip efficiency while heuristic energy management systems overlook the
measurable financial toll of battery cycling when scheduling vehicle-to-grid discharge. This paper presents a Unified Multiport
Bidirectional Power Routing Architecture that consolidates the PV array interface, a galvanically isolated EV traction battery
Skills: Engineering, Electronics, Electrical Engineering, Circuit Design, Solar, Simulation, MATLAB/Simulink
Budget: $600–$1500 USD

The convergence of distributed rooftop photovoltaic generation and grid-connected electric vehicle fleets creates a
multidimensional energy-exchange challenge that single-port, AC-coupled charger architectures are structurally ill-equipped
to resolve. Cascaded conversion stages degrade round-trip efficiency while heuristic energy management systems overlook the
measurable financial toll of battery cycling when scheduling vehicle-to-grid discharge. This paper presents a Unified Multiport
Bidirectional Power Routing Architecture that consolidates the PV array interface, a galvanically isolated EV traction battery
port, and a three-phase grid-tied inverter stage onto a single regulated 400 V DC bus. A three-phase interleaved boost converter
with variable-step Perturb-and-Observe MPPT manages the PV interface; a dual active bridge converter with single-phase-shift
modulation handles the EV port via a 1 kV-isolation high-frequency transformer; and a three-phase full-bridge bidirectional
inverter employing Space Vector PWM (SVPWM) with a proportional-resonant current controller in the αβ stationary frame
governs three-phase grid exchange at 230 V (L-L), 50 Hz. All switching devices are implemented with 1200 V SiC MOSFETs,
and boost-stage freewheeling is accomplished by SiC Schottky diodes. A hierarchical energy management system solves a
mixed-integer linear programme at 15-minute intervals, co-optimising real-time-pricing arbitrage revenue against a nonlinear
battery degradation cost model. System state and dispatch set-points are communicated via Modbus/CAN fieldbus.
MATLAB/Simulink simulation at 6.6 kW rated power demonstrates peak V2G round-trip efficiency of 95.4%, three-phase
grid current THD of 2.3% under rated injection, MPPT tracking accuracy of 99.2%, and a 19.8% improvement in net daily
arbitrage revenue relative to conventional rule-based time-of-use management. DC-link voltage deviations during mode
transitions are confined to ±10 V, with full settling within 42 ms. The results substantiate idea as a technically rigorous and
economically viable platform for residential and light-commercial solar-EV grid integration.
