Analysis of Hybrid Power Generation System Combining Synchronous Generator and PV Array

In renewable energy generation systems, the hybrid configuration of synchronous generators with photovoltaic arrays is increasingly becoming a research focus. This integration approach fully leverages the advantages of both power generation technologies, enabling more stable power output. Code implementations typically involve power flow analysis algorithms and real-time power management systems to coordinate energy distribution between these sources.

As traditional power generation equipment, synchronous generators possess excellent inertial response and frequency regulation capabilities. When system frequency fluctuates, synchronous generators can automatically provide short-term power support through their rotational inertia. In contrast, photovoltaic power generation relies on inverter grid connection, lacking mechanical inertia but offering advantages of high efficiency and low maintenance costs. Control algorithms for synchronous generators often incorporate governor systems and automatic voltage regulators (AVR), while PV systems require maximum power point tracking (MPPT) algorithms and inverter control logic.

In practical applications, this hybrid system typically needs to address several key technical issues. The first is power distribution strategy, which requires real-time adjustment of output ratios from both power sources based on grid demand and lighting conditions. This can be implemented through droop control algorithms or optimization-based dispatch controllers. The second is voltage regulation mechanism, since photovoltaic power fluctuations may affect grid voltage quality, while synchronous generators can provide voltage support through excitation control systems using PID regulators or advanced fuzzy logic controllers.

System stability is another crucial consideration factor. The intermittency of photovoltaic generation may cause power fluctuations, while the integration of synchronous generators can buffer these fluctuations, enhancing the grid's disturbance resistance capability. Particularly under weak grid conditions, the presence of synchronous generators can significantly improve the system's short-circuit capacity and voltage stability. Stability analysis often involves eigenvalue calculation methods and transient stability simulation codes to assess system damping characteristics.

Future development trends will focus on intelligent control algorithms, achieving optimal coordination between both power sources through advanced control strategies, while exploring application possibilities of energy storage systems in hybrid power generation. Model predictive control (MPC) and artificial intelligence-based optimization algorithms represent promising directions for implementation. This hybrid power generation model provides a viable solution for achieving high-proportion renewable energy grid integration, requiring sophisticated energy management system (EMS) software architectures with real-time data processing capabilities.
