DESCRIPTION
An electronic control device has been developed to control an alternator driven by a free-piston Stirling engine, which lacks position and/or frequency sensors for oscillating parts of the engine. This device implements a control method that ensures the free-piston Stirling engine with a linear alternator (FPSE-LG) maintains a constant equilibrium between the thermal power input to the engine and the electrical power output from the linear alternator.
The electronic device is capable of starting, operating, and controlling the Stirling free-piston engine in complete safety, making it suitable for grid-connected applications as well as stand-alone systems.
Additionally, the device consists of bidirectional electronic converters, enabling the integration of power generation systems and energy storage systems, such as rechargeable batteries and/or flywheels, which can be managed through a centralized or decentralized control system.
The device is also applicable in micro-cogeneration, including residential environments, to exploit renewable energy resources, including biomass.
Furthermore, the device can meet both electrical and thermal demands for off-grid homes. It allows for easy integration with cloud-based ICT systems and IoT devices, making it compatible with integrated energy communities and peer-to-peer energy exchange.Incentivi per la valorizzazione economica dei brevetti Decreto Direttoriale 26 novembre 2019″ e viene ammessa a finanziamento con PROJECT PLAN N.
