Heat recovery for Combined Heat and Power (CHP) applications has been developed and fully integrated into a Capstone® Micro Turbine™ Distributed Energy Resource (DER) power generation system. The Capstone C6XiCHP Series Micro Turbine products have the ability to generate up to 65 kW of electrical power and 120 kW of thermal heat recovery in a fully integrated single package. Users are able to scale up to 2.0 MW of electrical power generation combined with up to 3.6 MW of heat energy when the C6XiCHP in applied in multiple unit (MultiPac™) arrays. Because multiple units are used and operated as a single generator system, users can operate each individual C6XiCHP at full load efficiency and turn off unused C6XiCHP units to follow site demand without incurring efficiency penalties associated with part-load operation.

Micro turbine (MT) is characterized with complex dynamics, parameter uncertainties, and variable working conditions. In this paper, a novel robust controller is investigated for a single-shaft micro turbine as a distributed energy resource by integrating a feedback domination control technique and a feedforward disturbance compensation. An active estimation process of the mismatched disturbances is firstly enabled by constructing a disturbance observer. Secondly, we adopt a feedback domination technique, rather than popularly used feedback linearization methods, to handle the system nonlinearities. In an explicit way, the composite controllers are then derived by recursive design based on Lyapunov theory while a global input-to-state stability can be guaranteed. Abundant comparison simulation results are provided to demonstrate the effectiveness of the proposed scheme, which not only perform an improved closed-loop control performance comparing to all existing results, but also render a simple control law which will ease its practical implementation.

This paper presents a user-friendly design method for accurately sizing the distributed energy resources of a stand-alone microgrid to meet the critical load demands of a military, commercial, industrial, or residential facility when utility power is not available. The microgrid combines renewable resources such as photovoltaics (PV) with an energy-storage system to increase energy security for facilities with critical loads. The design method’s novelty complies with IEEE Standards 1562 and 1013, and addresses resilience, which is not taken into account in existing design methods. Several case studies simulated with a physics-based model validate the proposed design method and demonstrate how resilience can be included in the design process. Additionally, the design and the simulations were validated by 24 h laboratory experiments conducted on a microgrid assembled using commercial off-the-shelf components.
