Primary Frequency Regulation With Load-Side Participation—Part I: Stability and Optimality [PDF]
IEEE Transactions on Power Systems, 2017 We present a method to design distributed generation and demand control schemes for primary frequency regulation in power networks that guarantee asymptotic stability and ensure fairness of allocation. We impose a passivity condition on net power supply variables and provide explicit steady-state conditions on a general class of generation and demand ...

Primary Frequency Regulation With Load-Side Participation—Part II: Beyond Passivity Approaches [PDF]
IEEE Transactions on Power Systems, 2017 We consider the problem of distributed generation and demand control for primary frequency regulation in power networks, such that stability and optimality of the power allocation can be guaranteed. It was shown in Part I of this work, that by imposing an input strict passivity condition on the net supply dynamics at each bus, combined with a ...
