2サイト地域エネルギーシステムにおけるコージェネレーションユニットの非線形制御

―電気およびガスフローの同時調整

抄録

This paper is concerned with coordinated control of combined heat and power (CHP) plants for regional-scale energy management. The objective of the control is to regulate electricity and gas ｆｌows (energy flows) through an regional energy system with two CHP plants. In order to manage energy imbalances of demand and supply inside the region, the gas flow is indirectly regulated with tracking control of boiler pressure to a suitable reference trajectory. The output tracking controller is designed by the input-output linearization of a nonlinear state-space model of the energy system. Effectiveness of the proposed controller is established with numerical simulations under a practical set of system parameters.
