Optimal operation of thermal generating units and smart houses considering transmission constraints

Due to the deregulation and liberalization in power market, thermal unit commitment program is researched and developed in the world wide. On the other hand, fuel exhaustion and global warming is increasing, therefore, the renewable power plant is introduced to the power system. The generated power of the large capacity renewable energy plant reads to the violated transmission constraint in thermal unit commitment program, therefore, the transmission constraint should be considered. This paper focuses on the optimal operation of the thermal units incorporated controllable loads such as electrical vehicle (EV) and heat pump (HP) considering the transmission constraints. The proposed method is compared with the power flow in thermal units operation without controllable loads and the optimal operation without the transmission constraints. Simulation results show the validation of the proposed method and validate the performance and effectiveness of the proposed algorithm of thermal units in power supply side and the controllable loads in demand side.
