Optimal operation of thermal generating units and smart houses

Recently, the deregulation and liberalization in power market increase the competition in retail and power sector. Therefore power company needs to reduce operational cost and maximizes the profit by operating generator with higher efficiency. On the other hand, energy consumption is increasing rapidly due to the proliferation of all-electric houses. So the controllable loads, such as electric water heater, heat pumps, and electric vehicles are introduced to power systems. In this paper, the controllable loads, such as heat pump and electric vehicle, are introduced. Moreover, thermal units and the controllable loads are operated in coordinated manner to reduce the total cost of thermal units in the supply side. In demand side, the configuration of electric cost based on the interconnection point power flow is introduced to reduce the electric cost in demand side. Simulation results show the validation of the proposed method and validate the performance and effectiveness of the proposed algorithm of thermal units in supply side and the configuration of electric cost in demand side.
