Combined Economic Emission Dispatch for Microgrid Considering Solar and Wind Power Cost Functions Using Harmony Search Algorithm

摘要

The Energy Management System (EMS) in microgrids includes the problem of economic dispatch (ED) and environmental economic dispatch which called combined economic emission dispatch (CEED). In this paper, the harmony search (HS) algorithm is employed to solve the environmental economic dispatch problem for the microgrid considering the cost functions of wind power, solar power and battery sources. The test system used in this paper consists of three thermal generators, wind power source, solar power source and battery as energy storage device. To show the effectiveness of the employed method, three different scenarios are used. Also, the results are compared with those obtained by other recently published methods.
