OPTIMAL OPERATION OF SOLAR/WIND TURBINE SYSTEM COMBINED WITH BATTERY USING MIXED-INTEGER LINEAR PROGRAMMING

Abstract

In recent years, renewable energy was increasingly developing and
becoming a trend, it became popular in the power system. As a result, many
problems arise such as the operating time of the sources needing to be allocated
reasonably, and how to trade energy appropriately,... Therefore, in this article,
we have calculated the optimal power distribution for a microgrid system
consisting of a solar panel, a wind turbine, and storage batteries by using the
Mixed-integer linear programming (MILP) method. The objective function of the
problem is to determine the day-ahead hourly capacity of the sources, and the
charging and discharging capacity of the storage battery so that the profit from
the system is the largest when the power price changes during the day. From the
simulation results, it is shown that using the MILP method brings reliable results,
proving it is feasible in reality.
