PERANCANGAN DAN PEMBUATAN LOAD SHARING PADA SISTEM DC MICROGRID

Microgrid is a load interconnection system which of a power distribution that comes from renewable energy, conversion of conventional energy (fossil) to renewable energy (sun, wind, water, etc.) is one way to reduce environmental pollution. Apart from fuel consumption for power plants that use conventional energy not always available on this earth, alternative energy is needed as a replacement.
Problems that are often found in DC Microgrid networks, one of which is error current sharing, the beginning of this problem occurred in a system of two microgrid DC generators when power sharing, the power distributed to the load was not balanced. In general, there are two factors, namely the resistance of the cable (Rline) and the different characteristics of the inductor, capacitor, diode and others even though the brand is the same. So this is what causes the difference when power sharing. The solution is to use a droop control or droop resistance which aims to increase the distribution of current and power in order to minimize the difference between error current sharing and error power sharing.
