Robustness Analysis of PI Controller to Constant Output Power with Dynamic Load Condition in DC Nanogrid System

摘要

Various modern life support systems, almost all people need electrical energy. In the use of large quantities and continuously will experience an energy crisis or an end to the supply of BBM (Oil Fuel) or fossil energy. Where fossil fuels cannot be renewed and will easily run out. So alternative energy is needed, namely with solar heat, so the right solution to overcome this problem is by using photovoltaics which are renewable energy. Various modern life support systems, almost all people need electricity. In the conditions described above, alternative energy is used as substitution for one solution or several life support systems. And the solution is to use electric stoves with alternative energy, namely solar energy. In this final project, solar energy is used as an energy test. alternative. This experiment uses 8 pieces of photovoltaics, each of which is 135 WP 40-60 Vdc to supply electrical energy on an electric stove of 220Vdc with a power of 200-600 W. At power settings can be done in two ways, linear or step , which is used in this final project, that is, in order. In electrical energy generated from photovoltaics at 1080 WP in the form of 200-300 Vdc of electrical energy and raised using boost converter by regulating basic switching, the control used is PI Controller to maintain dc voltage output. This voltage is used to supply electric stoves.
