Analysis of housing load with the assumption of using equipped accumulators

In order to expand PV systems smoothly and solidly, more than 320 PV systems are installed to the demonstrative test sites. In those residences, people live a normal life and load characteristics differ with residences. This is caused by the differences in square measure of residences, lifestyle, the personal organization of the family, used electrical equipment, contract with electrical power company. To consider using the output suppression avoidance system (PV+ battery) developed in this research, the pattern of housing load, which changes by many factors is an important element which can´t be ignored. If such a use is carried out, residence loads are provided from PV in the daytime and are provided from batteries in the nighttime. In considering the use the output suppression avoidance system, it is important to grasp electric power of residence loads for the daytime and the nighttime individually
