In this paper, we present a co-simulation framework that combines two main simulation tools, one that provides detailed multiple building energy simulation ability with Energy-Plus being the core engine, and the other one that is a distribution level simulator, Matpower. Such a framework can be used to develop and study district level optimization techniques that exploit the interaction between a...
Reducing carbon dioxide emissions is an important issue for protection of the global environment. To achieve this, the spread of photovoltaic generation (PV) has expanded since the start of Feed-in Tariff (FIT) in Japan. However, it is difficult to introduce new renewable energy generation because of restrictions on grid interconnection. This is due to the concerns of voltage deviation, reverse power...
