英文要約Title : R&D of Practical and integrated Energy storage systems for smart community / Elemental technology development / R&D of Demandresponsible PV and battery powergeneration system.
Tens of kW size for Demandresponsible battery system set close to consumer side like housing complex or office building has been studied. However, since power conditioners are designed individually , the cost can not be reduced. On the other hand, higher consciousness for the environment increases the case of introducing photovoltaic(PV) power generation systems in housing complex or office building. The further spread of the system is expected. The photovoltaic(PV) power generation systems is an unstable system because it is easily affected by the weather condition. It is know that the spread of the system will become a factor for the voltage rise and frequency error of power grid lines. In addition, the battery system can not only discharge , but also charge to make the electric power fractuations smaller. We assume PV and battery powergeneration system will solve the problem , but the system control technology and required performance for the system are not established. And the approach to make the system cooperate with power grid lines by the power supplier's requirement has not been performed. Our purpose is to verify the system control technology and required performance for the system, provide the interface that will control the power supply and demand. That will contribute the spread of renewable energy, make power grid lines stable and cooperate with it. To think about the entire system, we simulated available size of solar panel and the necessary size of the battery from the location and its environment , then calculated the power generation and efficiency on various type of patterns. And we simulated the efficiency of the system selected by 2 types of battery and 2 types of solar panels. Next, we introduced the equipment based on the required performance by the simulation. That is to select the number of power conditioners, to cooperate by the external directions (battery SCADA, Distributing device) and to generate the planned power by the location demand. And that will verify the required performance to control PV and battery powergeneration system, total system and the battery. Required performance, system control technology , developing the system and battery and the test in the local area will allow us to establish the PV and battery powergeneration system.
