250kwAC/DC+250kwDC/DC
PCS energy storage converter
Overview: At present, the traditional grid power supply is used. In order to "peak cutting and valley filling"reduce the cost of electricity, promote the stability of electricity consumption, dynamic capacity increase, optimize the power demand response, strengthen the emergency power protection of important loads, better realize the new power supply model of the combination of photovoltaic and grid power in the factory, integrate automation, information, intelligent, interactive and new technologies, and build a set of energy storage system. Provide enterprises with "peak cutting and valley filling" electric energy storage contract energy management services, reduce comprehensive electricity costs, and build user-side energy storage projects. Enable enterprises to upgrade from the original traditional grid power consumption mode to the multi-energy complementary energy consumption mode integrating "grid power + energy storage + photovoltaic power generation", fully optimize the energy structure of the plant, and promote the healthy and orderly development of new regional energy storage. The power structure of the plant will be upgraded from "single grid power supply mode" to a new mode of "grid power + energy storage + photovoltaic power generation", which is in line with the new power system operation architecture, and at the same time, it will be gradually implemented with the photovoltaic power generation network in the plant to form a comprehensive functional system of "grid power + energy storage + photovoltaic power", and improve the autonomous controllable ability of the whole industrial chain of the plant and the level of green development. Through the integrated energy control system platform of the factory, we provide an effective overall energy system control solution, realize the convenient supply and management of comprehensive energy in the factory, and create a convenient, safe, green and efficient new generation of low-carbon factory. The 250kwAC/DC+250kwDC/DC PCS energy storage converter independently developed by Hebei Tongdian Electric plays a major role in the system.
