发电侧储能应用

随着新能源的并网，风光的波动性和随机性使得电网短时间内的能量不平衡加剧，传统能源由于调频速度慢，在响应信号时具有滞后性，因此不能满足新增的需求，而储能由于调频速度快，容量可调，因此成为非常好的调频资源。火电厂增加储能系统后，实际应用中可有效提升 Kp 值，提高电厂收益。The fluctuation of power grid result from short period heavy load access such as from steel plants and glass factories would greatly affects the operation of other power equipment. The container energy storage system can meet the fast response requirements of primary frequency and voltage modulation, to respond to short period load power changes. After the thermal power plant has increased its energy storage system, it can effectively increase the KP and plant revenue.

微电网应用

某些偏远、无电网地区由于人口较少，离主干电网线路较远等原因，通常需要自建电网。采用新能源发电并使用微电网技术即是一种较好解决方案。Some remote, non-grid areas usually require self-built power grids because of their small population and their long distance from the main grid lines. Using new energy to generate electricity and using microgrid technology is a wise solution.

• 根据当地环境特点可利用太阳能、风能、小水能、油机等多种形式发电，同时通过储能系统平滑发电量和用电量，或者通过新能源发电与市电互补形式，使得供电稳定性大大提高

• According to the local environment characteristics, it can use solar energy, wind energy, small water energy, oil generators and other forms of power generation. At the same time, smooth power generation and electricity consumption through energy storage systems, or through the complementary form of new energy generation and utility power, makes the power supply more stable.
