摘要:直流输电互联电网形成的区域间多能源发电互补,能够解决大规模弃风、弃光和电力出力与分配不均,提高可再生能源利用率。文章分别分析了直驱式风电场、MMC、多端口DC/DC及LCC等关键组网设备的运行控制策略,组建了LCC与含新能源的多端直流电网互联系统,分析了其结构特点和优势,提出了相应的系统启动和功率协调分配控制策略。在PSCAD/EMTDC平台搭建了仿真模型,仿真结果验证了所提出的协调控制策略的有效性。
The construction of DC interconnected power grids will create complementary inter-regional multi-energy power generation, which can solve the problems of large-scale abandoned wind and photovoltaic power, benefit uneven power output and distribution, and improve the utilization rate of renewable energy. The paper analyzes the operation control strategies of crucial network equipment such as direct drive wind farm, MMC, multi-port DC/DC and LCC, and establishes a multi-terminal DC grid interconnection system with LCC and new energy, and analyzes its structural characteristics and advantages. Corresponding control strategies of the system startup and power coordination allocation are proposed. The simulations built under the PSCAD/EMTDC platform verify the effectiveness of the proposed coordinated control strategy.
