受调峰和安全稳定约束的华东电网新能源承载规模研究
摘要：随着“十四五”新能源布局向中东部倾斜，中东部的新能源发展速度高于西部、北部地区，对受端电网新能源承载能力的研究变得越来越迫切。文中针对华东受端电网，提出了一种评估新能源承载规模上限的方法。该方法依托中国电科院研发的生产模拟软件，统筹直流规模、弃电率、交流断面限制、储能应用等因素，在满足电力电量平衡、调峰平衡等约束前提，优化求解各类电源开发规模，求得受调峰约束的新能源发展上限；依托综合仿真试验研究系统(Power system department-bonneville power administration, PSD-BPA），兼顾直流规模、直流功率敏感性，在满足单一直流功率缺额不触发低频减载、第一级安全稳定标准等约束条件，利用时序仿真法求得受频率稳定、电压稳定约束的新能源发展上限；通过比较论证，提出制约华东电网新能源规划发展的主要影响因素、承载规模和应对措施。
Abstract:As the layout of new energy during the 14th Five-Year Plan is inclined to Central and Eastern China, the development speed of new energy in Central and Eastern China will be higher than that in Western and Northern China, so it leads to more and more urgent to study the power-carrying capacity of new energy in the receiving-end power grid. In allusion to East China power grid that was regarded as typical receiving-end power grid, a method to evaluate the upper limit of new energy power-carrying capacity was presented. Firstly, relying on the electricity production simulation software which was independently developed by China electric power research institute, fully considering such factors as the scale of DC transmission, the abandoned electricity rate, the exchange section restrictions and energy storage application, in the context of satisfying the constraints of electric power and energy balance and peak balance the development scale of all kinds of power supply was optimally solved, thereby the upper limit of new energy power-carrying capacity constrained by peak-shaving was obtained. Secondly, based on the comprehensive simulation system called PSD-BPA, considering both the sensitivity of DC power and that of DC transmission scale, under the constraints of not triggering low-frequency load reduction by power vacancy of single DC transmission and satisfying the first level of security and stability standard, the timing simulation method was utilized to respectively obtain the upper limit of new energy power-carrying capacity constrained by frequency and voltage stability. Finally, by means of comparison and demonstration, the important influencing factors, power-carrying capacity and countermeasures restricting the development of new energy in East China power grid were proposed.
