电网规划面临的新形势与对策

Discussion on New Situation for Power Grid Planning and Countermeasures

以电网规划工作面临的现状困境为切入点,分析其主要原因在于传统的电网规划工作是确定的、孤立的和单向的,从而导致规划适应性差、实现率低、项目投资效益差等问题。为此,针对电网面临的新形势,论述了国内外经济发展形势、电源发展格局、用户供电要求、电力设备发展和国有企业定位等问题,指出当前的电力系统已处于转型发展时期,电网规划工作需要注重适应性、协调性、可持续性。提出应对新形势的策略为构建规划工作体系、建立规划指标体系、变革规划工作模式、加大外部协调力度、推进大规划进程,并建议对远景目标网架论证、电压层级协调、分布式能源接入和电力市场影响课题进行深入研究。

By taking status quo plight of power grid planning as entry point, this paper analyzes the main reason is that tradi- tional power grid planning is certain, isolated and unidirectional which may result in problems including poor adaptability, low realization rate, poor project investment benefits and so on. Therefore, aiming at new situation for power grid, it discusses economic development situation at home and abroad, power source development structure, power supply require- ments, power equipment development and position of state owned enterprises. It points out that present power system lies in a transformational development period and power grid planning is required to focus on adaptability, harmony and persist- ence. It also proposes strategies for new situation in order to construct planning work system, establish planning index sys- tem, reform planning mode, increase external coordination dynamics and promote large planning process. Meanwhile, it suggests to deeply study topics which may affect prospective target net rack, voltage hierarchy coordination, distributed en- ergy connection and power market.
