摘要
新型电力系统重塑了能源生产消费结构,电力市场机制也需随之改变。首先,分析指出提升系统调节能力是新型电力系统下市场机制设计的首要目标;围绕该目标给出了市场机制应具备的特点,包括利于激发调节动力、释放调节能力、接纳各种新型调节资源等。其次,对世界各国现货市场普遍采用的分时交易机制进行了分析,指出其与新型电力系统存在诸多不适应之处,包括市场主体调节贡献无法被量化表征,市场主体连续运行特性与分时交易机制相矛盾、调节能力难以完全释放,以及难以满足海量柔性资源直接参与电力市场的需求等。为此,文中舍弃分时交易的方式,转而提出整体交易机制与电力互替品概念,介绍了形成与交易电力互替品的主要思路,并以电力互替品为核心构想了新型市场机制。该机制可通过调节责任划分量化各主体调节贡献,激发市场主体的调节动力;同时,也能促进市场主体主动优化自身运行方式,释放调节能力;具有易于扩展的优势,可轻松接纳新型电力系统下层出不穷的各类新型主体。
The new power system has reshaped the structure of energy production and consumption,and the electricity market mechanism also needs to change accordingly.First,this paper points out that the improvement of system flexible adjustment capability is the primary goal of the market mechanism design for the new power system.Characteristics of the market mechanism that can achieve this goal are given,including stimulating the adjustment motivation,unleashing the adjustment capability,and accommodating various new flexible resources.Then,the time-of-use trading mechanism that is generally adopted in the spot markets of various countries in the world is analyzed and its many incompatibilities with the new power system are pointed out,including that the adjustment capability contribution of market entities cannot be quantified and represented,the continuous operation characteristics of market entities are inconsistent with the time-of-use trading mechanism,resulting in difficulty in fully unleashing the potential adjustment capability,and it is difficult to meet the demand for massive direct participation of flexible resources in the electricity market.Therefore,this paper abandons the method of time-of-use trading and instead proposes the concept of holistic trading mechanism and substitute power product.The main ideas for forming and trading substitute power products are introduced,and a new market mechanism is conceived with the substitute power product as the core.This mechanism can quantify the adjustment contribution of market entities by assigning the adjustment responsibilities,and stimulate the adjustment motivation of market entities.Meanwhile,it can also promote the market entities to actively optimize their own operation methods and unleash adjustment capabilities.Furthermore,it has the advantage of being easy to expand and can easily accommodate various new market entities in the new power system.
