摘要/Abstract

摘要： 安全校核是保障区域电网安全运行和区域内电力市场正常运营的重要技术环节。当前区域电网范围内已呈现电力现货试点省与非试点省并存、省间交易电量与计划电量交织的复杂形态，倒逼电网运行组织者必须创新提出与之相适应的安全校核机制。首先总结分析国外典型单一市场形态下电力市场出清和跨市场/跨国电力交易的电网安全校核机制架构及其借鉴意义，揭示中国复杂市场环境下区域电网安全校核的现实基础、特殊约束与需求，在此基础上设计了与中国近期电力市场形态、现行电力调度管理体制、区域电网结构等相适应的跨省跨区电力中长期交易、区内各省日前市场预出清发电计划和非现货试点省日前发电计划的安全校核机制架构。对于跨省跨区电力中长期交易，提出了基于跨区交易电力曲线典型场景集的电力校核方法和提高安全校核频次的安全校核机制改进方案；针对构建区内日前发电计划安全校核机制，提出了适应复杂市场环境的3种可选择方案，在对比分析三者特点的基础上，给出了方案实施路径建议。

Abstract: Security analysis is an important part of both the safe operation of regional power system and the normal operation of electricity market. At present regional electricity system in China has come to the complex situation with coexistence of regulation and deregulation, and interweaving of inter provincial transaction energy and planned electricity quantity, which compels the system operators to formulate corresponding security analysis mechanism. Firstly, this paper summarizes the power system security analysis mechanism for the single-mode market clearing and cross-market (country) electricity trading of foreign countries, and then explores the realistic basis, special constraints and requirements for regional power grid security analysis under the complex market environment in China. On this basis, a new security analysis mechanism framework adaptable to existing electricity market form, current power dispatching management system and regional power grid structure is designed, which includes the medium and long-term trans-province(region) electricity trading, day-ahead market pre-clearing generation plan of the pilot provinces and the day ahead generation plan of the non-pilot provinces. For the trans-province and trans-region medium and long-term transactions, this paper put forwards a power checking method based on the typical scenario set of cross-region transaction power curve and an improved security analysis mechanism scheme to elevate security analysis frequency. For the day-ahead period, it puts forward three alternative schemes adaptable to the complex market environment. Based on the comparative analysis, the implementation path of the scheme is proposed.

Key words: complex market condition, regional power grid, security analysis, mechanism design, medium and long-term electricity trading, spot trading
