Embodiment approach

[0077] Explanation of related terms:

[0078] Electricity spot market: the general term for the next day, intraday, and real-time dispatching of electricity trading activities carried out through the trading platform in a day-ahead and shorter period of time. The subject matter of spot market transactions includes electric energy, frequency modulation services, backup services, etc.

[0079] Day-ahead market: An electric energy market that determines the unit combination status and power generation plan on the operation day (D-day) one day in advance of the operation day (D-1 day).

[0080] Intra-day market: the electric energy market that will be traded in the next few hours of the operation day (D day) on a rolling basis.

Embodiment 1

[0082] see figure 1 As described, the present invention proposes a method for early warning of inter-provincial spot market risks, the specific steps of which include:

[0083] S1. Receive an inter-provincial spot market risk early warning analysis request, the request is used to request an inter-provincial spot market risk analysis;

[0084] S2. Obtain real-time data of the power grid in response to the request. The real-time data of the power grid includes operating data, market reporting data and market clearing results. The real-time risk index X of the power market is calculated according to the real-time data of the power grid. The risk indicators include market structure, market operation, and power grid security.

[0085] (a) Market structure

[0086] Reflect the degree of market competition through market supply and demand indicators.

Embodiment 2

[0150] The present invention also provides an inter-provincial spot market risk early warning system, including:

[0151] The determination module, after receiving the inter-provincial spot market risk early warning analysis request, obtains the real-time data of the power grid, and determines the real-time risk index X of the power market according to the real-time data of the power grid;

[0152] The risk early warning module is used to compare the real-time risk index X with the historical risk index Y in the threshold library to carry out risk early warning; if If there is a risk, the risk warning information will be issued; if Then there is no risk. At this time, import the real-time risk indicator X into the historical database, and update the corresponding threshold U in the corresponding threshold database; the threshold U can be set to different thresholds according to different risk indicators; according to experience, the preferred range of threshold U is 0.15 -0...

Abstract

The invention discloses an inter-provincial spot market risk early warning method and system, and the method comprises the following steps: obtaining the real-time data of a power grid after receiving an inter-provincial spot market risk early warning analysis request, and calculating a real-time risk index X of a power market according to the real-time data of the power grid; and comparing the real-time risk index X with a historical risk index Y in a threshold value library, and carrying out risk early warning. According to the invention, the market operation state can be monitored in real time, various operation risks of the market are identified, the possible damage degree caused by the risks is evaluated, an alarm prompt is given, the risks are planned and purposefully managed and controlled, stable and healthy operation of a power grid is guaranteed, and the stability of power supply is guaranteed to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of electric power market, and in particular relates to a risk early warning method and system for an inter-provincial spot market. Background technique [0002] In recent years, the construction of the power grid with the UHV power grid as the backbone grid and the coordinated development of power grids at all levels has been continuously accelerated. base and carrier. Especially as the proportion of installed capacity of clean energy continues to increase, considering the intermittent and volatile characteristics of renewable energy such as wind power and photovoltaic power generation, the use of inter-provincial spot trading platforms to promote the large-scale consumption of clean energy is the construction of the power spot market. one of the important goals. [0003] The risk management and control of the power spot market is an important part of the operation of the power spot market and an important...
