Finite-state-machine-based electric power simulation software time sequence state conversion method and system

Abstract

The invention relates to a finite-state-machine-based electric power simulation software time sequence state conversion method, comprising: step A) determining the type and the content of a simulation market including step A-1) determining the market type of the market to be simulated, or rather, whether the market has an electric power market, an auxiliary service market, a capacity market and a power transmission right market; and A-2) determining the functions of the various markets and the contained services, especially clarifying the content contained in the auxiliary service market; and step B) according to the finite state machine, determining the time sequence of the market including B-1) determining all the state sets of the market; B-2) determining all the input sets of the market; and B-3) determining the state conversion rule. The method and the system of the invention are based on a finite state machine to realize the electric power market state conversion. In the practical applications, the modes of a state machine are used at a higher frequency, and can be used for state switching of different markets, especially under the condition of repetitive switching of the market states. The method and the system are highly automatic and can work without the guard of people. Therefore, the method and the system are suitable for a multi-node system for medium and long term market simulation.

Description

technical field [0001] The invention relates to the technical field of power system simulation software, in particular to a method and system for time series state transition of power simulation software based on a finite state machine. Background technique [0002] The marketization of power operation will be the general trend. The operation of the electricity market is a complete system with multiple transactions concurrently, long-term and short-term parallel, and interrelated. The marketization of this complex system is inseparable from the software simulation of the electricity market. Some practical problems are predicted and solved. In the power market simulation operation, one of the problems that need to be solved is the power market step size sequence and state conversion. Due to the different ranges of power demand fluctuations, the types of markets that need to participate in power trading are also different, so there is a need to switch between various markets...

AI Technical Summary

Problems solved by technology

[0014] 1) The system will be in a certain state;

[0015] 2) The number of states is limited;

[0019] The traditional process control method can only sequentially convert each state of the electricity market, follow the pre-set logic, and execute from the beginning to the end. In the electricity market, there will be repeated switching between each time scale and market type. one-way state change
