Abstract

The invention relates to the technical field of electric system energy planning, in particular to a random production simulation algorithm suitable for intermittent energy access. The random production simulation algorithm suitable for the intermittent energy access comprises the following steps that: establishing the time sequence load model of a system, forming an original load time sequence curve, establishing a conventional energy simulation submodel according to the characteristics and the operation situation of a conventional energy power station, and meanwhile, according to the output situations of a photovoltaic power station and a wind power plant, establishing an equivalent multi-state unit model; adopting the established photovoltaic and wind power equivalent multi-state unit model, correcting an equivalent electric quantity function, and calculating photovoltaic generating capacity and wind power generating capacity; and finally, after all units finish being arranged, calculating system production cost, EENS (Expected Energy Not Supplied) and LOLP (Loss Of Load Probability), and ending a random production operation simulation process which contains intermittent energy.

Description

technical field [0001] The invention relates to the technical field of power system energy planning, and more specifically, relates to a stochastic production simulation algorithm suitable for intermittent energy access to a power grid. Background technique [0002] Facing the depletion of traditional fossil energy and the deterioration of the ecological environment, intermittent energy such as wind power and photovoltaics has been favored by countries all over the world because of its environmental friendliness, low pollution and renewable characteristics. my country is a big energy consumption country. At present, energy consumption is still overly dependent on fossil energy such as coal, oil, and natural gas. Therefore, the development of new energy has become a strategic choice for my country to achieve sustainable energy utilization and energy security. Encouraged and supported by national policies, my country's new energy power generation has developed rapidly in the p...

Problems solved by technology

In addition, the conventional energy models used in some production simulation algorithms are relatively outdated, which cannot accurately reflect the current operating conditions and output characteristics of each power station

The equivalent power function method is a typical traditional production simulation algorithm. This algorithm converts the time-series load curve into a continuous load curve, and obtains the power function from the continuous load curve. Finally, it uses the modified power function and convolution algorithm to complete The power generation of the power station is scheduled to work, but the equivalent power function method loses the timing information of the load, and cannot take into account the impact of the unit's operating state switching
