A monthly cross-provincial renewable energy consumption method and terminal equipment

Abstract

The invention discloses a method and terminal equipment for monthly cross-provincial renewable energy power consumption. The method includes: setting the consumption weight up to the standard value of the current month in the province where the province is located; estimating the demand for renewable energy power in the current month; establishing different constraints According to the corresponding relationship between conditions and transaction decision items, the transaction decision items under different constraints are sorted; the sorted transaction decision items are combined to filter out optional transaction data items that meet multiple constraints at the same time, and according to The power purchase cost and priority rules sort the optional transaction data items, and select multiple transaction data items according to the order of power purchase cost from low to high according to the renewable energy power demand of the province in the current month; the present invention uses the transaction model Dynamically adjust the actual monthly transaction data items under multiple constraints, improve the accuracy and rationality of the actually consumed renewable energy power data, and increase the consumption of renewable energy power while taking into account the cost of power purchases ability.

Description

technical field [0001] The invention belongs to the technical field of renewable energy consumption and power supply, and more specifically relates to a method and terminal equipment for monthly cross-provincial renewable energy consumption. Background technique [0002] In recent years, the state has successively issued a series of policy documents on promoting the high-quality development of renewable energy and effectively solving the problem of clean energy consumption, and formulated the weight of the responsibility assessment of renewable energy consumption for the assessment subjects of each province. For the provincial power grid companies, how to carry out inter-provincial and inter-regional renewable energy power transactions under the new policy environment to adapt to the power market management strategy under the renewable energy power consumption guarantee mechanism has become an urgent problem to be solved. [0003] Existing literature studies mostly focus on ...

Problems solved by technology

[0003] Existing literature studies mostly focus on the power generation and dispatch of renewable energy, hoping to optimize the peak-shaving timing of pumped-storage units, thermal power units and hydropower units, and maximize the consumption space of non-hydro renewable energy generation to promote renewable energy. Energy consumption, but this method requires a large number of generating units to cooperate with the construction, and its engineering and management costs are huge

At present, in the actual implementation process of renewable energy power consumption, the power grid companies usually set the amount of renewable energy power consumption artificially according to the province's annual assessment weight and demand formulated by the state. However, the consumption of renewable energy power The amount will be affected by factors such as climate conditions, power trading cycle, power trading varieties, and external power supply. However, the artificially set renewable energy power consumption is not accurate and reasonable, resulting in actual consumption and expected consumption. There is a large deviation between them, and the consumption capacity is not fully utilized during the period when the power transaction is smooth, resulting in the failure to complete the assessment indicators on time
