[0004] At present, subject to the limitations of the current technical level, cross-regional and cross-provincial power transactions are generally determined according to the needs of supply and demand balance, which lacks both overall optimization and optimization in terms of power purchase costs and environmental protection requirements. The technical means of quantitative analysis to achieve the maximum economic benefit

Embodiment
[0033] 1) Based on the power grid model, a simplified network model is constructed.
[0034] Such as figure 1 As shown, the equivalent method is adopted, and the provincial power company is equivalent to a node, and the inter-provincial contact lines are equivalent to a section. For example: In this case, the five regions of the model represent the five regions of Northeast China, North China, Northwest China, Central China and East China, and all provinces within the five regions.
[0035] 2) According to different transaction modes, set optimization scenarios, including the scope of optimization, which is reflected in the subjects participating in the optimization and the transaction path of power exchange,
[0036] In this example, two transaction modes are set, namely:
[0037] ① Hierarchical organization, that is, the headquarters organizes cross-regional transactions, and regional organizations organize cross-provincial transactions.
[0038] According to the balance ...

The invention relates to a method for optimizing medium and long term trans-regional trans-provincial deals and assessing the modes of the medium and long term trans-regional trans-provincial deals. The method for optimizing the medium and long term trans-regional trans-provincial deals and assessing the modes of the medium and long term trans-regional trans-provincial deals is characterized by comprising the steps of (1) building a network model, (2) setting an optimization scene according to the different modes, (3) setting optimization parameters, (4) building an optimization model, (5) carrying out optimization calculation, and (6) carrying out comparison, analysis and assessment. The method studies and tries the optimization and assessment of the medium and long term trans-regional trans-provincial deals under the actual power grid operation data, finds out a deal strategy with the priority of economical benefits or comprehensive benefits as a target based on simplification of a power grid model, and carries out optimization and assessment of the medium and long term trans-regional trans-provincial deals, thereby bringing certain guide significances on improving the economy, safety and standardability of a deal scheme. The method can relieve the power shortage situation through trans-regional trans-provincial deals when the power structures in electric energy areas are different, realizes optimized distribution of electricity in a larger range, compensates the shortage through the surplus among the areas, and effectively relieves the imbalance between supply and demand in the areas short of power supply.
Description
technical field [0001] The invention belongs to the field of electric power automation, and in particular relates to a medium- and long-term trans-regional and trans-provincial transaction optimization and mode evaluation method. Background technique [0002] Due to the large difference between the distribution of primary energy and the level of regional economic development, the power supply capacity of each region cannot fully match the power demand. Therefore, it is necessary to achieve effective regulation of power resources through cross-regional transactions of power; There are large differences in price levels, and cross-regional energy transactions have certain economic benefits; in addition, in the medium and long-term stage, due to the differences in the power supply structure of various energy regions, such as provinces with high hydropower ratios, during the wet season, you can pass Trans-provincial transactions alleviate the power shortage in provinces with high...
