Embodiment Construction

[0023] An economic operation strategy of multi-energy complementary micro-energy, first establishes an economic goal, chooses the operation mode that minimizes the overall cost or maximizes the benefit, and does not consider non-productive factors such as the impact on the performance of the power grid and the impact on the environment in the objective function. economic parameters.

[0024] Secondly, establish an economically optimal objective function, that is, the objective function is to minimize the daily operating cost of the multi-energy complementary micro-energy system (or maximize the daily gross profit, here the minimum operating cost is taken as an example), and the daily operating comprehensive cost of the micro-energy system mainly includes Fuel cost, power cost for interacting with the grid, and system operation and maintenance costs in three aspects:

[0025] min K Total =min(K Fuel +K Grid +K Maintain ) (1)

[0026] In the formula: K Total is the compreh...

Abstract

The present invention relates to an economic operation strategy of a multi-energy complementary micro energy. The strategy is characterized by establishing an economic objective function, selecting an operation mode which can minimize the overall cost or maximize the gain, and not considering non-economic parameters such as impact on power grid performance, impact on environment, and the like, in the objective function; and establishing economic optimal objective function, wherein the objective function can minimize the daily operation cost of the multi-energy complementary micro-energy system, and the daily operation comprehensive cost of the micro-energy system comprises three aspects of fuel costs, power costs generated by interacting with the power grid, and system operation and maintenance costs.

Description

technical field [0001] The invention belongs to the field of power generation control and relates to an economical operation strategy of multi-energy complementary micro-energy. Background technique [0002] With the continuous deepening of energy reform, the micro energy network composed of clean energy and renewable energy forms such as distributed photovoltaic, wind power, micro gas turbine, biomass power generation, solar thermal and energy storage through different forms and management units is The current development direction of energy technology. The solar-storage integrated system composed of distributed photovoltaics and energy storage or the wind-solar-storage system composed of wind power, photovoltaics and energy storage solves the problem of on-site utilization of wind energy and solar energy on the demand side, effectively avoiding "abandoning wind and solar energy". "Phenomenon, at the same time, in the case of peak-valley time-of-use electricity prices, thr...
