Problems solved by technology
The traditional control is designed with the lowest power supply cost and the best new energy consumption as the optimization goal, which deceives the power users in various flexible power consumption methods, which is not conducive to the balance and optimization of the interests of the source, network, load and storage parties, and fails to realize the entire source, network, load and storage economy. and maximize social benefits
[0005] Considering the continuous access of integrated energy and adjustable loads, the existing research considers flexibility measures relatively single, and it is difficult to meet the flexibility needs of high-proportion new energy grid-connected consumption, and the flexibility modeling of traditional grid structures is complicated. The consumption model is difficult to solve efficiently
Since the single control strategy is often accompanied by its inherent limitations, such as the large amount of calculation of the centralized control leads to its limited response speed, and the lack of information interaction of the decentralized control makes its regulation cost unable to be effectively reduced, which makes it difficult to balance the single control strategy. Rapidity and economy of regulation

Embodiment
[0035] Embodiment 1 of the present disclosure introduces a new energy comprehensive consumption and scheduling method based on source-network load-storage coordination.
[0036] Day-ahead scheduling is to predict the output and load of new energy on the scheduling day through historical data and the weather forecast on the scheduling day, and then formulate the scheduling day plan based on the historical data. Maintaining the balance of the entire power system requires the output of wind power, photovoltaics, thermal power and other power sources, and then superimposed the losses of power grid lines and transformers. At the same time, according to the fixed load demand of power users, first ensure the full consumption of the maximum output of wind power and photovoltaics. System power balance, real-time adjustment of the power controllable user load adjustment capacity, adjustment of the charging and discharging state quantities of the energy storage system, and finally achievi...

The invention belongs to the technical field of power systems, and particularly relates to a new energy comprehensive consumption scheduling method based on source network load storage collaboration, which comprises the following steps: acquiring power grid operation data at the current moment; predicting the load power of the power grid at the next moment based on the acquired operation data; judging the unbalance of the power grid power of the obtained load power of the power grid; when the power of the power grid is unbalanced, on the premise of ensuring that wind power and photovoltaic power are in the maximum output state, judging whether the energy storage system meets the power difference of the power grid or not, and if so, adjusting the charging and discharging power of the energy storage system; otherwise, calculating the secondary difference of the power grid power on the basis of adjusting the charging and discharging power of the energy storage system, and adjusting the load of the power controllable user to meet the secondary difference of the power grid power, thereby achieving the comprehensive consumption scheduling of the new energy.
Description
technical field [0001] The present disclosure belongs to the technical field of electric power systems, and in particular relates to a new energy comprehensive consumption and scheduling method based on source-network load-storage coordination. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The power system is gradually developing in the direction of a new power system with new energy as the main body, and it is necessary to actively promote the integration of power source, network, load and storage and multi-energy complementarity. In order to realize the absorbing capacity of renewable energy, the integrated project of source-grid-load-storage should give full play to the load-side adjustment response ability, carry out the effect analysis of the adjustment and support demand of the large power grid, coordinate and balance the developm...
