In the literature , the source-network-load-storage coordinated control research is carried out on the AC/DC hybrid microgrid in three modes that can be flexibly switched from the perspective of second-level control, thereby achieving accurate control of AC and DC power and meeting differentiated power quality requirements in different regions.
Therefore, this paper proposes a source–storage–load coordination and optimization strategy based on edge computation, which deploys “edge nodes” at the points close to the data, and coordinates and optimizes the source–storage–load based on edge computing.
Besides, flexible loads represented by electric vehicles, demand-response loads (interruptible loads and translatable loads) and the rapid development of energy storage systems, on the one hand, have greatly improved the system's regulation ability. On the other hand, it has also brought a huge test to operation and management level of the system.
In order to control the fluctuation of the grid load and reduce the peak-to-valley difference of the load, the distributed PV and energy storage plants are considered as "negative load" to define the equivalent load .
The energy storage cost factor is set as the time of us, as shown in Table 1; the system network wastage cost factor is set as 0.25; The interruptible load compensation coefficient is 0.1. Solve the model.
A short- and long-duration cooperative energy storage method is proposed for the systems of photovoltaics and wind farms combined with energy storage components, such as batteries, thermal energy storage, and hydrogen energy storage, to balance economy and reliability .
