“…In addition, electric vehicles [2] and multiple energy storage devices [3] also have huge dispatching potential, which can effectively smooth the power fluctuations brought by new energy sources. Distributed energy storage system (DESS) is composed of battery energy storage system (BESS), flywheel energy storage system (FESS) and other small, distributed energy storage systems connected to the customer-side or LVN (low-voltage network) [4] . It can effectively stabilize the fluctuation of new energy.…”

Distributing energy has facilitated the interaction between electricity, heating, and gas systems. Aggregating flexible resources in the optimal scheduling process of multi-energy microgrids can promote the complementary coordination of multi-energy systems and reduce useless energy waste. In this paper, flexible resource aggregation analysis is added to the optimal scheduling problem of multi-energy microgrids. Firstly, a resource aggregation model based on Mincowski addition is proposed to fully characterize the schedulable potential of flexible resources. Then, a multi-energy microgrid collaborative optimal scheduling model is established to fully exploit the operational potential of flexible resources. Finally, a numerical example is simulated to verify the validity of the aggregation model and control algorithm above-mentioned, which improves the efficiency and accuracy of optimal control of multi-energy microgrids.

With the growth of distributed energy storage system (DESS) connected to the distribution network, reasonable siting and sizing of the DESS have become real issues affecting its further development. This paper proposes a new sequential optimal placement method based on node comprehensive sensitivity coefficient (NCSC) and battery life cycle cost (BLCC), which considers siting and sizing of DESSs from aspects of rationality and economy. Firstly, considering the charge-discharge characteristic of energy storage, the sensitivity on system node voltages and active power loss, a new indicator called NCSC is proposed to measure the optimality of the installation location of DESS. Secondly, a cost-benefit model based on BLCC is established for optimizing the capacity of DESS. On the basis of above research, specific steps of the novel sequential placement strategy are presented. The simulation on IEEE33 bus system verified the validity of the proposed optimization method; the analysis shows it can effectively improve rationality and economy of DESSs.
