TLDR
In this article, the authors considered the dynamic economic dispatch problem with energy storage in a smart grid scenario, which aims at minimising the aggregate generation costs over multiple periods on condition that the time-varying demand is met, while physical constraints on generation and storage as well as system spinning reserve requirement are satisfied.Abstract:
The dynamic economic dispatch problem with energy storage in a smart grid scenario is studied, which aims at minimising the aggregate generation costs over multiple periods on condition that the time-varying demand is met, while physical constraints on generation and storage as well as system spinning reserve requirement are satisfied. In our model, energy storage devices are incorporated for not only inter-temporal energy arbitrage to reduce total generation cost, but also providing spinning reserve to share generators' burden. To solve this problem, we assume that the communication networks are strongly connected directed graphs and propose a fully distributed algorithm based on the `consensus-like' iterative algorithm and the alternating direction method of multipliers. Our algorithm is distributed in the sense that no leader or master nodes are needed, while all the nodes conduct local computation and communicate merely with their neighbours. Numerical simulation is included to show the effectiveness of the proposed algorithm.read more

Consensus-Based Distributed Coordination Between Economic Dispatch and Demand Response
TL;DR: A novel dynamic coordination problem between economic dispatch and demand response is formulated by taking the battery energy storage systems into consideration, which aims at making effective use of the power energy and mitigating the impact of the intermittency of the renewable energy resources.

TL;DR: A two-layer model is proposed for economic dispatch in islanded MGs, in which an MG is considered as the lower layer, while a communication network is consideredas the upper layer, and a systematic method is presented to derive fully distributed control laws from any given communication network.

Power System Dispatch With Marginal Degradation Cost of Battery Storage
TL;DR: This paper rigorously derives the marginal degradation cost of battery for power system dispatch, which takes the form of a constant value divided by a discount factor plus a term related to battery state of health and shows that the optimal marginal costs of degradation depends on the marginal cost of generation in the grid.

TL;DR: This paper critically reviews the reliability impacts of major smart grid resources such as renewables, demand response, and storage and observes that an ideal mix of these resources leads to a flatter net demand that eventually accentuates reliability challenges further.
