TLDR
In this article, a review of demand response in renewable energy resources (RERs) is presented, along with a complete benefit and cost assessment of DR and the effects of DR in electricity prices.Abstract:
Dealing with Renewable Energy Resources (RERs) requires sophisticated planning and operation scheduling along with state of art technologies. Among many possible ways for handling RERs, Demand Response (DR) is investigated in the current review. Because of every other year modifications in DR definition and classification announced by Federal Energy Regulatory Commission (FERC), the latest DR definition and classification are scrutinized in the present work. Moreover, a complete benefit and cost assessment of DR is added in the paper. Measurement and evolution methods along with the effects of DR in electricity prices are discussed. Next comes DR literature review of the recent papers majorly published after 2008. Eventually, successful DR implementations, around the world, are analyzed.read more

A Two-Stage Planning Model to Optimize Flexible Resources from Demand Side
TL;DR: In this paper , a two-stage generation expansion planning model considering the impacts of demand response is established to study how resources from the demand side optimize the planning scheme, and three cases are set to compare optimal results which show that with the implementation of demand-response, the expansion capacity of conventional power sources can be reduced to some degree and the load curve can be modified.
Determination of the optimal power generation and co-generation of power and energy in solar and wind units
TL;DR: In this article, the authors investigated the optimal size of a grid independent hybrid system consisting of wind turbines, solar arrays, fuel cells with hydrogen storage and diesel generators, and the objective of this paper is to minimize the system cost and reduce environmental pollutions in the study period.

Balancing Wind and Batteries: Towards Predictive Verification of Smart Grids
TL;DR: In this article, the authors study a smart grid with wind power and battery storage, and cast the problem as a continuous-space Markov decision process with discretized control, for which an optimal deployment strategy minimizes the expected grid frequency deviation.

Grid-side Flexibility of Power Systems in Integrating Large-scale Renewable Generations: A Critical Review on Concepts, Formulations and Solution Approaches
TL;DR: In this paper, the authors define grid-side flexibility as the ability of a power network to deploy its flexibility resources to cope with the changes of power system state, particularly due to variation of renewable generation.

Job Scheduling Under Differential Pricing: Hardness and Approximation Algorithms
TL;DR: This work proves that the job scheduling problems are either APX-hard or NP-hard under two combined price models of DAP and IBR, and presents efficient methods with bounded approximation ratio and shows that the scheduling achieves comparable electricity cost saving.

Robust discrete optimization and network flows
Dimitris Bertsimas,Melvyn Sim +1 more
TL;DR: This work proposes a robust integer programming problem of moderately larger size that allows controlling the degree of conservatism of the solution in terms of probabilistic bounds on constraint violation, and proposes an algorithm for robust network flows that solves the robust counterpart by solving a polynomial number of nominal minimum cost flow problems in a modified network.

Grid of the future
Ali Ipakchi,Farrokh Albuyeh +1 more
TL;DR: In this article, the authors argue that the transition to a smart grid has to be evolutionary to keep the lights on; on the other hand, the issues surrounding the smart grid are signifi cant enough to demand major changes in power systems operating philosophy.
