Convex relaxation based locational marginal prices for electricity markets
… and analyze semidefinite relaxation-based locational marginal prices (RLMPs) for real and reactive power in electricity markets. Our analysis reveals that when the nonconvex economic dispatch problem has zero duality gap, the RLMPs exhibit properties similar to locational marginal prices …

Impact of distributed energy resources on locational marginal prices and electricity networks
… models, and quantifies the influence of DERs on prices of electricity, networks and environmental effects. There is an evolving role between distribution and transmission system operations. Quantitative modeling and a qualitative literature, industry and regulatory review were utilized to …

Unit commitment : tight formulation and pricing
… to deviate from the optimal dispatch under locational marginal prices. In this dissertation, we first propose a convex relaxation of UC based on a primal formulation of the Lagrangian dual problem. This convex relaxation is used (i) to solve the convex hull pricing problem in polynomial …

Operation under Uncertainty in Electric Grid: A Multiparametric Programming Approach
… forecasting of real-time operations and locational marginal prices. Conditioning on the current system state, we provide a full distribution of future operations and prices. For operational decision making, we propose an optimal stochastic approach to interchange scheduling in multi-area …

Statistical Analysis of Electric Energy Markets with Large-Scale Renewable Generation Using Point Estimate Methods
… introduced to the system variables (electricity prices, congestion levels etc.). In order to economically operate the system and efficiently run the energy market, a statistical analysis of the system variables under uncertainty is needed. Such statistical analysis can be performed through an …

A Unified Adaptive Robust Optimization Approach to Electricity Markets Under Uncertainty
… operator hedges, while it is priced through new marginal pricing mechanisms. In Chapter 2, we provide marginal pricing for uncertainty in ARO as a technical enabler of the proposed market. We derive locational marginal prices for unit commitment problems with ARO under load and capacity …

Active power ancillary service provision of commercial building energy storage resources
… deployment of VSHPs and PEVs in response to locational marginal prices (LMPs), while satisfying distribution network (DN) operational constraints. DA market clearing and price-based demand response (DR) are modeled with stochastic optimization problems. Simulated case studies are then …

The comparative economic assessment of the impacts of energy storage and demand response resource participation in the day-ahead electricity markets
… supply-demand balance results, at times, in high prices, marked price volatility, and even price spikes. These price issues, along with advances in storage and communication technology, have reinvigorated the drive of policymakers, system planners and operators, private investors and other …

Distribution Network Operation with High Penetration of Renewable Energy Sources
… on the active and reactive distribution locational prices (D-LMPs) within the distribution market environment is explored in terms of the maximization of SW considering the uncertainty related to solar irradiance, wind speed and load demands. Finally, a realistic case study (16-bus UK …
