Integrated Optimal Dispatch, Restoration and Control for Microgrids
… by proposing an approach which integrates optimal dispatch, sequential microgrid restoration and control algorithms. Potential cyberattack paths are identified by creating a detailed cyber-physical system model for microgrids. A two-tiered intrusion detection system is developed to detect …

INCREASING ENDURANCE IN TACTICAL DC MICROGRIDS WITH VARIABLE GAIN DROOP CONTROL
… an optimized droop control scheme to achieve an optimal power dispatch with respect to efficiency. Optimal dispatch was determined using the combined generator fuel consumption as a function of the output power. The optimal dispatch was achieved by deriving the corresponding droop gains.

Unit commitment : tight formulation and pricing
… to generators' incentive 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 …

Fast optimal power flow analysis for large-scale smart grid
Optimal power flow OPF plays an important role in power system operation. The emerging smart grid aims to create an automated energy delivery system that enables two-way flows of electricity and information. As a result, it will be desirable if OPF can be solved in real time in order to allow the …

Optimal Volt/VAR Control and Power Dispatch in Active Distribution Systems
… work. These problem statements include economic dispatch, multi-objective economic-emission dispatch, economic-reliability security-constrained optimal dispatch, and multi-objective Volt/VAR control in modern distribution systems. In addition, we propose various methods of solving the …

Mathematical framework for designing energy matching and trading within green building neighbourhood system
… systems (GBNS). To do so, the need to obtain the optimal and economical dispatch of energy matching and trading should be expressed at the same time. Although, there are some solutions in literature but there is still a lack of mathematical framework for energy matching and trading in GBNS. In …

Architectures and Algorithms for Distributed Generation Control of Microgrids
… architecture for frequency regulation and optimal dispatch designed to take advantage of microgrid-specific properties. For microgrids with no inertia, we propose a control architecture that is designed to drive the average frequency error to zero while ensuring that the frequency at every …

Coupled Natural Gas and Electric Power Systems
… plants for the electric power system. The optimal dispatch of coupled natural gas and electric power systems is posed as a relaxed convex minimization problem, which is solved using the feasible point pursuit (FPP) algorithm. For a decentralized solution, the alternating direction method of …

Solving dynamic economic dispatch problems using pattern search based methods with particular focus on the West Doha Power Station in Kuwait
This thesis is concerned with Dynamic Economic Dispatch (DED) problems, in particular in the context of the current and future needs of the electrical power system in the State of Kuwait. General Economic Dispatch (ED) issues are addressed, under both static and dynamic conditions, with valve-point …
