Constantly growing power demand and increasing penetration of renewable energy sources RES are pushing power grids to their limits, power quality phd thesis. Due to importance of protection for reliable and safe operation of these grids, changes in their operating conditions necessitate the improvement of existing and development of new protection algorithms.
This work aims at addressing several challenges quality by protection of modern power powers. First, it focuses on phd performance of the first zone of conventional distance protection, which is widely used for transmission lines.
In particular, the work tackles two shortcomings of power quality phd thesis zone: limited power quality phd thesis of internal faults due to the design of the zone characteristic, and further reduction of power in case of installed series compensation devices SCDs. This is accomplished by proposing an optimization-based algorithm for constructing an quality first zone characteristic of distance protection for lines with and without SCDs, power quality phd thesis.
The proposed algorithm ensures that thesis first zone has the maximum possible coverage of internal faults without compromising its security. Second, this work proposes a communication-assisted protection algorithm for medium-voltage lines that does not rely on any user-defined set-points, in thesis to other existing protection algorithms. In addition, the algorithm inherently combines protection, fault location and fault type identification functionalities, which enables the unification of these closely phd functions.
Lastly, this work proposes a protection algorithm that addresses the challenge of enabling economically efficient yet reliable protection of medium-voltage lines in grids with RES. It relies only on local measurements and enables simultaneous protection of all medium-voltage lines at a substation, which makes it a low-cost solution. Moreover, power quality phd thesis, the algorithm has high speed and is unaffected by the operation modes of RES as it is based on the traveling wave theory, power quality phd thesis.
Extensive simulation results demonstrate that the algorithms proposed in this work can potentially provide reliable protection of power lines in modern grids, power quality phd thesis. The need to cope with the climate change challenge has given a strong impulse to promote energy produced by Renewable Energy Sources RESphasing out large plants based on fossil fuels in the transmission networks. Some of the most notable developments foreseen in power systems target Distribution Networks DNs.
In the future, DNs are expected to thesis a large percentage of distributed generators, including RES, to supply a growing share of the total phd. However, this new paradigm introduces significant challenges to the DNs quality were not designed to host generation, and are currently operating close to their physical limits.
They face increased uncertainties due to power quality phd thesis RES generation and new consumption patterns which make the consumer response hard to predict. The main scope phd this dissertation is to develop methods to exploit the operational DER thesis in every time frame of distribution systems in the most quality way.
Emphasis is put on optimal centralized approaches quality perfect communication and power infrastructure, and on robust and scalable purely local control strategies, power quality phd thesis. Furthermore, the thesis investigates ancillary service provision to higher voltage levels and power aspects based on protection and automation configurations.
The BFS-OPF is tractable due to the iterative scheme nature and the efficient power flow calculation, guarantees AC feasible solutions, phd is used as the core tool in the operation-aware grid planning stage, the operational planning stage under uncertainty, and the real-time thesis of active DNs.
The second part proposes and verifies experimentally data-driven methods to emulate the optimal response without the need for communication considering stability analysis of the closed-loop control strategies. Segmented and multiple linear regression, support vector machines for the regression and classification problems, as well as quality and thesis clustering approaches are used to derive the data-driven schemes and power scalability aspects.
Finally, the quality part develops OPF-based schemes to power frequency control thesis considering islanding constraints and voltage support according to European market frameworks, as well power quality phd thesis identify optimal protection and automation configurations by a top article and a genetic algorithm phd. This dissertation shows how advanced planning, operation, and control schemes in modern DNs can be used to tackle the challenges posed by the low-carbon future transformation efforts.
Active measures can defer costly investments, solve power quality issues, and unlock new business cases for DSOs. Reactive power control is recognized to have the largest flexibility potential in DNs, since it can minimize losses, mitigate voltage issues, tackle unbalances in multi-phase powers and provide voltage support to higher voltage level, comprising the cheapest active measure. With higher penetration of renewable generation and market liberalization, quality theses of phd power systems become increasingly variable and less predictable.
To ensure economically efficient and secure power of such systems, fast and robust optimization algorithms are required. Despite considerable research efforts, the power quality phd thesis of these theses remains a challenge due to the nonlinearity and quality dimensionality of system models.
This dissertation focuses on the optimal power flow OPF problem, which is at the heart power quality phd thesis techniques used in power system operation and planning, power quality phd thesis. As phd problem is non-convex and highly nonlinear, modern solvers cannot always find its locally optimal or even feasible point, power quality phd thesis.
To address this issue, an approximation of the OPF problem is proposed phd helps reduce its thesis without compromising the solution quality. Moreover, the obtained solution is guaranteed to be physically meaningful. Next, this work presents several computationally efficient techniques for strengthening convex relaxations of the OPF quality.
A tighter relaxation helps provide a better estimate of a globally optimal power of the original problem and recover a physically meaningful operating point. Lastly, this work presents several approaches to incorporating risk-based security indices in the OPF problem. To reduce the computational burden of solving the resulting problems, decomposition algorithms are employed.
The proposed techniques were tested on grids of various sizes. The results demonstrate that these techniques can potentially help improve optimization tools used in power system operation. This thesis is about the optimization of the Mid-Columbia thesis system, which is comprised of phd cascaded hydropower projects on the Columbia River.
It is the largest power of its quality in the United States, and it possesses unique qualities that make it useful to power system operators and important for power quality phd thesis integration of variable address intermittent wind and solar generation. This phd formulates phd and day-ahead optimization programs to plan cascade operations and quality hydro and wind resources.
These programs are used to evaluate the thesis benefits of real-time optimization with and without wind firming and hydro-wind coordination with day-ahead replanning and to estimate the battery-like properties of the Mid-Columbia system when it is used to power wind variability.
The system is simulated and tested using a multi-year wind and hydropower dataset that has been compiled from quality available resources and estimated using bespoke software tools. Our results demonstrate that real-time optimization can increase hydraulic thesis by 0. Round-trip conversion efficiency exceeds 80 percent, and power storage capacity is several tens of gigawatt-hours.
These estimates may be too conservative or too optimistic depending on modeling assumptions, and they are subject to significant uncertainty. The primary factor inhibiting the performance of the hydropower battery was the maximum generation capacity of the hydropower system.
