Concepts for design of an energy management system incorporating dispersed storage and generation

New forms of generation based on renewable resources must be managed as part of existing power systems in order to be utilized with maximum effectiveness. Many of these generators are by their very nature dispersed or small, so that they will be connected to the distribution part of the power system. This situation poses new questions of control and protection, and the intermittent nature of some of the energy sources poses problems of scheduling and dispatch. Under the assumption that the general objectives of energy management will remain unchanged, the impact of dispersed storage and generation on some of the specific functions of power system control and its hardware are discussed

Performance and Economic Evaluation of Storage Technologies

In the last decade there has been a drastic increase in the penetration of variable generation (VG) such as wind and solar. VG increases the MW variability that must be met in the regulation and reserve markets. If VG penetration levels are allowed to increase without providing additional flexibility in the form of fast response regulation, reserves, and capacity, then the required capabilities will be provided by the existing conventional generation fleet. This do-nothing approach will lead to increased cycling of the existing plants and thus weaken the health of the current grid. The increase VG capacity penetration will also necessitate increased transmission capability in the grid in order to facilitate increased VG energy penetration. All these boils down to endowing the grid with the capability to be flexible by investigating the various options such as transmission expansion, demand control, fast responding generation, VG MW output control, expanding the balancing areas and/or investing in storage technology. In this dissertation, the primary focus is on storage technologies, which is one of the attractive means to meet VG variability due to their fast response. With sufficient energy storage capability, they also promise many other valuable grid services such as peak shaving, load leveling, relieving congestion, increasing VG energy penetration, and deferring generation and transmission expansion plans. The objective and contribution of the dissertation is hinged on developing tools and assessment methodologies to perform economic assessment of storage. The work develops a high-fidelity technology adaptive storage dispatch model for production costing study within a co-optimized energy and ancillary market. This tool is used to investigate the grid benefits and economic viability of different class of storage under various wind penetration scenarios, compare them with other competing solutions, and devise appropriate monetizing schemes for their services. This work also proposes an integrated approach involving production costing and automatic generation control simulation tools to assess short-term storages. Based on the application in IEEE 24 bus system, many conclusions and indicators on storage venture\u27s profitability and risks are drawn

Aerosol measurement and mitigation in CO₂ capture by amine scrubbing

Amine solvent losses are a significant issue for CO₂ capture by amine scrubbing. Solvent lost through aerosol emission represents an environmental hazard with adverse economic implications. This research focuses on developing analytical systems to quantify amine aerosol emissions. Fourier Transform Infrared Spectrometry quantified amine emissions and Phase Doppler Interferometry determined aerosol size and concentration. Baghouse pretreatment of the flue gas significantly reduced amine emissions through collection of aerosol nuclei. A baghouse at the National Carbon Capture Center (NCCC) reduced monoethanolamine (MEA) emission by over a factor of 10. An SO₃ generator was built to facilitate bench and pilot scale aerosol experiments by reacting SO₂ in air over vanadium pentoxide catalyst at 520 °C. Aerosol generation at UT-SRP produced up to 1.7 grams per minute of SO₃, with conversion exceeding 81 %. Bench scale experiments achieved conversion greater than 97 % and aerosol concentration up to 7E4 cm⁻³. SO₃ increased piperazine (PZ) emission by up to 7.6 mol PZ/ mol SO₃. SO₂ increased PZ emission by 1 mol/ mol SO₂, and increased MEA emissions by 3.9 mol/ mol SO₂. H₂SO₄ increased PZ emission by 3 mol/ mol H₂SO₄. PZ resisted aerosol emissions with lower SO₃ content; this is because a low inlet aerosol nuclei concentration results in rapid aerosol growth and subsequent collection by impaction. Higher process temperatures correlated with decreasing PZ emission, supporting the growth and capture theory. Increasing the solvent PZ content was shown to strongly correlate with increasing PZ emission. In bench scale experiments, PZ emission and aerosol size both increased as the PZ content in the solvent increased. Lowering the temperature bulge stage reduced PZ emission and the aerosol size. Increasing the inlet CO₂ correlated with larger aerosol. Increasing the solvent CO₂ loading and the inlet SO₃ resulted in greater aerosol concentration. Operations with a blower upstream of the absorber increased MEA aerosol emission. The upstream blower resulted in larger aerosol in greater quantities, containing a greater quantity of MEA Reduced MEA emission with an intermediate blower are probably due to collection of aerosol through impaction within the blower.Chemical Engineerin
