Book Description
In order to address air quality and greenhouse gas impacts of power generation, the state of California has implemented a renewable portfolio standard (RPS) goal of integrating 33% renewable energy into the grid by 2020. This research considers several renewable energy integration scenarios for the state of California including various mixtures of geothermal, biogas, wind, solar thermal, and photovoltaic energy. Criteria pollutant emissions are spatially and temporally resolved in order to study the impacts of meeting the California's Renewable Electricity Standard. One of the main challenges of increasing renewable penetration is the unpredictable and variable generation profile. Production can be highly dependent on weather, as in the case of wind and solar generation. Sudden changes in weather can cause spikes and dips in power production. These intermittencies in renewable generation must be balanced in order to maintain grid reliability. The renewable energy implementation scenarios address grid reliability by considering various strategies including energy storage, distributed generation, plug-in electric vehicles (PEV), and dispatchable peaking and/or load following gas power plants to complement the intermittent renewable energy. Six 33% scenarios (CAISO/CPUC LTPP Trajectory Mix 1, Trajectory Mix 2, Trajectory Mix 3, Environmentally Constrained, Cost Constrained, Time Constrained) are evaluated. Additionally, baseline scenarios are compared to the renewable scenarios.

Book Description
Drastic changes need to occur in the electricity generation and transportation sectors in order to address environmental concerns that have attracted attention in recent years. These concerns, combined with increasing energy prices, have led to elevated interest in alternative, and low to non-carbon technologies in both sectors from both researchers and policymakers. In the state of California, integration of renewable resources, and switching to more environmental-friendly transportation options, have been mandated by stringent environmental regulations such as AB 32, AB 118, and RPS goals. A spatially and temporally resolved resource dispatch model is developed that simulates the operations of an electricity market while taking into account all the physical constraints associated with various components of an electricity grid such as transmission system constraints. Multiple modules are also developed to provide inputs to the model and also determine the interaction between electricity generation and transportation sectors. This dispatch model and its modules are used to assess a selected set of future transportation and electricity generation scenarios. These scenarios include various dispatch strategies, integration of renewables, and deploying plug-in electric vehicles. The results show that with appropriate planning, the generation, transmission, and distribution sectors will be able to accommodate a high penetration of plug-in vehicles, and they will result in an overall reduction in criteria pollutant and greenhouse gas emissions. With vehicle smart charging, the need for planning in the generation sector is minimized and the installed generators will be able to handle the extra load caused by the vehicles. Different dispatch strategies are developed and results indicate that the best approach to reduce emissions while keeping the system's costs at acceptable levels is a combination of economic and environmental dispatch strategies. This strategy can also be used to dispatch renewable resources as a part of the market instead of using the current must-take strategy. The methodology and the tools developed provide a means to examine various aspects of future scenarios and their impacts on different sectors, and can be used for decision making and planning purposes.

Book Description
The global wind and solar PV industry has transitioned from a subsidy-dependent niche market to a commercially viable sector that is dominating global capacity expansions. However, integrating these renewable energy resources, with their variable nature, onto the electricity grid poses new challenges for system operations. This thesis explores variable renewable energy (VRE) integration, through multiple scales of energy modelling and analysis from the integrated assessment model MESSAGE, to the country-scale electricity system model LEAP, and the production cost model introduced in this work entitled SILVER. The MESSAGE and LEAP models have large-scale, long-term representations of the energy system that enable analysis of alternative energy policies, cross-sector environmental impacts, and overarching cost trends, but do not have the spatial-temporal resolution to represent site-specific, variable VRE generation profiles. Thus, SILVER, for the Strategic Integration of Large-capacity Variable Energy Resources, is designed as a highly flexible production cost dispatch tool. Technologically, SILVER represents the full gamut of grid balancing strategies: building flexible and dispatchable generation assets, interconnecting geographically dispersed resources and VRE types, shifting flexible loads through demand response, shifting generation profiles through storage technologies, curtailing excess generation, interconnecting the electricity sector with the transport sector, and improving VRE forecasting methodologies. SILVER relies on hourly wind and solar generation time-series data, produced by the newly developed GRETA (Global Renewable Energy Atlas Time) tool, which has been launched as an open access web-portal. SILVER is applied to three VRE integration applications: moving towards a fully-renewable Ontario electricity system including 87% VRE penetration, demand response, electric vehicles, storage assets, and an expanded transmission network; quantifying storage asset commercial viability in electricity systems with different flexibility factors, VRE penetrations, and financial remuneration mechanisms; and exploring the role of decentralized generation and electric vehicles at a city-scale in a developing country context. The results demonstrate the highly system-specific nature of VRE integration, with the VRE resource typology, the non-VRE system flexibly, VRE penetration, and degree of VRE centralization having significant impacts. The interdependence between these electricity system factors in terms of curtailment rates, GHG emissions, electricity system costs, and flexibility requirements recommends an integrated planning approach.

Book Description
This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.

Book Description
Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.
