Title: Analyzing storage for wind integration in a transmission-constrained power system

Abstract

High levels of energy from variable generation sources such as wind and solar photovoltaics (PV) can result in significant curtailment, in which the wind and PV energy cannot be used to serve demand. Adding transmission and energy storage can assist in reducing renewable curtailment, but the relative merits of each enabling technology individually or combined is not well understood. Thus, we compare the role of transmission and storage in reducing curtailment, as well as reducing generation costs from conventional sources. Using a high-fidelity model of the electric power grid, we examine a scenario in which the western portion of the U.S. and Canada reaches 37% energy from wind and 12% energy from solar PV. In the case studied, we find that transmission is generally more effective than energy storage in reducing curtailment, due to the curtailment patterns of wind. However, the interaction between transmission and energy storage shows that the two technologies act symbiotically, meaning that their combined energy value is greater than that of each individually. This analysis demonstrates that fully realizing the benefits of wind resources located far from demand centers will require an effective method to deliver wind power at the right times to the right locations.

Modeling the Impact of Flexible CHP on the Future Electric Grid In California

Technical Report Desai, Jal ; Ruth, Mark ; Lemar, Paul ; ...

The US electric grid is changing fundamentally: not only are the generation sources that supply the grid changing, but so too are the profiles of the loads that use the electricity. Traditionally, generation followed a fairly predictable demand pattern, which allowed a baseload fossil fuel generation infrastructure to run constantly at a high capacity factor to meet the minimum load, with less capital-intensive, flexible generation used to meet the additional varying load. However, recently, the country began shifting fossil generation moved from coal-based to natural gas–powered electricity generation, and renewable generation has increased steadily. In California, utility-scale renewable energy generationmore »« less

The Potential Role of Concentrating Solar Power within the Context of DOE's 2030 Solar Cost Targets

Conference Murphy, Caitlin ; Sun, Yinong ; Cole, Wesley J ; ...

For solar electricity generating technologies to be cost competitive at a large scale with conventionally generated electricity, cost reductions are needed for both concentrating solar power (CSP) and solar photovoltaic (PV) systems. In 2011, the U.S. Department of Energy (DOE) established solar cost targets that corresponded to reducing CSP and PV prices by approximately 75% in order to achieve a levelized cost of electricity (LCOE) of $0.06 per kilowatt-hour (kWh) for both utility-scale PV and high-capacity factor CSP-TES systems in 2020. Utility-scale PV achieved its 2020 cost target in 2017, and recent estimates for the LCOE of CSP-TES with amore »« less

On the Path to SunShot - Emerging Issues and Challenges in Integrating High Levels of Solar into the Electrical Generation and Transmission System

Technical Report Denholm, Paul ; Clark, Kara ; O'Connell, Matt

Increasing the use of grid-flexibility options (improved grid management, demand response, and energy storage) could enable 25% or higher penetration of PV at low costs (see Denholm et al. 2016). Considering the large-scale integration of solar into electric-power systems complicates the calculation of the value of solar. In fact a comprehensive examination reveals that the value of solar technologies—or any other power-system technology or operating strategy—can only be understood in the context of the generation system as a whole. This is well illustrated by analysis of curtailment at high PV penetrations within the bulk power and transmission systems. As themore »« less

Solar Building Energy Storage Management - MicrogridXpert

Technical Report Barrows, Tyler ; Belz, Andrew ; Moussa, N. Albert ; ...

Throughout the world and the U.S., increases in solar PV adoption have occurred due to lower prices, government incentives and concern for the environment. Due to their variable intermittent power output, solar PV is being paired with batteries to smooth their output. This presents many challenges in terms of cost optimization, stability, and control of power flow. Microgrids are being introduced as a solution to maximize the effectiveness of such systems. As the grid becomes more decentralized and distributed generation reaches about 20% of the grid (which can occur in some local areas), grid stability becomes more susceptible to themore »« less
Enabling Technologies for High Penetration of Wind and Solar Energy

Conference Denholm, P

High penetration of variable wind and solar electricity generation will require modifications to the electric power system. This work examines the impacts of variable generation, including uncertainty, ramp rate, ramp range, and potentially excess generation. Time-series simulations were performed in the Texas (ERCOT) grid where different mixes of wind, solar photovoltaic and concentrating solar power provide up to 80% of the electric demand. Different enabling technologies were examined, including conventional generator flexibility, demand response, load shifting, and energy storage. A variety of combinations of these technologies enabled low levels of surplus or curtailed wind and solar generation depending on themore »« less
