Scenario-Based Multiobjective Decision-Making of Optimal Access Point for Wind Power Transmission Corridor in the Load Centers

Abstract: Because of uneven geographical distribution characteristics of wind power and load centers in China, large-scale wind power should be delivered to central or southeast load centers through a transmission corridor over great distances. However, it is found that the load demand, vulnerability, safety, stability, and economy of power systems would be the criteria for the selection of the access point for the wind power transmission corridor. The decision-making result also varies with wind power penetration and load level. Hence, this paper presents a scenario-based methodology for selecting the proper access point. The scenario generation and reduction approach are used to generate several representative wind power penetration and load levels. The multiobjective decision-making problem is suggested to be solved based on theory of information entropy and the analytic hierarchy process (AHP) method. The established index system takes into account the active power demand, vulnerability of power system transmission networks, power system safety and stability, and operational economy. This method was used to select an access point for Hubei Province in central China that receives large-scale wind power from northern China. The results demonstrate the effectiveness of the proposed methodology for selecting the access point of a wind power transmission corridor.

Analysis of Wind Power Ancillary Services Characteristics with German 250-MW Wind Data

Abstract: With the increasing availability of wind power worldwide, power fluctuations have become a concern for some utilities. Under electric industry restructuring in the US, the impact of these fluctuations will be evaluated by examining provisions and costs of ancillary services for wind power. This paper analyzes wind power in the context of ancillary services, using data from a German 250 Megawatt Wind project.

Setting with the Sun: The Impacts of Renewable Energy on Wholesale Power Markets

Abstract: Policies supporting investment in renewable electricity have been a cornerstone of climate policy in many parts of the world. While previous empirical work explores the economic and environmental impacts of renewable production, the focus has exclusively been on the short-run impacts of expanding renewable supply. In this paper, we shed light on the longer run impacts of renewable expansions. Focusing on the California electricity market, we estimate how wholesale electricity prices have responded to a dramatic increase in utility-scale solar capacity. While a substantial decline in daily average prices can be attributed to the solar capacity expansion, this average price impact masks a substantial decrease in mid-day prices combined with an increase in shoulder hour prices. These results imply that short-term power markets are responding to the renewable expansion in a fashion that could sustain more flexible conventional generation, while seriously undermining the economic viability of traditional baseload generation technologies.
