Why Wind is Not Coal: On the Economics of Electricity

-The economics of electricity is shaped by its physics. A well know example is the non-storability of electricity that cause its price to fluctuate widely. More generally, physical constraints cause electricity to be a heterogeneous good along three dimensions -time, space, and lead-time. Consequently, different generation technologies, such as coal and wind power, produce different economic goods that have a different marginal economic value. Welfare maximization or competitiveness analyses that ignore heterogeneity deliver biased estimates. This paper provides an analytical welfare-economic framework that accounts for heterogeneity for unbiased assessments of power generators. The framework offers a rigorous interpretation of commonly used cost indicators such as 'levelized electricity costs' and 'grid parity'. Heterogeneity is relevant for all generators, but especially for variable renewables such as wind and solar power. We propose a definition of 'variability', derive the opportunity costs of variability, and link that concept to the 'integration cost' literature. A literature review shows that variability can reduce the value of wind power by 20-50%. Thus it is crucial that economic analysis accounts for the physics of electricity.

“…As increasing penetration of wind power, wind power brought great threaten to the system stability because of fluctuation and uncertainty of the wind. Especially, the great change of wind power in short time which is called as a ramp is very harmful to the power grid [2][3][4][5][6][7]. In order to get a reasonable and efficient prediction model to forecast ramp events, each country has done a lot of research.…”

Abstract. Description of probability distribution characteristics of wind power ramp events is always a challenge in grid-connected wind power operation analysis. In this paper, a moving ratio based approach of wind power ramp events is introduced and an probability model is described for the wind ramp events. The proposed model is useful to estimate the relationship between power ramp events and the variability of the wind power. The proposed model is able to satisfactorily approximate the actual distribution of wind power ramp events . It is shown that the linear difference based ramp distribution can be calculated using the proposed moving ratio based approach. The proposed model can be an effective tool in planning for wind power ramp control.

“…The output of RESs is stochastic and intermittent. [4] In an autonomous grid, which lacks of spinning reserve capacity, the energy storage unit (ESU) is needed to stabilize the output of RESs and secures the reliability of power supply. [6,8] Whereas for small islands (less than 1 MW), Battery energy storage systems (BESS) seem to be the viable choice [5], pumped storage plants, as the most technically mature solution, are suitable for large and medium islands with appropriate geographical conditions.…”

Abstract. The rapid development of wind power provides a new solution for power supply of isolated island. However, due to the intermittent and stochastic nature of renewable energy resources (RES), the energy storage unit (ESU) is required for power grid reliability. This paper proposed an automatic programming method for autonomous grid in isolated islands. The sea water pumped storage plant serves as ESU to counter-balance the fluctuations of RESs. The penetration level of RES and the profit of the Island system operator (ISO) increase significantly. With the geographical and historical data of an island in China, the effectiveness of the proposed method is testified.
