Stochastic coordination of joint wind and photovoltaic
This paper presents an optimal bid submission in a day-ahead electricity market for the problem of joint operation of wind with photovoltaic power systems having an energy
Solar and wind plants will be major contributors to low-carbon power grids, but there's a key obstacle to their profitability, the authors write. Without changes, it may be more difficult for future renewables projects to make a profit.
Few studies have optimized global deployment of photovoltaic and wind power. Here we present a strategy involving construction of 22,821 photovoltaic, onshore-wind, and offshore-wind plants in 192 countries worldwide to minimize the levelized cost of electricity.
But there's an important obstacle to their profitability: revenue decline. Adding wind and solar to the grid tends to reduce electricity prices during the times that they generate. On a sunny afternoon in California, solar generation can reach such high levels that it brings the price of electricity down to zero.
In our optimal case, the projected cost reduction by technological improvements 20 and the low-cost energy sources identification at sub-national scales 23 together lead to a faster growth of PV and wind-power generation than the prediction based on the historical trends.
Without changes, it may be more difficult for future renewables projects to make a profit. Dramatic reductions in the cost of wind and solar have led to optimism that they can be primary contributors to low-carbon electricity grids. But there's an important obstacle to their profitability: revenue decline.
Interconnection enables movement of renewables over larger spatial scales, allowing renewable energy to find its way to distant markets where prices are higher. In the end, though, the net profitability of wind and solar farms is the outcome of two opposing forces: technological progress reducing cost and revenue decline reducing income.
