Abstract

Abstract Renewable energy sources (RES) are the key element of sustainable energy systems. To accommodate the intermittency of wind (and solar) electricity generation, energy storage is critical. The aim of the study was to evaluate the potential of wind energy storage in the existing hydropower plant reservoirs in Latvia with the pumped hydroelectric energy storage (PHES) technology, considering the current and projected future wind energy capacities. An algorithm was developed and used for data aggregation and analysis, calculations, and forecasting. The three River Daugava hydroelectric power plants are the largest electricity producers in Latvia, and their generation capacity depends on seasonal variations. Currently, Latvia's electricity generation from RES is the highest during the spring season when maximum hydropower potential is utilized. However, wind energy has a potential to grow and could supplement hydropower throughout the year. Decreasing the existing administrative procedure heaviness to faster achieve the climate neutrality targets and energy autonomy by increasing RES development in Latvia is a way to create sustainable energy production. A rational future scenario in Latvia is to expand wind parks and integrate pumped hydroelectric energy storage systems in the existing cascade hydropower plants.

双重可再生能源积累:以风能和水能为例

摘要可再生能源(RES)是可持续能源系统的关键要素。为了适应风能(和太阳能)发电的间歇性，能源储存至关重要。该研究的目的是考虑到当前和预计的未来风能容量，评估拉脱维亚现有水电站水库利用抽水蓄能技术储存风能的潜力。开发了一种算法，用于数据汇总和分析、计算和预测。三个道加瓦河水电站是拉脱维亚最大的电力生产商，它们的发电能力取决于季节变化。目前，拉脱维亚的可再生能源发电量在春季是最高的，此时水电潜力得到了最大的利用。然而，风能有增长的潜力，可以全年补充水力发电。通过增加可再生能源的发展，减少现有的行政程序，以更快地实现气候中和目标和能源自主，是创造可持续能源生产的一种方式。在拉脱维亚，合理的未来方案是扩大风电场，并将抽水蓄能系统整合到现有的梯级水电站中。
