2016年，中国的太阳能和风能产量大幅减少，特别是在西北地区。本文认为，行政因素和市场壁垒是导致可再生能源弃电的主要原因。2017年，西北电网（NWPG）成功实施了多种方法来减少风能和太阳能弃电。在本文中，我们分析了2017年各省发电量的变化、可再生能源供应的扩大和电力替代项目。在承认NWPG努力取得实际成果的同时，我们也认识到西北地区在整合可再生能源方面仍然面临的挑战。我们认为，跨区域的行政壁垒阻碍了全国范围内可再生能源的有效利用。为解决这些障碍，我们探索促进大规模可再生能源并网的市场化机制。除了各省之间的可再生能源长期合同外，现货市场和辅助服务市场都将促进可再生能源的利用。此外，应该利用价格信号来引导调峰。市场机制将有助于消除障碍，提高可再生能源在全国的利用。
In 2016, solar and wind energy production were greatly curtailed in China, especially in its northwestern region. This paper identifies administrative factors and market barriers as the main causes of renewable curtailment. In 2017, the Northwest Power Grid (NWPG) successfully implemented a variety of approaches to reduce wind and solar curtailment. In this paper, we analyze the change in power generation, expansion of renewable energy delivery, and electricity-replacement projects across provinces that occurred in 2017. While acknowledging the practical results of the NWPG's efforts, we identify challenges that the northwest still faces in integrating renewable energy. We argue that trans-regional administrative barriers are preventing the effective utilization of renewable energy nationwide. To address those barriers, we explore market-based mechanisms for promoting the integration of large-scale renewable energy. In addition to long-term contracts for renewable energy across provinces, both spot-market and the ancillary service market would facilitate the uptake of renewable energy. In addition, price signals should be used to guide peak shaving. Market mechanisms will be insightful to dissolve barriers and enhance utilization of renewable energy throughout the country.
