Distributed generation (DG) can provide significant value to power systems by reducing the energy and emission costs of centralized generation, but its value can be impacted by transmission line capacity. Revenue losses for DG projects may occur due to this, but considering the environmental value of DG, this loss could pose a problem.
Distributed generation (DG) can offer significant value to power systems by reducing some of the energy and emission marginal costs of centralized generation. These costs can change significantly with the expansion of power systems, especially when renewable energy integration is supported on large new transmission capacity. Accordingly, these cost and price changes could have a potentially large impact on the system value of DG. In this paper, we assess the impact of increasing transmission capacity, for a massive integration of renewable energy, on the energy and environmental system value of solar PV, wind, and energy storage DG. To illustrate this, a case study is presented based on the main Chilean electric power system. We found significant variations in the DG value with different transmission line capacity levels. For instance, just the energy value of PV and storage DG changed up to 43% and 100%, respectively, for line capacity levels growing from 0% (no line) to 200%, in one key transmission line analyzed. This can also represent a strong impact on the revenue of DG projects, generally paid based on this energy value. Furthermore, DG revenue losses can be problematic considering that DG still offers a significant environmental value. (c) 2021 Elsevier Ltd. All rights reserved.
