Endogenous Assessment of the Capacity Value of Solar PV in Generation Investment Planning Studies

PROJECT TITLE :

Endogenous Assessment of the Capacity Value of Solar PV in Generation Investment Planning Studies

ABSTRACT:

There exist many completely different reliability- and approximation-based mostly methods to determine the contribution of solar resources toward resource adequacy. But, most of these approaches require knowing in advance the installed capacities of each typical and solar generators. This is a complication since generator capacities are actually call variables in capacity coming up with studies. During this paper, we have a tendency to study the impact of your time resolution and solar PV penetration using a designing model that accounts for the total distribution of generator outages and solar resource variability. We also describe a modification of a standard deterministic coming up with model that enforces a resource adequacy target through a reserve margin constraint. Our numerical experiments show that at least 50 days value of information are necessary to approximate the results of the complete-resolution model with a most error of 2.5p.c on costs and capability. We tend to also show that the number of displaced capacity of typical generation decreases rapidly because the penetration of solar PV will increase. We notice that using an exogenously outlined and constant capability value based on time-series knowledge can yield relatively accurate results for small penetration levels. For higher penetration levels, the modified deterministic coming up with model better captures avoided prices and therefore the decreasing value of solar PV.
