<h1>Motivation<a class="headerlink" href="#motivation" title="Permalink to this headline">¶</a></h1>
<p>This is part of an independent study to apply statistical approaches to describing renewable curtailment events.
Primarily, we are motivated by the following questions:</p>
<ul class="simple">
<li><p>What are explanatory or predictive variables that can predict economic solar curtailment in the California grid?</p></li>
<li><p>What are the policies and mechanisms that are used to deploy economic curtailment?</p></li>
<li><p>Given a day ahead weather forecast, can we predict the net load (total load - renewable intermittent generation)?
- With a week ahead forecast?</p></li>
<li><p>Can we calculate or measure the economic value from existing curtailment practices?</p></li>
</ul>
<div class="section" id="background">
<h2>Background<a class="headerlink" href="#background" title="Permalink to this headline">¶</a></h2>
<p>As intermittent sources of generation continue to grow, overcapacity may result in events where generation may exceed available demand.  Balancing authorities must decide how to ramp down total generation to keep the grid in balance.  Currently the CAISO approaches oversupply primarly through economic curtailment <a class="bibtex reference internal" href="zreferences.html#californiaiso2017" id="id1">[CAI17b]</a>.  Other approaches to managing supply include expanded energy storage, demand response programs, <a class="reference internal" href="glossary.html#term-tou"><span class="xref std std-term">TOU</span></a> rates, reductions in minimum generation, expanding the western <a class="reference internal" href="glossary.html#term-eim"><span class="xref std std-term">EIM</span></a>, increasing flexible capacity, integrating more EVs and improving regional coordination <a class="bibtex reference internal" href="zreferences.html#californiaiso2017a" id="id2">[CAI17a]</a>.  The goal of this study is to better inform and understand exogenous variables that contribute to oversupply.</p>

<h2>Problem Statement<a class="headerlink" href="#problem-statement" title="Permalink to this headline">¶</a></h2>
<p>This project attempts to produce a statistical model trained on publicly available historic forecasts, and past curtailment events in California to predict whether the state of the California grid would end up producing a significant curtailment event.</p>
