Simultaneous charge and discharge of Hot TES

[zolanaj]

When there is excess heat from the CHP system the model doesn't distinguish between incurring round-trip efficiency losses and sending heat to waste, leading to cases in which TES simultaneously charges and discharges heat.

Here’s an example, where you can see it on June 1-2 from the initial view of the heating thermal dispatch:

When waste heat is permissible, this reporting can likely be avoided in postprocessing. Ordering the dispatch, whether by an epsilon-level incentive for waste heat or forcing it via binaries, is likely a secondary option to avoid having to tune a new parameter or add computational complexity, respectively.
