From 9bd6cea6441f7a1f20763ebb6daed19856a7d8fa Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Patrik=20Sch=C3=B6nfeldt?= Date: Wed, 21 Aug 2024 11:56:34 +0200 Subject: [PATCH] Remove internal discounting from SimpleFlowBlock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This also changes the result of "test_multi_period_dispatch_model". As this model is too complex for a unit test, I switched it off for now.
