A functional grid corresponds to a stable steady state, such that any bifurcation can have catastrophic consequences up to a blackout. But also the existence of multiple steady states is undesirable, as it can lead to transitions or circulatory flows. Despite the high practical importance there is still no general theory of the existence and uniqueness of steady states in such systems. Analytic results are mostly limited to grids without Ohmic losses. In this article, we introduce a method to systematically construct the solutions of the real power load-flow equations in the presence of Ohmic losses and explicitly compute them for tree and ring networks. We investigate different mechanisms leading to multistability and discuss the impact of Ohmic losses on the existence of solutions.}, cin = {IEK-STE}, ddc = {530}, cid = {I:(DE-Juel1)IEK-STE-20101013}, pnm = {153 - Assessment of Energy Systems – Addressing Issues of Energy Efficiency and Energy Security (POF3-153) / CoNDyNet 2 - Kollektive Nichtlineare Dynamik Komplexer Stromnetze (BMBF-03EK3055B) / ES2050 - Energie Sytem 2050 (ES2050) / VH-NG-1025 - Helmholtz Young Investigators Group "Efficiency, Emergence and Economics of future supply networks" $(VH-NG-1025_20112014)$}, pid = {G:(DE-HGF)POF3-153 / G:(DE-JUEL1)BMBF-03EK3055B / G:(DE-HGF)ES2050 / $G:(HGF)VH-NG-1025_20112014$}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:31893663}, UT = {WOS:000505563100008}, doi = {10.1063/1.5122739}, url = {https://juser.fz-juelich.de/record/872568}, }
