Optimal Planning of Distributed Photovoltaic in Integrated Electricity and Heat Systems

In order to tackle the energy crisis, plenty of researches have focused on the integration of renewable energy, such as the wind power and the distributed photovoltaic (DPV). However, the penetration of DPVs in the individual power system is restricted due to the operational limits. Hence, the integrated electricity and heat system (IEHS) has been developed to improve the system flexibility and enlarge the penetration of DPV. This paper presents an optimal planning method of DPV in IEHS, which formulates the optimization model of DPV planning according to the modeling of the multi-energy networks. In order to reduce the curtailment of DPVs, the penalty cost of DPVs is integrated to the objective of the proposed planning model. Numerical simulation results demonstrate the effectiveness of the proposed planning method.
