摘要：
With the large-scale development of distributed energy resources (DERs) and microgrids (MGs), the output power range of MGs and the permeability of DERs are mutually restricted under the static security constraints of distribution network. However, since the existing DER planning model does not take the original output power range of MGs into account, the operation space of MGs may be limited under the obtained planning scheme, which increases the control difficulty of MGs and operation risk of distribution network. To solve this proplem, the site selection and capacity determination of DERs in the distribution network containing MGs are studied, considering the effect of dispatchable region of MGs, demand response (DR) and operation strategy of energy storage system (ESS). In order to reduce the impact of DER access to grid on MG operation, the dispatchable region of MG is introduced to quantitatively depict the output power boundary of MG, and the interval arithmetic is used to transform it into the constraints of planning model. The users' interruptible load probability matrix is proposed to characterize the uncertainty of DR. Furthermore, a DER planning model for the distribution network containing MG is established considering the interests of distribution network operator and DER investor, and an improved particle swarm algorithm is used to solve the planning model. Case results show that the obtained DER planning scheme can achieve optimal economic in ensuring that the dispatchable region of MG is not affected, proving the rationality and effectiveness of the proposed model. © 2019 Automation of Electric Power Systems Press.
